One of the many great features offered in adsense is channels. Channels allows you to see your earnings from a particular website or ad unit. Here are
a few examples of how you can put channels to work for you:
If you have multiple websites that you place adsense onto, you can set up channels so that you can see how much revenue each site is earning. This
can be very helpful as you can easily see which of your website are solid performers, and which of your websites are the poor performers
Another place whereby you can take advance of channels is by ad unit. Say for example that you have several sites, all displaying different ad units.
It can be difficult to learn which ad unit is the most effective if you are only looking at data for the overall website. So, if you have channels set up
to show you how each ad unit is performing, you can then understand how much income each respective ad unit is resulting in. You can then use this date to
further optimize your placements to try and maximize your adsense income.
