Recently, the Google Analytics engineering team added the ability to allow you to link your Google Analytics account to your AdWords account:
Just log in to your AdWords account at https://adwords.google.com and click the Analytics tab. Then:
- Click I already have an Analytics account
- Enter the email address and password for your Google Analytics account. Note that you must be an Account Administrator on that account to be able to link it to AdWords
- Click Link Account
That’s it! Your two accounts are now linked, and Analytics will start automatically tagging your AdWords links for detailed campaign tracking reports.
