Performance Max is Google’s most advanced campaign type, yet 67% of marketers still don’t fully understand how to use it effectively. Launched in 2021 and evolving quickly, it automates ad delivery across Google Search, Shopping, Display, YouTube, Gmail, Discover, and Maps using AI to maximize conversions.
But Performance Max isn’t just another campaign type, it changes how marketers approach control, targeting, and optimization.
What Is Performance Max?
Performance Max (PMax) is an AI-powered Google Ads campaign that shows ads across all Google properties using machine learning to find your best customers and optimize for conversions.
Think of it as handing Google your goals, creative assets, and budget—and letting its AI handle placements, bids, and targeting in real time.
How Performance Max Works
What Google’s AI Actually Does
- Analyzes user intent signals in real time
- Builds ad combinations from provided assets
- Optimizes bidding automatically
- Distributes ads across all Google platforms
- Learns from performance to improve outcomes
Where Your Ads Appear
