Mutum 3 & Amrul Asraf Mohd-Any 1 Received: 15 June 2015 / Accepted: 26 February 2016 / Published online: 11 March 2016 # Institute of Applied Informatics at University of Leipzig 2016 Abstract Developing switching barriers to retain customers has become a critical marketing strategy for online retailers. However, research on the role of switching barriers in eretailing is still limited. Recent trends show that when competitors are just one click away, it is questionable if customer loyalty can be achieved at all in online environments. This leads to the research question on whether switching barriers have any impact on e-loyalty in pure-play retailers. The paper examines the influence of switching barriers on customer retention (i.e., estore loyalty) and further investigates the moderating effects of switching costs and alternative attractiveness. Data were gathered via a survey of 590 shoppers of online pure-play retailers in the UK. Findings show that customer satisfaction and the two dimensions of switching barriers (perceived switching costs and perceived attractiveness of alternatives) significantly influence customer loyalty. Contrary to findings in earlier studies, it was found that switching costs did not moderate the relationships between satisfaction and loyalty nor between perceived attractiveness of alternatives and loyalty. The paper makes imperative recommendations to develop switching barriers and to foster loyalty along with suggestions for future research. Responsible Editor: Christopher P.

Advertising Introduction The increased competition in the online marketplace and high costs for getting access to new customers have required eretailers to continually emphasize on customer retention and loyalty strategies (Otim and Grover 2010; Polo et al. 2011). Customer retention and loyalty is especially acute in the online environment since the “competing offer is just a few clicks away” (Shankar et al. 2003, p. 154). For example, Harris and Goode (2004, p. 139) note that “generating loyal customers online is both more difficult and important than in offline retailing.” Balabanis et al. (2006) show that some satisfied customers might not consider themselves loyal to the estores, indicating that acquiring and retaining customers online is not particularly straightforward. However, customer retention has become “an economic necessity” (Balabanis et al. 2006, p. 214), as the cost of acquiring new customers can be up to five times as costly as maintaining existing ones (Bauer et al. 2002). Consequently, for retailers operating in the online environment, developing switching barriers to induce loyalty has become a critical marketing strategy (Alt and Österle 2013). Despite the critical role of switching barriers in marketing, research in this area have focused predominantly on the offline context (e.g., Jones et al. 2002; Burnham et al. 2003). More research is needed to understand the effectiveness of switching barriers in online retailing (e.g. Goode and Harris 2007; Mutum et al. 2014), 158 especially as the competition intensifies and consumers have numerous alternatives to which they can switch very easily (e.g., Bakos 1997; Friedman 1999; Holloway 2003). Hence, it is particularly important to understand the role of attractiveness of alternatives in developing switching barriers. In addition, while some studies have employed switching costs as their main construct, there has been very little effort to develop robust measures of online switching costs. The multifaceted typologies and dimensions of switching costs denote the complex nature of the construct. Yet, empirical research in this area has treated switching costs as unidimensional (e.g. Fuentes-Blasco et al. 2010; Goode and Harris 2007; Kim and Son 2009), measuring such costs as a global construct. This approach ignores the conceptual richness of the switching costs construct, which is too complex to be operationalized as unidimensional (Burnham et al. 2003). Aydin et al. (2005) specifically highlight the need for further research to investigate the sub-dimensions of switching costs. In addition, Carlson and O’Cass (2011) highlight the importance of distinguishing between online pure-play retailers (online retailers with no physical retail presence) and bricksand-clicks companies (retailers with both online and offline presence). Holloway (2003) showed that with bricks-andclicks retailers, stronger consumer relationships can be developed compared to online only retailers. Thus, failure to differentiate between the two types of online retailers (pure-play vs. bricks-and-clicks) may further distort the results or lead to over-estimation of relationships. A review of extant research in switching behavior reveals that no studies have looked at customer retention of online pure-play retailers. To fill the above gaps, this research represents the first attempt at studying switching barriers explicitly with respect to online pure-play retailers. The aims of this study are threefold. (1) First, the study develops an online customer loyalty framework of customer retention/switching by explicating switching barriers. By capturing the key factors likely to trigger e-loyalty, the study is unique in studying the role of alternative attractiveness and switching costs conjointly in the context of loyalty and satisfaction towards an online retailer (Chen and Hitt 2002). (2) Second, the study incorporates and evaluates the moderating effects of switching costs in order to provide further insights into the nature of e-loyalty, previously suggested as an area for future research (Mutum et al. 2014). (3) Finally, the study advances the literature on online marketing with the validation of a multi-dimensional measurement scale of switching barriers (Pappas et al. 2014). Thus, the study fills important gaps in the online marketing knowledge that links switching costs, alternative attractiveness, and e-store loyalty. With an increase in popularity of online pure-play retailers, this study is also important from a managerial perspective. A recent report (Retailpro 2015) revealed that 44 % of British shoppers do more than half of their online shopping on pureplay retailers. Thus, for online retailers, implications exist in E. Ghazali et al. constructing switching barriers that increase customer satisfaction and loyalty. By articulating customer-focused strategies that foster loyalty, the study is expected to help managers with the validation of a multi-dimensional measurement scale of switching barriers, providing a useful tool to operationalize switching barriers. The rest of the paper is organized as follows: first, the study reviews the literature on online switching costs, identifying the existing gaps and developing the hypotheses. Subsequently, it discusses in detail the research methodology employed in this study. This is followed by the results of the analysis. Finally, the study findings are presented, discussed, and concluded. Literature review In the section that follows, the paper presents the key literature pertaining to online switching barriers and customer loyalty. This provides an overview of extant literature and reveals the gaps which the study aims to fill. Building customer retention and loyalty Ranaweera and Prabhu (2003) noted two principal strategies to building customer retention. The first is to improve customer satisfaction, so that the customer ‘wants’ to stay with the firm. The second is to increase the perception of ‘switching barriers’, which impede customer switching. These strategies could also be applied to the online retail setting to induce customer loyalty. Oliver (1999) describes loyalty as the overall attachment and deep commitment to product, brand, organization, or retailer. Customer loyalty is crucial for a firm’s success because loyal customers enhance its profitability (Reichheld 1996), market share (Chaudhuri and Holbrook 2001), and shareholder value (Sindell 2000). The importance of customer loyalty cannot be emphasized enough in the context of online marketplaces, especially for pure-players, where it is generally held that customers are able to terminate a relationship with a mere ‘click of the mouse’ (Anderson and Srinivasan 2003; Reichheld and Schefter 2000). Therefore, without core loyal customers, pure-players may find it difficult to remain afloat because developing loyalty is not as clear cut as some studies have suggested (e.g., Coelho and Henseler 2012; Emanuelsson and Uhlén 2007). For example, despite being assumed as a prerequisite to customer loyalty, customer satisfaction does not automatically predict loyalty. Previous studies have established imperfect correlations between the two constructs, and the strengths of their relationships remain highly questionable (e.g., Balabanis et al. 2006; Dagger and David 2012; Emanuelsson and Uhlén 2007). Hence, when investigating the loyalty inducing influences (Coelho and Henseler 2012), satisfaction along with other factors that drive customer retention should be considered, including switching Constructing online switching barriers costs, competitors’ offerings (Burnham et al. 2003; Jones et al. 2002), and alternative firms (Roberts 1989). Understanding switching barriers When the perception of switching barriers is high and the options to exit a relationship are limited, the tendency for loyalty increases (Hirschman 1970). A useful definition of switching barriers is provided by Jones et al. (2000, p. 261), who conceptualized it as “…any factor, which makes it more difficult or costly for consumers to change providers.” However, there is some confusion between the terms ‘switching barriers and ‘switching costs’ (Balabanis et al. 2006; Colgate et al. 2007), with many authors using them interchangeably (e.g. Bansal and Taylor 1999; Mathwick 2002). Although Goode and Harris (2007) noted “subtle differences between switching barriers and costs” (p. 517), they fail to describe any clear differences. Ranaweera and Prabhu (2003) assert that the switching barriers construct encompasses ‘self-efficacy’ as well as ‘facilitating condition’ issues. Other authors, namely Burnham et al. (2003) and Jones et al. (2000, 2002), have conceptualized switching barriers (offline service context) as a multidimensional construct encompassing several categories and dimensions. According to Jones et al. (2000, 2002), switching barriers is made up of three main dimensions, namely, perceived switching cost, attractiveness of available alternatives, and interpersonal relationships, while switching barriers as conceptualized by Burnham et al. (2003) does not include attractiveness of alternatives. In this research, we adapt and extend the framework conceptualized by Jones et al. (2000), considering switching barriers as a multidimensional construct. However, since the focus of this research is on the customers of pure play online retailers, the interpersonal relationship construct does not apply because compared to a physical market environment, there is a considerable lack of face-to-face interaction (Szymanski and Henard 2001) between customers and retailer employees in the online market, which precipitates the importance of the interpersonal relationship component. As such only perceived switching costs and attractiveness of alternatives are examined in this research. These key concepts and their antecedents are explained in the subsequent sections. Barrier 1: Perceived switching costs In the B2C context, Patterson and Smith (2003) define switching costs as “the perception of the magnitude of the additional costs required to terminate a relationship and secure an alternative one” (p. 108). Some researchers have questioned the credibility of a single global measure to represent perceived switching costs, although most studies have 159 conceptualized it as unidimensional. According to Fornell (1992), perceived switching costs are complex and as such require a higher level of abstraction. Fornell also suggests that due to its complex nature, perceived switching costs are difficult to measure. Although researchers have questioned the credibility of its single global measure, there have been only few attempts to empirically measure it as a multifaceted construct (e.g. Burnham et al. 2003; Jones et al. 2002). Most of these studies are done in the offline context. Due to these inconsistencies, there is a need to unify the current theoretical discussion and to develop a set of switching costs pertinent to other contexts, such as an online retail setting. Based on a comprehensive literature review (Balabanis et al. 2006; Burnham et al. 2003; Colgate et al. 2007; Fornell 1992; Jones et al. 2002; Thatcher and George 2004; Mutum et al. 2014), we identified five dimensions of perceived switching costs (see Table 1). As perceived switching costs are highly salient in the online environment where customers are often co-producers of the services they receive, three categories of online switching costs are identified. They are: the procedural costs components (learning costs, search and evaluation costs, and uncertainty costs), the economic or monetary costs component (artificial costs), and the relationship-based or psychological costs component (brand relationship loss costs). Barrier 2: Attractiveness of alternatives Another construct underlying customer online switching barriers is that of perceived alternative attractiveness. This refers to customers’ perceptions of the extent to which viable competing alternatives are available in the marketplace (Jones et al. 2000). Individuals’ commitment to a relationship should increase when they are satisfied with the relationship and/or when there are no good alternatives available. Further, not only does a large perceived difference among alternatives lead to customer retention, but the lack of perceived differences also influences customers to stay in existing relationships. According to Patterson and Smith (2003), when a customer perceives that alternatives are no different from their existing provider or does not perceive them as ‘any more attractive’ than their existing relationship, they tend to remain loyal to their current provider. In this situation, the customer’s perception is that switching is not worthwhile (Colgate and Lang 2001) because the net benefit from alternative relationships is not superior to the current relationship (Hennig-Thurau et al. 2000). Overall, the offline marketing literature suggests the presence of at least three factors affecting customers’ perceptions of the attractiveness of alternatives: existence of alternatives, heterogeneity (severity of difference) among alternatives, and high switching costs between alternatives. Based on these 160 factors, we label the three dimensions of alternative attractiveness (Table 2) for the online pure-play market as retailer indifference, alternative awareness, and alternative preference. On the whole, our review of the literature, looking into factors influencing customer retention in the online environment, revealed that research into switching barriers is, unquestionably, lacking (Mutum et al. 2014). Therefore, extant theories and normative insights vis-àvis customer retention/customer switching in the context of the online milieu need to be re-examined. In addition, previous research on switching behaviors of customers, have predominantly focused on the offline purchasing contexts. The limited number of online studies on switching behaviors of customers has used hybrid samples, that is, they have not differentiated between customers of brick-and-click and pure-player online retailers. This study addresses these above gaps by scrutinizing online customer loyalty/switching behaviors only in the context of pure-player entities. Hypothesis development Building on the literature review, this section develops the study’s framework and corresponding hypotheses. Relationships between the key constructs are theorized and hypotheses are put forward for subsequent testing, here in the context of online pure-play retailers. Customer satisfaction and loyalty Customer satisfaction is one of the most critical constructs and a core concept in marketing (Garbarino and Johnson 1999; Holloway 2003; Mittal and Kamakura 2001). This study focuses on the overall satisfaction, that is, the cumulative judgment overtime of customers with regards to a retailer’s performance (Anderson et al. 1994; Burnham 1998). A few authors have argued that satisfaction is not a prerequisite to loyalty and/or customer retention. In other words, increased satisfaction may not necessarily lead to an increase in loyalty to firms, and evidence shows that dissatisfied customers often remain with a retailer (Bolton and Drew 1991; Burnham et al. 2003) and that satisfied customers still buy elsewhere (Keaveney 1995) or do not necessarily buy more (Seiders et al. 2005). Thus, the role of satisfaction in influencing loyalty is more complicated than initially thought (Dagger and David 2012; Mittal and Kamakura 2001; Oliver 1999). However, there is substantial empirical evidence in the literature linking global cumulative satisfaction to loyalty (Oliver 1997; Szymanski and Henard 2001). In essence, consumers are E. Ghazali et al. likely to develop positive intention towards behavior (i.e., repeat purchase or online transaction) (Albert et al. 2014), if they have a positive attitude (i.e., feeling of satisfaction based on past performance) towards the behavior. Thus, in this paper, customer satisfaction is hypothesized to be associated with loyalty, which is conceptualized as the ‘mindful’ mode of customer repeat purchase. Hence, we postulate that: H1: Satisfaction positively affects loyalty, in online pureplay retailers. Attractiveness of alternatives and loyalty Customer consideration of alternatives is a key element in making choices about whether to stay or defect (Patterson and Smith 2003; Rust and Kannan 2003). Past studies have found that when switching costs are perceived as high, as experienced by customers, such high switching cost perceptions will have a negative influence on the attractiveness of alternatives. In other words, customers consider that switching to other companies is less desirable due to higher switching costs and consequently, the customer eventually loses interest in the company’s competitors (Kim and Son 2009). On the whole, there is a tendency for switching cost perceptions to reduce (a) the level of customer consideration of other alternatives (Heide and Weiss 1995), (b) the customer’s effort in searching for alternatives (Weiss and Heide 1993) as well as (c) their propensity to search for alternatives (Zauberman 2003). As the perceived attractiveness of alternatives increases, customers are more likely to be involved in solving problems and less likely to remain loyal (Hirschman 1970; Ping 1993; Rusbult et al. 1982) and the probability of switching increases (Bendapudi and Berry 1997; Jones et al. 2000; Sharma and Patterson 2000). Rusbult et al. (1982) observed that the perception of high quality alternatives positively influences exit and negatively influences loyalty. Similarly, Jones et al. (2002) and Yim et al. (2007) showed that attractiveness of alternatives had negative effects on commitment and repurchase intention. Thus, we hypothesize that: H2: Attractiveness of alternatives inversely affects loyalty, in online pure-play retailers. Switching costs and loyalty According to Jones et al. (2002, p. 441), switching costs are barriers that “hold customers in service relationships.” Switching costs in this study refers to ‘perceived’ switching costs (Morgan and Hunt 1994) as it is not any objective cost Constructing online switching barriers Table 1 161 Components of perceived switching costs Dimension Description Learning costs Expenditure of time and effort to learn, understand or use the new service effectively. This includes familiarizing with conducting transactions on an unfamiliar website. Actions initiated by a firm to retain customers and to make it more expensive for them to switch suppliers. For example, frequent flyer program. Customer’s perception of future costs or losses associated with possible negative consequences incurred by switching to an unfamiliar or untested retailer. This is closely linked to the perception of risk such as performance risk, financial risk, convenience risk and privacy and security risks. It incurs when searching for a suitable alternative retailer to switch to. Two types of search costs as potential reasons for customers remaining with a retailer (lock-in); ‘physical search cost’ and ‘cognitive search cost’. The feeling of loss in leaving a brand. Strong brand image and positive brand attitude reinforce the relationship between customers and retailers, making the switching process more costly. Artificial costs Uncertainty costs Search and evaluation costs Brand relationship loss costs that will be measured, but rather the switching costs as perceived by customers (Burnham et al. 2003). Fornell (1992) suggests that while satisfaction makes it harder for competitors to take away a firm’s customers, switching costs make it costly for customers to defect to competitors. Indeed, switching costs can be more critical an antecedent to customer retention than satisfaction because customers tend to attribute greater weight to them when making decisions (Dick and Basu 1994). Many scholars agree that one potential but crucial antecedent to loyalty is switching cost (e.g., de Ruyter et al. 1998; Rust and Kannan 2003). It has also been argued that switching costs positively influence loyalty and retention (Fornell 1992). For example, Patterson and Smith (2003) and Bell et al. (2005) found significant direct effects of switching costs on customers’ propensity to remain with a firm. This is also evident in the online B2C relationships (e.g., Anderson and Srinivasan 2003; Chen and Hitt 2002). The process of changing to alternatives will involve Table 2 Source Burnham (1998, p. 107) Jones et al. (2002) Klemperer (1987) To (1996, p. 31) Colgate and Lang (2001) Mitchell (1999) Burnham et al. (2003) Forsythe and Shi (2003) Chen and Hitt (2002) Bakos (1997) Johnson et al. (2003) Burnham et al. (2003) Polo and Sesé (2009) extra investment in searching, evaluating, and filtering information. Therefore, we postulate that: H3: Perceived switching costs positively affects loyalty, in online pure-play retailers. Moderating effects of switching costs The above discussion sets the foundation for the study’s final hypotheses, which posit that the effects of switching costs are not only evident in its direct effect on e-loyalty, but is also shown indirectly, as a moderation variable, through its more complex influence on satisfaction and alternative attraction, in the online pure-play market. Most offline retailing studies have regarded switching costs as a moderator in satisfaction and loyalty relationships (Yang and Peterson 2004). For instance, Burnham et al. (2003) found that switching costs impose a moderating effect on repurchase intention through Dimensions of alternative attractiveness Dimension Description Source Retailer Indifference The overall perception that because most other retailers are similar (i.e., retailer indifference), it may not be worthwhile to search for alternatives. The customers’ high awareness of alternatives (i.e., competitors) in the market, possibly due to the customers’ experience in online shopping. The customers’ preference for alternatives’ (competitors’) service and offerings to their current retailer’s. Similar to Balabanis et al.’s (2006) ‘parity barriers’ Alternative Awareness Alternative Preference Comparable to Balabanis et al.’s (2006) ‘unawareness barriers’ Concurs with Li et al. (2006) and Rusbult et al.’s (1998) ‘quality of alternative’ dimension 162 E. Ghazali et al. satisfaction in two service industries (viz., credit card and phone call service). Similar results were observed in mobile phone service (Lee et al. 2001). Hauser et al. (1994) reported that a strong level of perceived switching costs reduces the sensitivity of a customer to perceived satisfaction. Likewise, Anderson and Sullivan (1993) discovered a negative relationship between switching costs and customer satisfaction sensitivity in the banking industry. However, opinion with regards to the moderating role of switching costs in the e-retailing environment is quite mixed. Some scholars argue that this role may not always be significant and will depend on other variables such as the types of business, customers or products (Nielson 1996). For example, Balabanis et al. (2006) found that switching costs will only moderate the e-satisfaction and loyalty links, when esatisfaction is higher than average. However, Holloway (2003) while looking at online service failure recovery, found no moderating effect of switching costs on the relationship between satisfaction and repurchase intention. Similarly, Chen and Hitt (2002) did not find any moderation as well. Due to the mixed findings in prior research, the moderating role of switching costs warrants further investigation. Therefore: H4: Perceived switching costs will moderate the relationship between satisfaction and loyalty. Attraction towards alternatives in the market will strongly and negatively influence the development of loyal customers. However, the prevalence of switching costs can serve as Fig. 1 Conceptual framework of switching barriers. RI: Retailer Indifference; AP: Alternative Preference; AA Alternative Awareness are derived and labelled after running CFA. LC Learning Costs, AC Artificial Costs, UC Uncertainty Costs, SE Search and Evaluation Costs, BR Brand Relationship a buffer against the negative impact of high attractiveness of alternatives on loyalty. For example, a customer may feel that there is price unfairness if a competitor offers a lower price compared to their current e-retailer. The logical action of the customer is to end the current relationship and establish a new one with the competitor. This action, however, is not without any cost (Xia et al. 2004). If the customer decides to leave the relationship, they may incur switching costs that include time, effort, and money. Thus, the costs of action will most likely moderate the relationship between attractiveness of alternatives and loyalty. The empirical evidence with regards to this effect has been negligible (Holloway 2003) in the literature. Hence, we postulate that: H5: Perceived switching costs will moderate the relationship between attractiveness of alternatives and loyalty. Figure 1 shows our conceptual framework. Research method To achieve the aims of the research, a quantitative research methodology was conducted. This section presents the research that was implemented to test the framework, including the data collection and succeeding rigorous process of data analysis.

The respondents were required to evaluate one e-retailer from which they most frequently purchased. This method of soliciting respondents to report their experience with providers has been widely accepted in prior research (e.g. Balabanis et al. 2006; Li et al. 2006). As a guideline, the sample must be composed of individuals in the UK who are Internet shoppers of pure online retailers. According to the ONS (2014), two in every five adults (40 %) aged 65 and over bought goods or services online in 2014. This is more than double the 2008 estimate (16 %). A mailing list comprising a random sample of 4000 consumers was purchased for single use from Experian UK’s pre-existing database of online shoppers. The sample was restricted to online shoppers over the age of 16, who are categorized as adults by the Office for National Statistics UK, and who had transacted at least once in the last 6 months. Data collection Data were collected via a self-administered questionnaire using a hybrid survey approach (i.e., web with mail design) (Dillman et al. 2009) in order to reduce non-response error (de Leeuw et al. 2008). A packet containing a paper questionnaire, a personalized cover letter, and postage paid returned envelope were sent out to all the potential respondents. They were given the choice to complete via either paper or online questionnaire hosted on Surveymonkey.com. Out of the 4000 questionnaire packets mailed, 163 were returned as ‘undelivered’, leaving 3837 potential respondents. After a month, a total of 799 responses were received of which 578 came through the post, while the rest (221) were collected online. Since our study focuses on pure-play firms, 209 responses were removed - either because they were unusable or because they chose websites of companies with strong offline presence as well. A total of 590 responses were used for the final analysis, which corresponds to approximately 15.4 % response rate. Table 3 presents the profiles of the respondents. We compared estimates of demographic characteristics to the general population1 to assess the quality of the sample in terms of both non-coverage and non-response and can conclude that our sample is representative of adult Internet shoppers in the UK. Table 4 presents the online retailers selected by the respondents in descending order of frequency. The findings show that the three most dominant pure-players for consumers in 1 Population reports were derived from Nielson-Online (2009), MintelOxygen (2007) and British Population Survey (January 2008). 163 the UK are Amazon UK, Play.com, and Amazon.com (US). Amazon UK is quite distinct from the US site with respect to several features and some products are available exclusively on each of the sites. The respondents are experienced shoppers on their favorite e-retailer in general. More than half of the respondents have been purchasing from the e-retailer for more than 3 years. Most respondents also indicated that they had visited the website at least once every 2 months, with one-third of the respondents doing so at least twice a month. With respect to the frequency of purchase from their retailer’s website, more than half of the respondents purchased at least once every 3 months with a number of purchases being made at least three to five times a year. In terms of money spent on their retailer’s website, 66 % of the respondents spent between £10 and £40 per transaction. The products purchased most frequently were books and CDs/DVDs. Other popular products included clothing, electrical items, and computers. Measures Respondents were asked to indicate their level of agreement on 7-point Likert-type scales derived from previous studies, anchored by 1 = strongly disagree and 7 = strongly agree. To operationalize overall satisfaction, we adapted three modified items from Voss et al. (1998), Seiders et al. (2005), and Bourdeau (2005). We adapted the loyalty scale using five items from Bourdeau (2005). The five second-order dimensions of switching cost were measured as follows: 6-item learning cost, 7-item artificial cost, 6-item uncertainty cost, 5-item search and evaluation cost, and 3-item brand relationship loss (Bourdeau 2005; Burnham et al. 2003; Holloway 2003; Jones et al. 2007; Korgaonkar and Wolin 1999; Mathwick 2002). Attractiveness of alternatives was measured using nine items (Burnham 1998; Holloway 2003; Li et al. 2006; Ping 1993). Table 5 provides a list of the measures and their psychometric properties after purification. Our questionnaire was pre-tested by two academics who are experts in the area of e-service and consumer behavior followed by another 15 individuals who are familiar with online shopping. The hypotheses are tested following the assessment of psychometric properties of the measurement scale. Structural equation modeling is used for this purpose using AMOS 18 software package. Reliability and validity of measures Confirmatory factor analysis was used to assess the validity and reliability of our multi-item scales (Gerbing and Anderson 1988). As shown in Table 5, all the average variance extracted and composite reliabilities exceed the standard thresholds in the literature (Bagozzi and Yi 1988). Though the loadings of UC1 (0.58) and BR2 (0.51) are lower than the recommended 164 Table 3 Comparative demographic profile of respondents (N = 590) E. Ghazali et al.

Consistent with the literature, our analysis confirmed that the construct Alternative Attractiveness must be viewed at a higher level of abstraction with three second-order sub-dimensions. However, from the nine proposed items to measure this construct, three ‘problematic’ items were removed, leaving six items reflecting the sub-dimensions. Similar to Balabanis Table 4 Respondents’ selection of pure-play online retailers et al.’s (2006) ‘parity barriers’ and ‘unawareness barriers’, we named the first two dimensions ‘Retailer Indifference’ and ‘Alternative Awareness’, respectively. Retailer Indifference refers to the overall perception that because most other retailers are similar, it may not be worthwhile searching for alternatives. Alternative Awareness refers to the customers’ high awareness of competitors in the market, possibly due to the customers’ experience in online shopping.

(2006) and Rusbult et al.’s (1998) ‘quality of alternative’ dimension and is labeled Alternative Preference, reflecting the customers’ preference for a competitor’s service and offerings to their current retailer’s. With regard to the two second-order switching barriers constructs (switching costs and alternative attractiveness), we conducted additional tests to assess convergent validity by linking the first-order dimensions to their second-order global construct and the path coefficient estimates must be significant (Benson and Bandalos 1992). As a result, convergent validity was established for switching costs and attractiveness of alternatives. To assess discriminant validity between all constructs, we examined the Chi-square (χ2) difference between the standard model and the ‘non-discriminant’ model at unity (Anderson and Gerbing 1988; Bagozzi et al. 1991) and found that the constructs and sub-constructs in our model are distinct from each other; hence discriminant validity was confirmed as well. Results of the hypotheses tests Results of structural equation modeling (Table 6) show the overall good fit measures are all within the thresholds indicating acceptable fit (re = 1743; (=1df) = 1.972; NNFI = 0.99 > .95 = good fit; CFI = 0.929 > .90; RMSEA = 0.040 < .05 = good fit; SRMR = 0.057 < .08). The NFI, GFI, and AGFI measures are not reported here because they are no longer recommended (Hu and Bentler, 1999; Kenny 2014). H1 is supported (1 = 0.10; p < 0.05), which indicates that overall satisfaction is positively related to loyalty. As reflected by the strong and highly significant negative relationship between alternative attractiveness and loyalty, alternative attractiveness acts as an important driver in reducing loyalty. H2 is therefore supported (β = −0.58; p < 0.01). Similarly, as perceived switching costs is posited to have an effect on loyalty, H3 is also supported (β = 0.18; p < 0.01). H4 and H5 argue that switching costs moderate the relationship between overall satisfaction and loyalty, and alternative attractiveness and loyalty, respectively. To test this, we applied the orthogonalization or residual centering approach (Little et al. 2006), whereby the 4-step approach in creating orthogonalized latent interaction variables was strictly followed. This procedure, to a large extent, eliminates multicollinearity issues that have, in the past, plagued many efforts to model interactions via SEM. Besides, this method also uses all possible information of the manifest variables to test the effect, in contrast to previous methods. Compared to the standard mean-centered approach (e.g., Aiken & West, 1991), this approach ensures complete orthogonality between the independent and the interaction variable and hence, leads to identical inferences and better fitting results (Little et al. 2006; Marsh et al. 2007). However, the latent interactions SAT*PSC and ATA*PSC on loyalty were not significant. Therefore, both H4 and H5 were not supported. Discussion Our results are in line with the findings of some earlier studies, which found a positive relationship between satisfaction and loyalty (e.g., Corstjens and Lal 2000; Evanschitzky and Wunderlich 2006) and in the online context (e.g., Anderson and Srinivasan 2003; Balabanis et al. 2006; Harris and Goode 2004; Methlie and Nysveen 1999).

This raises the question whether customer defection can be controlled successfully by simply managing customer satisfaction. The results of previous studies have also found that satisfaction explains very low variance in repurchasing behavior (Balabanis et al. 2006; Bolton 1998; Mazursky et al. 1987). According to Reichheld (1996), more than 50 % of customers generally defect, despite being happy, or even delighted with a company. Even though we found that satisfaction explains only 10 % of variance in loyalty, dissatisfaction may not necessarily result in defection. Therefore, we can conclude that our findings support Chebat et al. (2010), which found that managing satisfaction and/or service quality are not the only way to foster customer loyalty. However, most companies seem to be bound by this narrow and uncreative belief – the so called ‘satisfaction trap’ (Reichheld and Schefter 2000). Another possible explanation is that the linkage between satisfaction and loyalty is nonlinear. In other words, loyalty increases only after satisfaction passes a certain critical threshold (supporting Chebat et al. 2010; Dick and Basu 1994; Mittal and Kamakura 2001). This implies that online customers must be highly satisfied before loyalty develops. Thus, retaining customers on the basis of satisfaction metrics alone may not be a very sensible strategy. The findings also reveal that between the two components of switching barriers conceptualised in the model, alternative attractiveness plays a greater role as a driver of customer loyalty. This is evidenced by the huge negative impact perception of alternative attractiveness has in influencing loyalty (standardized coefficient = −0.58 of 58 %). In other words, the lower the perception of good alternatives available in the market, the more loyal customers will be. It would appear that an e-retailer is not as well protected by new entrants in the online environment as their offline counterparts, as this result contradicts studies in the offline environment. In the offline environment, switching costs play a greater role in determining loyalty as compared to alternative attractiveness, where competitive insulation appears to be more substantial. This has been found especially among studies on continuous and/or contractual service (e.g., financial, credit card and phone services, etc.). Our results also provide convincing evidence to conclude that online switching costs have positive and direct effects on loyalty. This is in line with a few studies, which looked at retailing in the offline context (Burnham et al. 2003; Tsai and Huang 2007; Tsai et al. 2006). Also, it is worth mentioning here that two previous studies failed to find a significant direct effect of switching costs on loyalty (viz., Jones et al. 2000; Yang and Peterson 2004). Interestingly, our results reveal that switching costs (18 %) explain loyalty more powerfully as compared to satisfaction (10 %). Previously, Burnham et al. (2003) found that the influence of switching costs on customer intention to purchase to be stronger than satisfaction. The findings show that switching costs are, indeed, a very important factor for loyalty and of course customer retention, contrary to past assertions about the negligibility of switching costs in the online context (see for e.g., Holloway 2003; Bakos, 1997). Our hypothesized moderating effects in the satisfactionloyalty and attractiveness-loyalty relationships were not significant. This suggests that switching costs have only direct positive effect on loyalty and not a moderating effect. This contradicts the findings of other past studies in other contexts. For example, Jones et al. (2000), Ranaweera and Prabhu (2003), and Aydin et al. (2005) found negative moderating effects of switching costs on service satisfaction and repurchase intention or loyalty. On the other hand, Lee et al. (2001) found positive moderating effects of switching costs on satisfaction and loyalty. It should be noted that these studies involved either ‘high-touch’ offline services (viz., hair salon: Jones et al. 2000) or contractual services contexts (viz., financial services: Jones et al. 2000; telecommunications services: Aydin et al. 2005; Ranaweera and Prabhu 2003; Lee et al. 2001). The study highlights that customer retention of online pure-play retailers is quite unique and we cannot assume that relationships between satisfaction, switching barriers and loyalty are same as in bricks-and clicks or offline retailers. 168 Conclusion This paper takes a fresh look on the influence of online switching barriers and customer satisfaction on customer retention, and examines the moderating effects of switching costs in the context of online pure-play retailers (online retailers who have no physical retail presence). The study advances current understanding of online customer retention/switching by explicating switching barriers from a more nuanced perspective and linking these to an online customer loyalty framework. Data were gathered via a survey of 590 shoppers of online pure-play retailers in the UK. Findings show that customer satisfaction and the two dimensions of switching barriers (perceived switching costs and perceived attractiveness of alternatives) significantly influence customer loyalty. Contrary to findings in earlier studies, it was found that switching costs did not moderate the relationships between satisfaction and loyalty nor between perceived attractiveness of alternatives and loyalty. As explained next, the paper has imperative managerial implications to foster loyalty online. Managerial implications This study has several significant implications for marketing managers in the online retailing sector. First, managers must manage their switching barriers more systematically. As indicated by the study, switching barriers ensures that customers have more incentives to remain loyal to the firm. However, managers must remember that managing customer satisfaction is simply not enough to secure loyalty from their customers. They need to be cognizant of the importance of perceived switching barriers while preparing marketing plans/initiatives, which seek to maintain customer loyalty (in the online marketplace). In particular, the research findings highlight the strategic importance of perceptions of barriers to switching in a more comprehensive manner. The findings also suggest that there is a need for marketing managers to deliberate on the notion of attractiveness of alternatives, which is closely related to the perception of firm heterogeneity or differentiation in strategy research. Managers need to understand that the perceived lack of good alternatives, forms formidable barriers to exit and hence is a vital factor in customer retention. On the other hand, this is also relevant to new start-ups seeking to challenge the more established retailers. Even though the effect of service differentiation on customer retention was not evaluated in this study, we suggest offering one-stop shopping; encouraging a wider usage of the service through product reviews, creation of wish lists, etc. Online retailers can also offer bundled services and features such as related item suggestions whenever a customer buys a product and offers of cheaper or even free postage for multiple purchases. Securing enough differential advantage might help in enhancing loyalty. On the other hand, E. Ghazali et al. as our findings indicate, availability of attractive alternatives is extremely important and is relevant to new start-ups seeking to challenge the more established retailers. Finally, in spite of the importance of constructing switching barriers, managers must be careful not to ‘lock-in’ their customers (Frow et al. 2011), as this may be seen as unfair conditions of a sale, leading to perceptions of unfairness, which may damage the brand (Nguyen et al. 2015). Hence, moderation to the developing of switching barriers as well as consideration of fairness from the consumers’ perspective is preferred to utilize switching barriers successfully. Limitations and future research While this study has focused on customer perceptions towards five unique switching cost dimensions in the context of pureplay e-retailers, future research could focus on the role of each of the five dimensions vis-à-vis loyalty, specifically, focusing on the importance placed by customers on each of the individual dimensions. Of particular interest would be to find out whether the influence of learning costs’ on loyalty would differ from that of artificial costs. One of the unique contributions of this research is that it focuses specifically on pure-play online retailers. However, most retailers have both an online and offline presence. As shown by Shankar et al. (2003), online loyalty does ‘transfer’ from the loyalty of traditional (offline) settings. Therefore, future research could compare between pure-players and bricks-and-click companies. Insights from these studies would be useful in shedding light on the role of perceived switching barriers as a retention tool. In addition, as our study was based solely in the UK where e-commerce is quite mature, further studies could examine the phenomenon in other countries/ groups of countries, which have different levels of Internet usage and/or are at different stages of economic development. Further studies could also explore the moderating influence of various demographic and psychographic characteristics such as age groups, income, family size, and social class. It should be noted that our study focuses on loyalty and we differentiate this from habit or inertia, which refers to behavior or activities performed repetitively, often unintentionally (Ji and Wood, 2007). Future studies should examine habit in terms of its measurement and effects on online customer retention. It would also be interesting to carry out longitudinal studies on how customer behavior on pure-play retailers, change over time as these retailers grow. Finally, given the importance of customer self-participation in value cocreation on the Internet (Mohd-Any et al. 2015), future research could investigate the associations between customers’ perceived value-in-use and their perceived switching costs. Investigations of the value-in-use concept from a servicedominant logic perspective could deliver significant insights and could result in an extension of our framework.
