I've noticed a trend in the last month or so with YPN. The ads have become less and less targeted towards my site and my CTR has dropped (.03-.05) . But my CPM is through the roof. Over the last 2 weeks it's in the $15 area. Ads are much less targeted but the ads that are showing are much higher paying. Really would prefer to show more targeted ads but i'm currently receiving more revenue than ever. Anyone else seeing a trend similiar to this? Is is best to ride it out til my CPM returns to normal (for me around $2) than try and use ad targeting? What would you do in the same situation?
