Performance Max (PMax)
Performance Max is Google's AI-driven, cross-channel campaign type that runs ads across Search, Display, YouTube, Gmail, Discover, and Maps from a single campaign. It uses machine learning to optimize for conversions, requiring only assets and goals from advertisers.
Example in Practice
"Migrating from Smart Shopping to Performance Max increased our ROAS from 4.2x to 5.8x while expanding reach to YouTube and Discover placements."

Asset Groups
Asset Groups are collections of creatives (images, videos, headlines, descriptions) within Performance Max campaigns. Each Asset Group targets a specific audience signal and product set. Think of them as ad groups, but for PMax's cross-channel format.
Audience Signals
Audience Signals in Performance Max tell Google who your ideal customers are. They include your data (customer lists, website visitors), custom segments, demographics, and interests. They're suggestions to the algorithm, not hard targeting - PMax can expand beyond them.
