Change the primary property for an AdSense account in Analytics

Your primary property is the property to which you don't need to add any code to enable integrated AdSense-Analytics reporting. Webpages on your primary property only need to have the AdSense ad code to show ads and the Analytics tracking code to enable integrated reporting. Webpages on other properties need AdSense code, Analytics tracking code, and the AdSense Analytics code (ASAC) to enable integrated reporting.

To change your primary property:

  1. Sign in to the Analytics account you've linked to AdSense.
  2. Click the Admin tab.
  3. In the "Account" column, select your AdSense account.
  4. Click AdSense linking
  5. Click Make Primary for the domain you want to serve as your primary domain.
  6. Click Switch.

Once you’ve changed your primary property, you need to add the ASAC to all pages on the new secondary property. Previously, when these pages were on the primary property, they didn’t require the ASAC, but now that they are on a non-primary property they do require the ASAC.
