Yahoo Testing Behavior Targeting Of Ads

Spotted via InsideGoogle, Yahoo Tests Behavior-Based Content Ads from AdWeek covers Yahoo testing ad placement on web pages outside of Yahoo own site through behavioral tracking, in a partnership with Revenue Science. It's not clear how the system works. It could be that someone is considered interested in a topic like "cars" based on their surfing habits to car web sites, which might result in them being shown paid listings being targeted to that word. Alternatively, Revenue Science could be making use of Yahoo search data and delivering ads based on what someone has recently search for at Yahoo, similar to what AlmondNet does.
