Adsense Logger is an open source PHP script that helps website owners to optimize Google Adsense for their sites. I just found out about it today and realized that I wanted something like this for a long time, but never took the time to find it.
Apparently, there is an excellent plugin for WordPress that automatically installs and configures Adsense Logger to work with WordPress. Simply copy the files from the ZIP archive and assign correct permissions. TADA! You’re done. If you wish to see your Google reports within your WordPress administration area, enter your username and password in the plugin configuration page.
I’ve just installed and tried it and looks really good. Now all I am missing are those ad clicks (hint, hint, hint).
