Social media advertising is a form of online advertising 1 provides very targeted ads based 2 i nformation supplied by members of a social media service. While social media advertising has been hailed by some as a revolution in direct marketing, it has also brought 3 many privacy concerns. These concerns stem mostly from the distribution of member information acquired by third parties, such as applications and other platforms not created by the social media service itself. The first step in social media advertising is acquiring members by encouraging people to 4 up for a particular social medium, such as a social networking site like Facebook, MySpace or Twitter, a 5 sharing site such as YouTube, a photo sharing site such as Flickr, a blog, or even an email provider. These services will first 6 basic contact information from the member, such as his or her name, email address, or phone number. The service will then encourage the member to fill in other fields of information which may be purely 7 , such as age, gender, location, hobbies, and interests. The 8 information the member provides about him or herself, the more easily he or she is slotted into a specific demographic for data aggregation and subsequently, targeted social media advertising.

The social media service then 10 the member’s data with the particular demographic that their sponsors wish to target for products or services. 11 a result, a social media member who listed “bicycling” among his or her hobbies and “Kansas” as his or her 12 might then see ads appearing on the service’s website for a Kansas-based bicycle shop. The fewer details provided by the member in his or her information 13 , the less targeted the ads will be.

Although some social media members 15 social media advertising to be fairly benign if not welcome, the increase in social media use over the last decade has 16 concerns about information privacy. For example, sites such as Facebook allow outside application developers to 17 quizzes, s, and other accessories for members to use in exchange for 18 to their account information. As the restrictions and policies surrounding 19 outside developers then do with this information is relatively obscure, some are concerned that it may leave members vulnerable to 20 theft, spamming, and other illegal or non-ethical practices.
