“…The findings of Chen et al (2016) , Cheung and Thadani (2012) , and Abedi et al (2019) reported that electronic word of mouth in the form of user reviews, testimonials, descriptive sentences or articles written by customers, helpfulness rating, or electronic comments on the Internet can help customers gain confidence and conformity of the product, help customers set their expectations and attitudes before making a purchase decision, thus increase their purchase intention. These findings provide empirical evidence supporting the proposal that consumers are more likely to rely on eWOM sources before shopping; they use social information when making decisions, especially in uncertain situations ( Ardyan et al, 2021 ). These results also provided a strong motivation for companies to improve eWOM activities on their shopping websites and the Internet, which can educate and provide their customers with positive information in order to change customers’ perceptions and attitudes toward the usefulness of foreign functional foods.…”
