In the context of online shopping, websites play a critical role in facilitating transactions between buyers and sellers. An online store's website acts as a focal point for a company's online identity and encompasses not only the products and services offered but also the company's aesthetic image and values. Creating a strong online identity helps an online store differentiate itself from competitors, attract and retain customers to strengthen its competitive advantage, and improve brand, product, or service differentiation. On the other hand, understanding the repeat purchase intention of consumers is essential for maintaining growth in this business. This research, by providing a new theoretical perspective for understanding the online shopping behavior of committed customers, shows that a store's website creates a specific identity that itself affects the repeat purchase intention. The present study examines the factors affecting website cultural identity and the repeat purchase intention by testing a conceptual model by King et al. (2016) in order to develop the model. Based on the information gathered from 463 customers of online stores in Tehran, including a segment of students of Islamic Azad University, Science and Research Branch, the results of this research showed that increasing product attractiveness, service attractiveness, customer e-satisfaction, fulfillment, website cultural identity, and website attractiveness leads to an increase in the repeat purchase intention. Increasing website trustworthiness, product attractiveness, service attractiveness, and website attractiveness leads to an increase in website cultural identity. Increasing website attractiveness and fulfillment leads to an increase in customer e-satisfaction. However, increasing website trustworthiness does not lead to an increase in the repeat purchase intention. The results can be a basis for online stores to understand and use website cultural identity as a new strategy for attracting and retaining customers with a focus on the repeat purchase intention.
