How can I troubleshoot duplicate pageviews in GA4?

Asked on Oct 05, 2025

Answer

Duplicate pageviews in GA4 can skew your data analysis, so it's important to identify and resolve the issue. Typically, this occurs due to incorrect tag setup or multiple tracking codes firing on the same page.

Sign in to your Google Analytics account.
Navigate to Admin → Data Streams and select your web data stream.
Check the "Measurement ID" to ensure only one instance is implemented on your site.
Use Google Tag Assistant or the GA Debugger extension to verify that only one pageview event is firing per page load.
Review your Google Tag Manager setup to ensure no duplicate tags are published.

Additional Comment:

Ensure that your GA4 configuration tag in Google Tag Manager is set to fire once per page.
Check your website's source code for multiple instances of the GA4 measurement ID.
Consider using the "Preview" mode in Google Tag Manager to test tag firing behavior before publishing changes.
Review any custom JavaScript that might trigger additional pageviews.
