they'll think you're generating false clicks. Aim for a ctr of about 1-5% (for every 100 impressions you get 5 clicks.)
I think what's happened is you've had 1000 Pageviews but somepeople clicked your ads multiple times so people have had had 1 impression but more than 1 click. If you got 1.5 clicks from 100 people it's fine but if you got 1400's clicks from one person and 100 from 999 people then it's click fraud. -Brennan
I think best you can aim is like 20% only in determined cases where people goes looking for very specific info, lands on very specific information but needs information even more specific and only way to get out of your page is through adsense ads.
ah ic.. thanx for the info, i just want to ask if they click different links in may ads.. its still be fraud? for example 1 person sufring my site and then he or she will click all the ads links on the page. 1 click per link, its still a fraud?
Normally your rate must be %0.8 - %7 but 1000 pageviews/1500 clicks incredible. Please be careful may be you get banned or down your rates. Regards, Mustafa
