I recently added AdSense ads to a few blogs...used the "add a feature" button on the Blogspot template to quickly add Adsense.
But all the clicks are grouped into one category...not broken down by blog.
Is there anyway to enter the code so it keeps tracks of clicks by blog? I know you can do this with websites by setting up channels, but I don't see an option like that for Blogspot.
As you already know you can create custom channels for websites. But since you're displaying adsense in Blogger and there is no way to do it through Blogger set up a custom url channel in your account under channels to track the performance by url.
But I would recommend that you do the custom channels through Adsense because with you add it through Blogger it only displays text link ads. If you do a custom channel you have the option of having text/image and of setting up the fill color for when non relevant ads can be displayed.
