What Is Performance Max?
Simple Explanation
Performance Max is a fully automated, AI-driven campaign type that runs ads across all Google platforms from a single campaign.
Instead of creating separate campaigns for Search, Display, and YouTube, you provide creative assets, a goal, and a budget. Google’s AI then decides where to show ads, who sees them, and how much to bid.
Simple idea:
Think of it as a smart assistant managing ads across multiple platforms at the same time.
Which Channels Does It Use?
Channels Overview
A single campaign can run across:
- Google Search

Most conversions come from Search and Shopping, while YouTube and Display help build awareness.

- Where to show your ad
