Just wanted to know if leaving the option “Conversion Measurement” active in the official Google & YouTube App can disturb the data collection to Google Ads managed through a normal sGTM setup. I left it active because the client is using the Google & YouTube app to sync the product feed with the Merchant Center, and I am frightened that turning it off can cause a problem with e.g. free listings or worse deactivate the Merchant API flow. As you can see in the screenshot, the only active Google Tag is the one sending data to the Merchant Center (it’s in German sorry).
Your current setup is completely safe and should not cause any overreporting. You can continue using the Google & YouTube app to sync products with Merchant Center.
As long as you haven’t configured GA4 tracking through the app or enabled Google ADS Conversion Measurement for the conversions that are already being tracked through sGTM, everything is fine.
