Are Firefox Referrals impressions and clicks included in the Ad Performance Reports? If I check my stats for this month, I have X page impresions selecting all of my channels. But if I check Aggregate Data, the page impressions double and clicks raise in a figure similar to my Referrals Clicks. My first thought was that someone was using my Adsense Code in their own site (I already wrote to Google, just in case) but the consistence of the data made me check deeper. If effectively Firefox Referrals are taken into account to determine the overall account CTR, then I have a problem and I will opt for removing the Referrals code.
I disabled the Firefox Referral button in half of my site. If the impressions decline in proportion, then this is the problem. If not, my site was scraped with the Adsense Code (and the scrapers removed the channel code?). Any other idea?
Checking back my daily statistics, I found out that the difference between Channel Data totals and Aggregate Data started exactly the day I tried Firefox Referral Program for the first time. So I believe those Firefox buttons are being accounted as Page Impressions, impacting severely my CTR. It should not be this way.
I just removed all referral buttons. I don't want to be penalized because I show an apparent very low CTR. I will wait until this issue is solved before I try Referrals again.
