Excerpt from: Don’t Waste Time on Google AdSense
The biggest advantage of offering placements in Google AdSense is that you can maximize your ad revenue. Google AdSense placements provide advertisers with the exact placements they seek for their ads, and in turn you can obtain premium pricing by giving advertisers what they want.
Placements in Google AdSense start with custom channels. Custom channels allow you to track the performance of specific ad units based on your specified criteria, such as ad formats, ad positioning, or topics. For example, you can create a channel for ads that pertain to a specific topic, such as Google AdSense related products. You can also create a channel for ad units that appear at the top of each page or on the homepage. And you can also create a channel for only image ads, only video ads, etc. In all, Google AdSense provides you up to 200 channels to customize.
What’s more, you can turn any custom channel into an ad placement on which advertisers can choose to place their ads, meaning you can generate ad revenue by giving advertisers exactly what they want. When you create ad placements out of your channels in Google AdSense, advertisers can target their ads by topic channels or by position on your webpage or website. The greater the placement options you offer advertisers, the more competition for your available ad space and the more ad revenue you will generate.
