Data & Insights
Spend by Channel
Track actual and percentage spend across shopping, video, display, and search/other channels. See how spend distribution changes over time and how those changes affect performance.
Search Categories
Search categories are categorized into four buckets based on brand terms you define: brand, close-to-brand, non-brand, and blank (similar to ‘other terms’ in search query reports).
The sheet includes a link to the Google PMax Exclusions form if you need to request category exclusions.
Product Matrix
Products are categorized into six buckets: zombies, zero conv, meh, flukes, costly, and profitable. The categorization works across PMax and Shopping campaigns, with a sortable table showing which products are your best and worst performers.
Product ID Buckets
Create a supplemental feed for Merchant Center using the product bucket classifications. The sheet can link to your PMax data and update daily if you schedule it.
Placements
See which websites, YouTube channels, and mobile apps your PMax ads appear on. By default, placements spending more than 10 cents per day are shown (configurable). Use the Exclusions form to request changes based on placement performance.
Change History
All change history data in one place alongside your performance data. Includes a ChatGPT prompt for interpreting the raw change data.
Assets
Track which videos get the most spend and whether they're your videos or auto-generated by Google. Video assets include thumbnails and clickable links. Display asset stats and images are also available.
Asset Groups
Asset Group performance metrics including spend, clicks, conversions, ROAS, and AOV (average order value from Shopping Ads only).
Lead Gen Support
As of v52, the script supports accounts without product feeds. A ‘leadgen’ setting hides product-focused reports and switches to CPA instead of ROAS.
Requirements
The PMax Script works with individual Google Ads accounts (not MCC or Manager Accounts - there's a separate MCC version).
- Standard or Admin access to the Google Ads account
- Same email for Google Ads and Google Sheets
- 1-30 minute runtime depending on account size (setting available for large accounts to prevent timeout)
The script has been tested with accounts containing over 6,000,000 products.
