Purpose: – Satisfaction and experience are essential ingredients for successful customer retention. This study aims to verify the moderating effect of experience on two types of relationships: the relationship of certain antecedents with satisfaction, and the relationship of satisfaction with intention to repurchase. Design/methodology/approach: – This paper applies structural equation modelling (SEM) and multi-group analysis to examine the moderating role of experience in a conceptual model estimating the intention to repurchase. Responses from 393 people were used to examine the differences between high- and low-experienced users of online shopping. Findings: – The research shows that experience has moderating effects on the relationships between performance expectancy and satisfaction and satisfaction and intention to repurchase. This study empirically demonstrates that prior customer experience strengthens the relationship between performance expectancy and satisfaction, while it weakens the relationship of satisfaction with intention to repurchase. Practical implications: – Practitioners should differentiate the way they treat their customers based on their level of experience. Specifically, the empirical research demonstrates that the expected performance of the online shopping experience (performance expectancy) affects satisfaction only on high-experienced customers. Instead, the effort needed to use online shopping (effort expectancy) and the user's belief in own abilities to use online shopping (self-efficacy) influence satisfaction only on low-experienced customers. The effect of trust and satisfaction is significant on online shopping behaviour on both high- and low-experienced customers. Originality/value: – This paper investigates how different levels of experience affect customers' satisfaction and online shopping behaviour. It is proved that experience moderates the effect of performance expectancy on satisfaction and the effect of satisfaction on intention to repurchase. It also demonstrates that certain effects (effort expectancy and performance expectancy) are valid for only one of the two examined groups, while only one effect (trust) is valid for both (high- and low-experienced).

Purpose: In the complex environments of online personalization, multiple factors have been considered to explain consumers’ online behaviour, but largely without considering the role of specific configurations of variables and how they may affect consumer behaviour. This study aims to show how trust towards online vendors, privacy, emotions and experience combine to predict consumers’ purchase intentions. Design/methodology/approach: Building on complexity theory, a conceptual model followed by research propositions is presented. The propositions are empirically validated through configurational analysis, using fuzzy-set qualitative comparative analysis (fsQCA) on 182 customers with experience in personalized online shopping. Predictive validity analysis is also performed. Findings: Five solutions of trust, privacy, emotions and experience increase intention to purchase, and six solutions inhibit it. The findings verify the importance of trust and happiness in successful personalized online shopping. Their absence inhibits purchase intentions. Also, high experience may help to overcome low trust or negative emotions, whereas low experience requires the combination of high trust and happiness. None of the examined factors are indispensable to explain purchase intentions. Research limitations/implications: The study uses fsQCA, differentiating from traditional studies in the area that use variance-based methods and identifies multiple solutions explaining the same outcome. The proposed approach contributes to theory development in the field. Practical implications: The multiple solutions lead to new ways on how companies may approach their customers, as each one covers a specific part of the sample, adding to the fact that in personalized marketing there is not one single optimal solution explaining customer purchase intentions. Originality/value: This study contributes by extending existing knowledge on how trust, privacy, emotions and experience combine to increase or mitigate intention to purchase towards the development of new emotion-centric theories and the design and provision of personalized services and presenting a step-by-step methodological approach for how to apply fsQCA in e-commerce studies.
