Friday my CTR was X. Since then it has been X/4. The time period is short, I know, but this is over several thousand impressions and for some reason, my CTR has always gone up substantially during the weekend previously. As far as I can tell, the same ads are showing, but I'm only in one area. My biggest fear is that Google is showing car ads (same name as the location my site is about) to people not in my location. How can i find out without calling someone on the east coast?
