Performance Max (PMax) is Google’s all-in-one automated campaign type that serves ads across Search, YouTube, Display, Discover, Gmail, and Google Maps from a single campaign. Driven by Google AI, PMax maximizes conversions by finding high-intent buyers wherever they browse.

4 Core Components of a High-Converting PMax Campaign
| Component | Best Practice | Why It Matters |
|---|---|---|
| Asset Groups | Organize by product category or theme (min 5 headlines, 5 descriptions, 15 images, 5 videos) | Prevents generic ad copies from serving to wrong audiences |
| Audience Signals | Add custom intent keywords, customer match email lists & competitor searchers | Steers Google AI toward your exact ideal buyer profile fast |
| URL Expansion Settings | Turn OFF final URL expansion if you want strict landing page control | Prevents Google from sending traffic to irrevelant blog pages |
| Negative Keywords | Apply account-level negative lists (see our negative keyword guide) | Blocks search queries bidding against your branded terms |
