Just like with Google AdWords and Google Analytics, Google has now introduced a certified partner program for AdSense.
The program details are at google.com/adsense/start/partners.
In short, it is not made for individual publishers but rather companies or individuals who can help publishers install, configure, monetize, optimize and improve their AdSense earnings.
Google said:
AdSense Certified Partners are carefully vetted by Google, and meet rigorous qualification standards. AdSense Certified Partners can assist with dedicated services ranging from setting up AdSense ad code on your pages to running ongoing optimization tests for you.
Google added:
For service providers interested in this new program, we’ve put together comprehensive training and testing resources that cover all aspects of AdSense. Once a company has passed our qualification exam and met additional criteria to become a Certified Partner, they’ll be added to our official program website and receive a program logo for their own site. Certified Partners will also have access to marketing resources and tools to help them manage client accounts, and will join a group of accredited companies. We currently have 13 active Certified Partners, and will be adding more to the list throughout the year.
I am just waiting for the day Google has a certified SEO partner program.
