Yes and none of them are pleasant. It might be that Adsense has integrated that behaviour based advertising to such an extent that it thinks people are on holidays (or weekend break) and therefore it won't serve well targeted ads to sites that have a working week profile. As this is the traditional holiday season in Europe, every day seems like a holiday to them.
Does anyone have a theory as to why we are all seeing such dramatic drops in CTR and revenue?
