AdSense-Tips
Channels

Channels serve as a basis for reports.

They are definitely needed to produce meaningful reports. Google distinguishes between two different kinds of channels. You can configure and access them on your AdSense user area.

The first kind is called URL Channels.

URL channels are used to track the efficiency of one ore more pages of your website. The amount of pages analyzed depends on the given URL. Only a URL that leads to a single page will result in a report that relates to exactly one page. A partial URL will always result in a report about all pages available below this URL. As a consequence you can get a report about a complete website by specifying its top level domain.

Using URL channels the smallest reportable element is a single page of your website – not very helpful if you want to optimize your ads.

URL channels are useful if you want to get an overview about your whole website's success or if you want to compare the results of single pages.

Most of the time I use Custom Channels

to find out how successful my ads are, because only with these I can define exactly what information I need about which ad. I assign a separate channel to each ad block. This has the advantage, that I get detailed information how successful each ad on my website is. Only from this detailed information I'm able to learn which ad is successful or which one has to be changed, improved or deleted if it doesn't do it.
