Exclude Unwanted Query Parameters to Analyze '(Other)' Impact in GA4 Reports.

To minimize the impact of '(Other)' in GA4 reports, you can remove all unwanted query parameters from your page path before sending the page tracking data to GA4. This involves identifying query parameters that do not change the content of a web page and excluding them from your reports to prevent multiple entries for the same page.

URL query parameters that do not change the contents of a web page should be excluded from GA4 reports to avoid having multiple entries for the same page. This is important because GA4 does not have a built-in feature to exclude URL query parameters, and failing to do so can lead to high cardinality dimensions, which in turn can cause the '(other)' category to appear in the reports.

You should not exclude the following query parameters from your GA4 reports:

• Search query parameters
• gclid
• gclsrc
• dclid
• gclsrc
• srsltid
• utm parameters These parameters are typically important for tracking marketing and referral information.

To remove URL query parameters in GA4 using Google Tag Manager (GTM), follow these steps:

1. Get a list of non-content changing query parameters from your web developer.
2. Decide which query parameters to exclude from GA4 reports.
3. Decide which query parameters to keep.
4. Login to GTM and import the 'Query Parameter Stripping Utility' variable template.
5. Create a new user-defined variable with the template, entering the parameters to keep and setting the {{Page URL}} as the field to remove parameters from.
6. Edit the GA4 configuration tag to set the 'page_location' field to the new variable {{Exclude query parameters}}.
7. Save the tag, preview, and publish your GTM container.
