It's all relative

Revenue Science has filed a patent that will take it a step beyond the behavioral targeting network model, into a platform that connects advertisers with publishers, according to ClickZ.

The patent allows Revenue Science to serve behaviorally targeted ads to the highest bidding advertisers.

Revenue Science tracks users that visit its 4,000-site-strong network, in addition to non-network sites, to determine what users might be in the market for.

When a user in a desired audience enters its network, the user is recognized by the ad serving platform and served an ad based on previous interactions with the site.

Revenue Science's network attracts 120 million unique visitors per month.
