Understanding Google AdSense (Part 3)
Channels
Google recently introduced channels, enhancing AdSense reporting. When a channel is selected Google modifies the java script to include additional tracking. The additional tracking information allows webmasters to track a variety of metrics across their sites. Channels can be used to measure performance on various domains, differences in revenue with various ad sizes, or placement. By assigning each group of pages to a specific channel and comparing results in custom channel reports webmasters can work at increasing their AdSense revenue.
Optimizing
Google determines the content of the ads that are shown, webmasters serious about earning revenue from Google AdSense can use the following guidelines to optimize their website and ensure that targeted and relevant ads are served. If Google’s spider has not crawled the site and determined the nature of the content, public service ads may be served. Public service ads will not accrue any AdSense revenue if clicked. As a result Google allows webmasters to designate alternate ads. Alternate ads allow webmasters to utilize the ad space in the event that Google is unable to serve targeted ads to the web page. By specifying an alternate image, HTML page, or ad server the advertising space can always being used effectively.
