Yesterdays stats were shockingly poor! WTF happend. Today looks no better, so I decided to take some adsense advice I received from a real adsense employee. I only allow 2 ads per page, some only one. They reminded me that if the same ad size is used more than once on the same page, the second ad shows a lower bidder, so diversify. So lets say you run three ads, use the top 3 ad sizes so each ad shows the highest bidder for that ad size. I'm trying it with two ads, and if it improves, maybe a third on pages that won't look spammy.
