To track ads with this plugin you need to do the following:
Log in to Google Adsense
Click the ‘My Ads’ tab
Under content click URL Channels
Click the +New URL Channel
Add details of your site and you should start seeing data come in.
Obviously you need to have added your publisher ID into the plugin first.
I haven’t fully tested the functionality and amount of data that can be received using this method, but seems to work ok so far.
