Social network advertising, also social media targeting is a group of terms that are used to describe forms of online advertising that focus on social networking services. One of the major benefits of this type of advertising is that advertisers can take advantage of the users’ demographic information and target their ads appropriately. (Wikipedia)
Social network advertising is not necessarily the same as social media advertising. Social media targeting is a method of optimizing social media advertising by using profile data to deliver advertisements directly to individual users. Social media targeting refers to the process of matching social network users to target groups that have been specified by the advertiser.
Social media advertising helps businesses find new potential clients by using users’ own shared information to identify interest. Rather than reactively targeting users who search a certain term, social media advertising proactively targets relevant users before they even begin their search.
