The last few days my CTR has been down, where it normally is pretty stable. Checking the ads (I normally block them from being seen on my IP address) shows that the normal "Ads by Google" has been replaced with "Ads by Goooooogle".
I'm guessing that this may have attributed to the drop in CTR. Does anyone know what triggers this and/or how it can be changed back to the "Ads by Google"?
