Flaws in YPN's current algo
Flaws in YPN's algo

The current contextual algo is not giving enough weight to the title tags, h1 (et al) tags and other such indicators of what a page is truely about, this allows for a single string to dominate the evaluation of context.

In my limited testing of YPN ads (not on properties I own) the ads were too easily dominated by a single term. The whole page could be about poetry (or some other low-end niche) and a single mention of a larger niche (not necessarily a higher paying one) would dominate the ad serving.

This will need to be addressed before it goes live or the CTR won't be as good as AdSense.
