Quick answer: Search vs Performance Max: start most service businesses on Search, then add Performance Max once tracking and conversion volume are solid.
Google pushes Performance Max (PMax) hard, and it has improved a lot. But “improved” doesn’t mean “right for every business”. Here’s how the two compare in 2026.
What each campaign does
Search campaigns show text ads on Google search results when people type searches matching your keywords. You choose keywords, write the ads and control bids and budgets.
Performance Max is a goal-based campaign that runs across all of Google’s channels from one campaign: Search, Shopping, YouTube, Display, Discover, Gmail and Maps. You provide assets (text, images, videos), audience signals and a goal, and Google decides where and to whom to show ads.
What’s changed recently
PMax used to be a “black box”. Over 2025 and 2026 Google added much more control and reporting, including:
- Channel performance reporting: see results by channel, such as Search, YouTube and Display.
- Search terms reporting: see the searches that triggered your ads.
- Campaign-level negative keywords: block irrelevant searches inside PMax (these apply to Search and Shopping inventory, not YouTube or Display placements).
- Brand exclusions and better asset reporting.
When Search is the better choice
- You’re a service business that wants calls and enquiries.
- Your budget is modest. PMax spreads spend across many channels, and needs conversion data to perform well.
- You want tight control over which searches you show for and how much you pay.
- Your conversion tracking is new or unreliable.
When Performance Max makes sense
- Ecommerce with a product feed in Google Merchant Center. PMax is the main way to run Shopping ads now.
- You have solid conversion tracking with plenty of conversions each month.
- You have good images and video, or are willing to create them.
- You want to reach people across YouTube and Display as well as Search.
Can you run both?
Yes. Many accounts run Search for their main keywords and PMax alongside. When a search query exactly matches a keyword in your Search campaign, the Search campaign generally takes priority. Use PMax brand exclusions and negatives so it doesn’t simply take credit for searches for your own business name.
My recommendation for most small service businesses
- Start with a well-built Search campaign and working conversion tracking.
- Once you’re getting steady conversions, test PMax with a separate budget.
- Check channel reporting and search terms regularly, and compare cost per enquiry, not just volume.
