Since many of the complaints last year around how AMP and Google Analytics don't really work well together, Google has been working on improving the accuracy of how Google Analytics tracks sites with AMP pages.
Google announced a new solution that will do just that but it requires a "small code change" on both your AMP and non-AMP pages.
If you make this change, Google said you can expect that your user and session metrics will drop down to more accurate counts as formerly distinct users are recognized as the same person, as well as related metrics that will also become more accurate (such as Time on Site and Bounce Rate). And New Users may rise temporarily, Google added.
Here is what you need to change:
Opt in on your AMP pages
Include the following code in the <head> of your AMP page:
<meta name="amp-google-client-id-api" content="googleanalytics">
Opt in on your non-AMP pages
Google Tag Manager
The following steps should be completed on your existing published tag container(s).
- Navigate to Tag Configuration > Fields to Set.
- Set
useAmpClientIdto true. - Save the new tag configuration.
- Submit the tag.
- Publish the container.
analytics.js
Include the following in your Analytics tracking code:
ga('create', 'UA-XXXXX-Y', 'auto', {'useAmpClientId': true});
