Researchers say Google’s ad-targeting system sometimes makes troubling decisions based on data about gender and other personal characteristics. Researchers Investigate Google's Ad System With AdFisher, Ad Targetting Tool [technologyreview.com]
Researchers from Carnegie Mellon University and the International Computer Science Institute built a tool called AdFisher to probe the targeting of ads served up by Google on third-party websites. They found that fake Web users believed by Google to be male job seekers were much more likely than equivalent female job seekers to be shown a pair of ads for high-paying executive jobs when they later visited a news website.
AdFisher also showed that a Google transparency tool called “ads settings,” which lets you view and edit the “interests” the company has inferred for you, does not always reflect potentially sensitive information being used to target you. Browsing sites aimed at people with substance abuse problems, for example, triggered a rash of ads for rehab programs, but there was no change to Google’s transparency page.
What exactly caused those specific patterns is unclear, because Google’s ad-serving system is very complex.
