How To Link A GA4 Property To Google Ads

1. Sign in to your Google Ads account.
2. Click the tools icon in the upper right corner of your account.
3. Under “Setup”, click Linked accounts.
4. Under “From Google,” find “Google Analytics (GA4) and Firebase”, then click Details. If you have “Edit” access to Google Analytics 4 properties, a table that shows all available properties and projects appears.
5. Find a Google Analytics 4 property in the table, then click Link.
6. In the confirmation window, click Link.
7. (Optional) To import site metrics from a linked Google Analytics 4 property, click Activate under the “App and web metrics” column (the Activate button takes about 5 minutes [but may sometimes be delayed by a few hours] to be available after linking the property).
   • This property will be used to show site engagement metrics in the Google Analytics reporting columns of your account. Note that you’ll need to add Google Analytics 4 columns to your Google Ads reports, these are distinct from UA metrics and are labeled as (GA4) in the metric picker.
   • In most cases, it will take less than an hour for Google Analytics data to be imported, but the process may take longer for larger accounts. Once the data is imported, you can add Google Analytics columns to your Google Ads reports.
8. In the confirmation window, click Activate.
