Online information research has been a popular pastime among consumers in recent years. The idea of word of mouth has regained popularity, just as social media, websites, blogs, and other online platforms have grown in popularity. It has been shown that information task-fit reduces specific but frequent information deficiencies for visitors. This study investigates purchase intentions by combining predictions from information features and consumers' information-related behaviours, and it proposes an information acceptance model in which an information task-fit is created to contribute to buying intention. This study surveyed 205 customers who used social media or web sites to find products through quantitative research. The result pointed out that the information characteristics as quality, credibility, and task-fit positively impact information usefulness, affecting purchase intention and information adoption. Besides, information adoption has a positive antecedent of purchase intention.
