Most of the times publishers tend to loose their Adsense Accounts either due to sabotage from rivals or clicking on their own ads.
Clicking on your own ads has no excuse, but what to do if someone sabotages you ??
If guys there at Adsense see about 10–20 invalid clicks in your Adsense account, You will be straight away throw you out of Adsense. And their is very little hope that your your appeal will be considered. So to be on the safer side, you must have your own invalid click tracker.
Wordpress Bloggers are lucky because there is a plugin called Adsense Logger which does the job of tracking invalid clicks. Apart from tracking invalid clicks it also:
How to Install this plugin ?
- Get Adsense Logger
- Upload adsenselogger.php and the directory adsenselogger into your plugins directory of your wordpress installation
- Chmod count.php and countimp.php to 0644.
- Make sure that you Chmod config.php to 0644.
- Activate the adsense logger plugin in your plugin administration
- Go to adsense logger in the dashboard and enter username and password (if wanted)
How to Report a Invalid Click ?
Collect as much data as possible (Date, IP, Time, Page etc) and report it to adsense here
And you will receive a reply like:

That is a very informative article. I am sure, bloggers who use WordPress and Adsense would find this post very useful.
I though, have started to use Drupal as the CMS, and I assume, there is a similar module for tracking clicks in Drupal too.
