Google said they've simplified the linking process between your Google AdSense accounts and Google Analytics reporting.
Google said "you can link your AdSense account within Google Analytics in fewer steps and can also link your AdSense account to multiple Google Analytics accounts."
This is the process to do it:
- Sign in to your Google Analytics account.
- Click the Admin tab at the top of the page.
- In the "Account" column, select the Analytics account that contains the property you want to link with your AdSense account.
- In the "Property" column, select the Analytics property you want to link, and click AdSense Linking.
- On the "AdSense Linking" page, click + New AdSense Link.
- Select the AdSense property that you want to link with your Analytics property.
- Click Continue.
- Select the Analytics views in which you want your AdSense data to be available.
- Click Enable Link.
- Click Done.
Your Analytics and AdSense accounts are now linked.
