Google Performance Max vs search ads: which should you use?
Kahu team·Updated 1 Oct 2026·7 min read
Search campaigns show text ads to people searching specific keywords, with clear control over where money goes. Performance Max uses Google’s automation to show ads across Search, YouTube, Display, Maps and Gmail from one budget. For most small service businesses, Search is the better start. Performance Max can help once tracking is accurate and you have enough conversion data.
How each campaign type works
| Search | Performance Max | |
|---|---|---|
| Where ads appear | Google search results | Search, YouTube, Display, Maps, Gmail, Discover |
| You choose | Keywords, ads, bids | Goals, assets, audience signals |
| Control | High | Lower, with growing reporting |
| Needs | Good keyword lists | Accurate conversion tracking and creative assets |
| Best for | Clear demand, limited budget | Several products, more data |

- Search is already profitable and you want to grow.
Running both
