Mike Rhodes PMAx Insights
A Google Ads script that extracts Performance Max asset, channel and product signals into Google Sheets for investigative reporting and analysis.
What it does
Mike Rhodes PMAx Insights is a Google Ads script used by advertisers and analysts to pull more granular Performance Max (PMax) signals into Google Sheets for investigation, comparison and ongoing monitoring. Asset-group and asset-level performance The script extracts asset-group and individual asset metrics from PMax campaigns and organizes them into tables and charts in a workbook. Users review these outputs to compare creative performance across asset groups and decide which assets to refresh or reassign. Channel and spend breakout PMAx Insights attempts to infer channel-level allocations (Shopping, Search, Display, Video/YouTube) from PMax activity and surface spend and conversion splits. This breakout helps teams investigate whether expected channels are serving and where budget appears to be allocated. Product-level matrix and feed mapping For retail or catalog advertisers the script maps product IDs or feed items into reports so you can inspect product-level contribution inside PMax. The product matrix output is written to sheets for filtering, sorting and diagnosing feed or Merchant Center issues. Google Sheets integration and workbook templates The script writes results directly into Google Sheets, typically into a pre-built workbook template. That workbook provides charts and pivot-ready tables that analysts can share, extend with formulas or schedule as a recurring report. Operational notes and intended use PMAx Insights is positioned as a diagnostic and investigative tool rather than an authoritative replacement for Google’s native reports. Community users report it can be brittle as PMax reporting and Google Ads script behaviors change, so outputs are most useful for direction and troubleshooting rather than absolute accounting.
