Similar to Google’s AdWords and Analytics Certified Partner programs, individuals and companies can qualify to become a Google AdSense Certified Partner by passing the certification exam and meeting program requirements.
AdSense Certified Partners are qualified to manage dedicated services, everything from setting up AdSense ad code to running ongoing optimization tests. Once a company has passed the certification exam and meets all the program requirements, it will have access to AdSense marketing resources and tools, receive the Google AdSense Certified Partner badge to use on its website, as well as being listed on Google’s official AdSense website.
Google says it has comprehensive training and testing resources available for companies interested in joining the program. According to Google, there are currently 13 active Certified Partners.
