I really fell puzzled, the CTR is quite stable, but CPC is 1c or 20c some times. Is there an issue with my site, or just Google dancing?
Up and down, but more on the downside. 10 day trailing average is from $8 to now $2 CPM. I don't know if anything I can do. I understand there is fluctuations but from average 1c to 20c CPC, that is really really wild. I am using images/text and banner, big ad unit. And there is no publi ads shown, always plenty advertisers, when I navigate the ads.
