Performance Max vs. AI Max
AI Max doesn't replace Performance Max — they're different things. AI Max brings AI logic (keywordless matching, URL expansion, text customization) into the Search campaigns you control. Performance Max is an umbrella campaign that runs itself across every channel. Pick AI Max if you want AI with visibility on Search; PMax if you want maximum reach with minimum control.
AI Max is an AI layer over Search, with search-term reporting; PMax is a separate, multi-channel campaign with limited placement visibility.
AI Max
AI Max for SearchA layer of AI features you switch on over classic Search campaigns (not a new campaign type). It extends matching beyond your set keywords, dynamically generates headlines and descriptions, and picks the optimal landing page. Out of beta in 2026; campaigns with DSA, campaign-level broad match and automatically created assets auto-upgrade to AI Max.
You already have Search campaigns that perform and want reach growth without losing search-term reporting.
PMax
Performance Max (PMax)The umbrella campaign that runs one AI logic across all Google channels at once: Search, Display, YouTube, Discover, Gmail, Maps. You supply assets, audience signals and conversion goals; the algorithm handles bidding, placement and creative assembly. Replaced Smart Shopping in 2022.
You want one campaign covering Search, YouTube, Display, Discover, Gmail and Maps, and conversion volume justifies the learning period.
