Performance Max vs Search Campaigns: When to Use Each
Both campaign types can drive conversions. They do it differently, and mixing them incorrectly costs you. Here's the framework for deciding which to use — and how to run them together.
- Search gives you control and transparency — essential for brand terms and exact-intent queries
- PMax gives you scale and multi-channel reach — best for proven products with strong conversion data
- Most accounts should run both: Search for high-intent keywords, PMax for everything else
- PMax without brand exclusions will cannibalise your Search campaign's credit
The core difference
Search campaigns give you control: you choose which keywords trigger your ads, write specific ads for each theme, and send traffic to specific landing pages. You can see exactly what queries matched and exclude the ones that don't convert. That precision has a cost — you only reach people who are actively searching for your keywords.
Performance Max gives you reach: one campaign can serve across Search, Shopping, Display, YouTube, Gmail, and Maps. Google's AI decides where to show your ads based on your conversion goals and asset groups. You give up control for scale. The question is whether that trade-off is worth it for your business.
| Factor | Search | Performance Max |
|---|---|---|
| Targeting control | High — keyword-level | Low — AI-driven |
| Transparency | Full search terms report | Theme clusters only |
| Channels | Search only | All Google channels |
| Creative formats | Text ads | Text + image + video |
| Best for | Brand, competitor, high-intent | Prospecting, ecommerce, scale |
| Min. conversion data needed | Low — works with limited data | High — needs 30+/month to optimise |
| Setup complexity | Medium | High (asset creation) |
Running PMax and Search without brand exclusions on PMax is the single most common mistake we see in new Google Ads accounts. PMax will claim credit for conversions that would have happened anyway through brand Search — making its ROAS look exceptional while hiding its actual prospecting performance.
When Search wins
- Brand campaigns: Protect your brand terms from competitors. Search with exact match gives you maximum control.
- High-intent competitor campaigns: Targeting competitor brand terms requires precise ad copy and landing page alignment — better managed in Search.
- Low conversion volume accounts: PMax needs data to work. New accounts or low-spend accounts perform better with focused Search campaigns.
- Regulated industries: Legal, medical, financial services — where query-level control and compliance review matters.
- Service businesses with specific geography: Local services need precise location + keyword targeting that Search handles better.
When PMax wins
- Ecommerce with a broad product catalogue: PMax + Shopping feed is the strongest ecommerce combination Google offers.
- Proven products with strong conversion data: Once you know a product converts, PMax can scale it across all Google inventory.
- Prospecting beyond search intent: PMax can reach users on YouTube and Display before they search — valuable for considered purchases.
- Accounts spending $10K+/month: At sufficient scale, PMax's multi-channel reach is a genuine advantage.

The recommended structure for most accounts is:
- Branded Search campaign (exact match) — protect your brand terms, capture high-intent branded queries at efficient CPAs
- Non-brand Search campaigns (phrase/broad with negatives) — high-intent non-brand queries you want to control precisely
- Performance Max campaign with brand exclusion list — prospecting and scale across all channels, excluding brand terms
Launch Search first, accumulate conversion data, then add PMax once you have 30+ conversions per month. When you add PMax, apply brand exclusions immediately and monitor the Search campaign's impression share — if it drops significantly, PMax is competing with it on brand terms.
