Google has enhanced the new custom targeting channels for the AdSense publishers. With the new option, the AdSense users will be allowed labeling different ad units on their site, and the AdWords advertisers will be allowed to see the units and select them for their advertisements.

Publishers will be required to turn on the feature for relevant custom channel in the account, or establish brand new custom channels, making the site or ad units easy in ways the advertisers want to target.

Advertisers can also access the information of the channel for particular publishers to choose and select the target on the site.
