When friends recommend a group that concerns a company, the receiver is much more likely to join that group too, since friends often have similar interests (Diffley, et al., 2011). When consumers see pictures of products on their friends’ profiles, they might purchase that product, if it has made a good impression on them (Cheong & Morrison, 2008). Consumers’ attitudes towards products and companies can be shaped by friends on SNS, if their comments are posted about a specific company or product, since friends share similar interests and are perceived to be trustworthy (Diffley, et al., 2011). If someone positively recommends or negatively evaluates a product to another friend, it impacts their behaviour towards the product (Ibid). In the research by Smith (2007), it was found that consumers, who had many contacts in their networks, were more likely to be influenced by others and follow their advice about products.
