Just conducting a little survey. It seems some AS users suspect that the recent drop in earnings relates to SERPS. Anyone else noticing that the more your SERPS drop the less your EPC (earnings per click) is? Clicks: 25% more. CTR: No significant change. EPC: Noticeable drop. CPM: Noticeable drop.
Clicks: No significant change. CTR: No significant change. EPC: Noticeable drop. CPM: Noticeable drop. SERPs: Noticeable increase for some, flat for others. -- Derek
