so i had somebody tell me my Campaigns (search, shopping and pmax) were not performing at optimum levels because my Google Tag is either incorrect or not installed correctly. They said if installed correctly, it provides feedback back to Google campaigns to help finding "my" audience. He said my conversions were sporatic because google has no feedback from our Site (?) Is this a possibility? I thought that why we sent Google Audiences and Signals and email lists etc.
Any feedback on this would be appreciated. I'm running out of tequila.
