What it does:
This script monitors Performance Max campaigns across multiple Google Ads accounts under an MCC. It checks if these campaigns served in Google Shopping the previous day and checks if their spend meets a specified threshold. If any campaigns do not meet these criteria, the script sends a warning via email.
Why you care:
For most advertisers running PMax campaigns, clicks from the Shopping PLAs are the main revenue driver. Spending the budget on other channels like Display and YouTube mostly tanks results. If, for some reason (*), PMax stops generating clicks from Shopping and/or starts spending much more on Display or YouTube, you want to be in the know.
(*): potential reasons for PMax dramatically shifting spend to non-Shopping channels:
-
- Main products go out of stock
- Main products get disapproved
- Settings mistakes:
- wrong exclusion settings in productgroups (ie: custom label filters),
- too low/high ROAS targets
- budget too high
- Sudden change in actual ROAS performance due to
- Sale promotions
- Seasonality
- Competitor pricing
- Increased brand traffic
- Google’s greed to make more $$$
Why I like it:
This script will help you monitor PMax behavior and make sure performance stays on par. It is another great example of how I like to use scripts to Keep an Eye on Google’s AI.
