YPN and adSense ads on the same site

but on different pages

[vitaly]

I started random delivery of YPN and adsense ads on my site (Y has been historically outperforming G for that site). I.E. every time a page is loading adserver puts either adsense or YPN code on it.

After several days of such mix serving CTR and CPM for adsense has decreased about 3 times. Has anybody experienced something like this?

Maybe add both Yahoo and Adsense is not allowed

Welcome to the forum goklik.

I checked, everything I do is OK with both G and Y
