SEO Runway Platform Verified: This guide utilizes live telemetry, algorithms, and automated workflows from the Google Ads Performance Intelligence (Navigation coordinate: /projects//google_ads/).

1. The PMax Black Box Problem

Performance Max automates bidding across Search, YouTube, Display, Discover, Gmail, and Maps. Without strict governance, the algorithm takes the path of least resistance: retargeting existing site visitors and bidding on branded queries rather than acquiring new customers.

Key takeaways
  • PMax campaigns frequently pad reported ROAS by bidding on your existing brand keywords and cheap, low-intent display placements.
  • Implement a Brand Exclusion List to force PMax to drive truly incremental, net-new customer acquisitions.
  • Audit asset group reporting to replace 'Low' performing creative assets with high-converting video and lifestyle imagery.
  • Use SEO Runway's unified search intelligence to verify whether PMax is stealing credit from your active organic search rankings.
If your PMax campaign is reporting a 900% ROAS, check your search terms; it is almost certainly bidding on your own brand name.
