Performance Max vs. Demand Gen
Choose Performance Max when you have existing demand to capture and conversions to maximize across every Google channel at once. Choose Demand Gen when you want to create demand — on YouTube, Discover and Gmail, with real creative control and audience targeting rather than search intent. They aren't exclusive: PMax harvests, Demand Gen sows.
PMax optimizes for conversion against existing demand; Demand Gen builds new demand in visual surfaces, with creative control.
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 have a catalogue or a clear conversion flow, you want coverage across every Google channel, and you accept handing placement control to the algorithm.
Demand Gen
The campaign type that replaced Discovery, optimized for visual discovery and top-of-funnel demand (YouTube, Shorts, Discover, Gmail, Display). Integrates the product feed and omni-channel (online + offline) bidding.
The brand is little known, search demand is thin, and visual creative is a strength — you want to be discovered, not just found.
