Social Media websites allow individuals to interact with one another and build relationships. When companies join the social channels, consumers can interact with them and they can communicate with consumers directly. That interaction feels more personal to users than traditional methods of strictly outbound marketing & advertising.
Social networking sites and blogs allow individual followers to “retweet” or “repost” comments made by the product being promoted. By repeating the message, all of the users connections are able to see the message, therefore reaching more people. Social networking sites act as word of mouth. Because the information about the product is being put out there and is getting repeated, more traffic is brought to the product or company.
Through social networking sites, companies can interact with individual followers. This personal interaction can instill a feeling of loyalty into followers and potential customers.
