Today, i got 12 clicks on one of my blogs for just 7 page impressions which means that someone clicked more than once on my adds. I have heard that if someone clicks quite a few times on your adds you get banned for that. What you say, should i contact to adsense team about this or is it ok.
Hmm, I think you should be fine, as long as it's a one time event and that the clicks don't come from around your area. If you feel maybe a little iffy, there is no harm done in telling Google about it. EDIT: Actualy Contact just to be safe mate.
Use some sort of statcounter. I use www.statcounter.com But there are many different types of statcounters.
google adsense optimize your click by 2 way 01. valid click 02. invalid click i think your most of the click are invalid.
