Joining it with Google Analytics data to create a fuller picture of the user journey. Here are some limitations to be mindful of when extracting and analyzing PMax performance data within and outside the Google Ads interface.

For starters, you will not see PMax data fall under the default Paid Search channel grouping but a separate grouping called Cross Channel containing PMax and Smart Shopping campaign data. For example, while some basic reporting templates are within the platform for PMax campaigns, advertisers cannot customize any reports or create custom metrics.
