Might be a conspiracy theory of sorts...
Has anyone who had the same adsense code (owner id) across multiple sites have some sites hit by Panda, while others were unaffected by Panda?
I say ask this because I'm wondering if I should use a different ad rep.s on new sites I create instead of adsense. I hear some chatter about same owners being affected over multiple niches.
I just wondering if Google is trying to pattern or identify same site authors and give them a boost or penalty based on other work.
