How Does Google Adsense Monitor Clicks for Invalid Clicks?

1. IP Address Checking

   • Every time you log in to your Google Adsense account to edit your information or check your site's statistics, Google records the IP address of the computer you are using. Then, if a high number of ad clicks come from the same IP address, Google will usually flag your Adsense account since there is evidence that you are clicking on your own site's ads. Even if you log out of your Adsense account before clicking on ads, your IP address does not change and Google will likely consider all clicks from that IP address as invalid.
     

   Internet Cookies

   • When you click on an advertisement hosted by Google Adsense, an Internet cookie is placed on your computer to track your activity on the advertised site. As a result, Google can use the cookie information to see if you are clicking on a high number of ads or clicking on the same ad multiple times. If this is the case, Google will usually mark those clicks as invalid.
     

   Click-Through-Rate

   • Each Google Adsense advertisement that you place on your website tracks two different statistics: page impressions and clicks. Every time a page with an Adsense ad is loaded or reloaded in a web browser, another page impression is counted. A click is only recorded when a web visitor actually clicks on the advertisement and views the associated page. The click-through-rate is determined by dividing the number of clicks by the number of page impressions. If Google finds that your pages have an abnormally high click-through rate (usually more than 10 percent), your account may be flagged and checked for invalid clicks.
