1. Create a Google login and a Google AdWords account, if you do not already have one.
2. Link your Google AdWords and Google Analytics accounts. Log in to Google AdWords and click the 'Analytics' tab. Complete the form to either sign up for a new Google Analytics account, or use an existing account.
3. Decide whether or not to allow 'auto-tagging' and to have cost data imported. Once your accounts are linked, allowing auto-tagging lets Google automatically tag and track your AdWords links. Allowing cost importing lets Google create return on investment (ROI) data for your AdWords campaigns.
4. Access your Google Analytics account, after you have linked your accounts either from the Google Analytics home page, or from the 'Analytics' tab within your Google AdWords account.
