Checked my stats today. Notice I have 25 clicks on 25 impressions. Is this for real or a glitch. No way did everyone click on an ad... is there?
Quite possible, a curious person may click on your ads and then go back and keep clicking, once I had one visitor = 10 clicks = $5 on a one page new domain, needless to say I had words as I knew who it was, but his actions were natural.
I have had 100% CTR several times. Its not that uncommon. Somebody comes to the site and thinks it sucks and they simply look for a way out. If the first link they see is a adsense link they click it. Unless you see it happening everyday with lots of clicks (not 1-2) then I wouldn't worry to much. Google is not stupid they know what faud click looks like and what it looks like when somebody just wants to get off that website.
Ironically, when I checked my adsense account awhile ago, I saw 1 page impression, 1 click but 100% ctr. How's that? Lol..
well once my blog got 200% , 6 clicks for 3 impressions tough i reported to google as invalid cick activity
Got enemies? Click bombing is nice and easily placed here, though it's a little too little clicks for a bombing.
