Google released a new “View-through conversion reporting” on the Google Content Network, that let you easily compare the performance of your Google Content Network campaign with the performance of your other display advertising campaigns. This feature can also help you determine the best ways and places to advertise, how best to optimize your display ad campaigns, and, ultimately, how to spend your advertising dollars more effectively. You can also visit the Campaigns tab in AdWords and activate the optional View-through conversion reporting column. You’ll need to have AdWords Conversion Tracking installed for View-through conversion reporting to work for your campaigns.
