This is a hub that describes how to link your Google adsense account with your Google analytics account. The result of doing this is being able to track adsense clicks Through Google analytics. You'll be able to track such things as:

• Top adsense earning hubs
• Top adsense earning referrers
• Your adsense revenue per 1000 impressions
• CTR (adsense Click-Through-Rate) 
• Your adsense eCPM
• ... and lot's of other intersting stats

Once activated the Google adsense tab appears under the Content section of Google analytics. You can also get ad sense data relative to other statistics in Google analytics such as adsense clicks based on region or user profile. 

Linking your Google analytics account and adsense accounts together is a manual process at the moment because this feature is in beta testing. I'm not sure if all requests are approved. I applied last year and my request was approved within one week.

1. Fill out the request form -- this is an official document from Google
2. 1-2 weeks later an e-mail should arrive with further instructions.
3. IMPORTANT - upon logging in Google asks to choose one website profile to use as the "main" one. Choose HubPages.

You can track adsense on an unlimited number of websites but that main site must be HubPages. The reason for this is that an extra piece of code is required on each website to enable adsense tracking except for the "main" site. The main site can use the old code. Since Hub Pages does not support adsense tracking (as far as I know) it's important to choose "Hub Pages" as the main adsense site so that adsense data is still recorded.

I hope that makes some sense. Further instruction and details are given during the three steps listed above. It's all quite a simple process and Google claims that all analytics accounts will have native support for adsense in the near future.

But I decided to write this Hub for us impatient ones. :)
