Resumen: Purpose: This paper aims to analyse the effect of technology acceptance variables on customer attitude and customer engagement behaviours (CEB) with social tourism websites (STWs). Design/methodology/approach: An empirical study was carried out with 346 customers. A model was developed to analyse the relationships between CEB and their determinants. Partial least squares – structural equation modelling was used to test the model. Findings: Customers’ perceptions of enjoyment, ease of use, usefulness and trustworthiness positively influence their attitude towards STWs and their subsequent engagement behaviours [purchases, word of mouth (WOM) and referrals]. Originality/value: This study develops and empirically tests a model that analyses the impact of technology acceptance model variables on CEB, both transactional (customer purchases) and non-transactional (customer WOM, referrals and feedback), in the context of STWs.
