These are web sites that provides an online community for people to congregate and share information on a variety of subjects. Members generally create an online Profile containing biographical data, pictures and personal information they wish to share. Most communication is in the form of keyboard data entry, for example, chat, forums and blogs but also might include more advance electronic communication like voice and even videoconferencing.

Several social network sites include topic areas for promoting and discussing product and service sales. ClassifiedFlyerAds includes access to the most popular of these sites on each flyer using the social network service user interface. Member flyers that have been added to social networks have both the advantage of increased viewership of their listing and, as important, increased page ranking possibilities on popular search engines like, Google and Yahoo.
