Just found a cool script at http://www.adsenselogger.com. This script counts your adsense impressions and clicks! It also shows you which colors are the good ones. It also collects data from adsense to report the earnings.
So all I did is to create a plugin for this script…

ABOUT.
=================
This plugin installs the Adsense logger, inserts the corresponding javascript into the footer
and displays the reports within the admin interface. For statistics of your revenue, you have to
enter your adsense username and password in the configuration of adsense logger.
This adsense logger plugin uses the wordpress configured prefix for table creation for this logger.

from the original readme:
###################################################################
Note: If you do not feel secure by disclosing your adsense details,
simply leave them blank. If they are blank, no earnings tracking
will work, but all other stats works.

Your adsense username and password is NEVER transmitted home by the
script, and is ONLY used to get the latest stats from Google.

Dieses Plugin ist aktiv auf bundesliga-blog.de. Ich werde es noch eingehender testen, tunen und dann releasen.

So viel zu meinem ersten Ausflug in die Welt der Wordpress Plugin Erstellung.
Evtl. kommt ja bald mal wieder was. Vorher prüfe ich aber alle Namensrechte.

Ich bedanke mich hiermit bei den vielen Nutzern des Plugins, bitte sie aber gleichzeitig, das Plugin umgehend zu entfernen.

Weiterhin bedanke ich mich bei dem Namensinhaber und dessen Anwälten für die doch sehr nette Art und Weise mir das mitzuteilen. Andere hätten einen schon vor den Richter gezogen.

Vielen Dank!
