  • Troubleshooting Data Traffic Across Multiple Properties in GA4

    Hey, I’m having a bit of a mess with my ga4 account. I’ve got 6 properties all lumped together. I’ve installed GTM and added it to the site. But, for whatever reason, one property’s page-view data shows up in the reports of all the properties. I remember there used to be a filter for this in GAU, but I can’t find the same thing in GA4. I tried adding a new domain in the data flow tab but that didn’t do anything. I even tried creating entirely new properties and still no luck. Any ideas on how I can fix this? It’s weird to see data traffic from other properties in my Google Analytics account especially when I set each property up separately. Think it could have something to with using the same GTM account?

    It sounds like you’re experiencing cross-contamination of your GA4 data. This is often a result of mistakenly sending the data from one website to another analytics property. Since you’re using Google Tag Manager, check that each property ID is correctly assigned in each GTM container. This would be the first thing I’d look at given that you’ve mentioned the issue still persists even when creating new properties. You might also want to consider using separate GTM containers for each of your websites to better manage the tags and analytics related to each specific site. This can also make debugging easier if you face any problems in the future.

    It sounds like the problem could be arising from setting up the Google Tag Manager (GTM) incorrectly for your properties. In GA4, each property should have its own distinct ‘Measurement ID’, which should be used in your GTM tag for each corresponding website. If you are using the same GTM container for all properties, you may be inadvertently firing all tags across all sites, which would cause all properties to record all the data, regardless of origin. To negate this issue, ensure each property tag in your GTM is triggering only on its assigned domain. Adding a new domain in the data flow tab or creating new properties won’t solve this problem if the underlying issue is with your GTM setup. Check your GTM container and the firing rules for your GA4 tags. It’s crucial to ensure that each tag is assigned to fire only on the appropriate domain.
