Performance Max pulls from one asset group across Search, Display, YouTube, and more — so it asks for the widest set of text assets of any campaign type.
A Performance Max asset group feeds every Google surface at once, so it needs short and long headlines, multiple descriptions, and a business name. The limits mirror Search and Display but the volume is higher — Google wants the maximum number of assets to assemble ads for each placement.
| Field | Limit | Notes |
|---|---|---|
| Headline (each) | 30 characters | Up to 15. Provide as many distinct ones as you can. |
| Long headline (each) | 90 characters | Up to 5. |
| Short description | 60 characters | One, for tight placements. |
| Description (each) | 90 characters | Up to 4. |
| Business name | 25 characters | Required. |
Headlines cap at 30 characters (up to 15), long headlines at 90 (up to 5), the short description at 60, standard descriptions at 90 (up to 4), and business name at 25. Provide the maximum assets so Google can build ads for every surface.
