At a recent “The Parliament and the Internet” conference, Andy Smith, an Internet security chief at the British Cabinet Office, encouraged people to give their personal information only to trusted websites, and to give fake details to social networking sites. This, of course, is a cause for concern for advertisers and the accuracy of their targeted ads. “Search engines and some retargeting display ad strategies rely on intent data from clicks and searches, but social media ad targeting starts by tapping information in profiles. Depending on the widespread use of fake information in profiles, it should make marketers rethink ways to determine whether all impressions are valid.” (MediaPost)
