Summary

Setting up a GA4 test property can be done quickly by extending your existing Google tag to another Google product account. This underutilized method allows users to test new GA4 features or GTM settings on the test property before enabling them on the production property. It also ensures the tag's configuration is shared across all connected destinations, removing the need for manual duplication. The full steps for the setup are in the post.
