There are some recent, early complaints at WebmasterWorld on the AdWords (advertisers) side of things that the content ads they are running are not performing as well as they once did. Typically, you see AdSense publishers (those that host the content ads) complaining that they are not getting paid as well, but now you see advertisers complaining. Here are some complaints;
One of my biggest Content campaigns has been butchered in the last month....September Stats 110,000 CLICKS 0.10% CTR $0.45 AVG CPC 2.8 AVG POS.
October Stats (Nothing Changed) 55,000 CLICKS 0.10% CTR $0.59 AVG CPC 4.7 AVG POS.
I have taken about a $400 a day hit on my content network. I have made zero changes. Cant seem to figure out why the drop.
There are three different accounts for this change, can it be a real issue?

Maybe their competition changed, o the landing page was changed ...

Uh - the competitive environment changed. The Average Position dropped from 2.8 (where it will appear in most AdSense blocks) to 4.7, when it will only appear on properties with two blocks per page. Hence the drop in impressions. IOW - there's more competition in the space and someone else is taking your impressions. No news here, move along...
