Google Analytics

Integrate Google Analytics 4 and Google Tag Manager with Fern Docs. Complete setup instructions for tracking website traffic and insights.

Fern supports integrating with both Google Analytics 4 and Google Tag Manager.

Google Analytics 4

Before you begin, ensure you have a Google Analytics 4 property ID. This ID is typically in the format G-XXXXXXXXXX.

Add GA4 to `docs.yml`

Open your docs.yml file and add your Google Analytics 4 property ID under the measurement-id key:

docs.yml

1 analytics:
2   ga4:
3     measurement-id: G-12345678

You can optionally add the ID as an environment variable:

docs.yml

1 analytics:
2   ga4:
3     measurement-id: ${GA4_MEASUREMENT_ID} # scans for GA4_MEASUREMENT_ID environment variable

Verify your integration

Check your browser’s developer tools or the network tab to confirm that the analytics script is loading correctly. Note that it may take 24–48 hours for website traffic data to start appearing in Google Analytics.

Google Tag Manager

Before you begin, obtain a container ID from your Google Tag Manager account. This ID follows the format GTM-XXXXXX.

Add GTM to `docs.yml`

Open your docs.yml file and add your Google Tag Manager container ID under the container-id key:

docs.yml

1 analytics:
2   gtm:
3     container-id: GTM-NS32L7KR

You can optionally add the ID as an environment variable:

docs.yml

1 analytics:
2   gtm:
3     container-id: ${GTM_CONTAINER_ID} # scans for GTM_CONTAINER_ID environment variable

1	analytics:
2	ga4:
3	measurement-id: ${GA4_MEASUREMENT_ID} # scans for GA4_MEASUREMENT_ID environment variable
