I've been averaging 5-7 % overall CTR on my site. Since late December, I have been receiving traffic to one specific page, and it has around 30% CTR. Unfortunately, the ads on that page are rather low paying. I also noticed that the overall site earnings dropped by around 20% since late December. Is this drop in earnings in any way related to the high CTR on one page? Or is the earning drop being experienced by others too?
I can't see how, if 1 page on your website gets a good CTR, it'll effect the earnings of other pages of your websites? :/ So no.
I think the low click price and earning diminution are normal in the holiday season, people are on vocation now.
