Google gave AdSense publishers a new tool today - you can now track your earnings via URL and you don't have to paste any code into your existing pages to do it - awesome.

To track an entire site, just enter your domain like this:  yourdomain.com

To track just one directory on your site, enter your domain like this:  yourdomain.com/directory-to-track

You can even go down to the page level if you want to:  yourdomain.com/directory-to-track/pageONE.html

Remember, you don't have to modify the javascript code on all of your pages to track this way - this is the best part of these URL trackers...

To set this all up, login to your AdSense front page, click on "Ad Settings", then click on "Channels" - the top section of this page is new and contains the URL Channel setup area.
