By linking Google Analytics and AdWords accounts, advertisers get a detailed picture of the performance of their ad creatives and keywords. “Manually optimizing campaigns works well for the top 100 or 1000 keywords, but can be a challenge for 1000+ keywords in the long tail. To help advertisers, we’re releasing 5 new dimensions through Google Analytics API that correlate to AdWords API IDs: ga:adwordsCustomerID, ga:adwordsCampaignID, ga:adwordsAdGroupID, ga:adwordsCriteriaID, and ga:adwordsCreativeID. This give advertisers new insight by combining data from Analytics and AdWords data sets. To get you started quickly, an article walks you through the steps of joining data from both sources. Also provided sample application that produces the table (see pic). Here's a sample Java code snippet that shows exactly how to insert the IDs from Analytics into a AdWords API filter. Please keep in mind that all applications that combine data with the AdWords API must follow AdWords API terms of service,” explains Google.
