In my experience, for good quality sites, it's absolutely nothing to do with advertising.
The old ways to rank a website are now obsolete.
I think Panda penalized your site because your site did not generate enough quality signals.
This is the bizarre part, just what is it they are looking for? I have a widget trade directory that has been hit, I have widget trade B&M sites mostly unscathed HOWEVER I am constructing a new site using all my established methods and some of these pages are now actually out-ranking better pages of mine on other .tld sites!
As a widget trade professional of 40+ years I know which are the better pages yet Google's algo deems to judge otherwise.
The advertising positioning on all sites is precisely the same.
