What each campaign type is
Search campaigns
The classic Google Ads campaign. You pick keywords like “roof replacement Calgary”, write text ads and choose the landing page. Your ads show on Google Search when people search for those terms. You see exactly which searches triggered your ads, and you can block the ones you do not want.
Performance Max
A goal-based campaign that uses Google’s automation to show ads across all of its inventory from one campaign. You provide assets (headlines, descriptions, images, logos, video), a landing page, conversion goals and optional audience signals. Google decides which combination to show, where and to whom.

Side-by-side comparison
| Search | Performance Max | |
|---|---|---|
| Channels | Google Search (plus optional search partners) | Search, YouTube, Display, Discover, Gmail, Maps |
| Targeting | Keywords you choose | Automated, guided by assets, audience signals and search themes |
| Ad creative | You write and control each ad | Google assembles ads from your asset library |
| Control | High: keywords, negatives, bids, ad schedule, landing pages | Lower: brand exclusions, negative keywords, URL rules, asset choices |
| Reporting | Full keyword and search-term reports | Search-term insights, channel and asset reporting, less detail |
| Data needed | Works from day one | Works best with steady, accurate conversions |
| Main risk | Manual work and missed opportunities | Spending on low-quality leads or brand searches you would win anyway |
How the two interact in one account
If you run both, they can compete for the same search. Google has explained how it decides:
- If a search exactly matches an exact-match keyword in a Search campaign (or the query is identical to the keyword), the Search campaign is generally prioritized.
- Otherwise, the ad with the higher Ad Rank and relevance serves, which may be PMax.
So your most valuable searches, where you want to control the message and landing page, should live in Search as exact and phrase match keywords. PMax then finds additional demand around them.

When Search is the right choice
- Local lead generation. Plumbers, lawyers, clinics and contractors usually get their best leads from people actively searching for a service.
- New accounts. Without conversion history, PMax has little to learn from.
- Tight budgets. Search spends only on the searches you choose.
- Specific services. When you want certain jobs and not others, keywords give you that control.
- Regulated or sensitive industries. Legal, health and financial advertisers often need tight control over messaging and placement.
When Performance Max makes sense
- You have accurate conversion tracking, ideally with offline imports of qualified leads or sales. See the conversion tracking checklist.
- Steady conversion volume, so the campaign has enough signals to learn.
- Good creative: real photos, a short video, strong headlines. Weak assets produce weak ads everywhere.
- E-commerce and product feeds. PMax is Google’s main campaign for Shopping inventory.
- You want reach beyond Search, for example YouTube and Maps, and you have measured Search’s ceiling.
A practical rollout plan
Before you launch Performance Max:
- Primary conversions are real leads or sales only
- Offline conversions (qualified lead or closed sale) are imported where possible
- Brand exclusions are added so PMax does not take credit for brand searches
- Account-level negative keywords cover jobs, DIY, free and irrelevant terms
- Final URL expansion is off, or limited with URL rules, if you only want certain pages
- Assets include real photos, a logo, a short video and 10+ headlines
- Audience signals include your customer list and website visitors
- Location targeting is set to “Presence” for local businesses
How to judge Performance Max fairly
PMax reports can look better than reality because they may include conversions from brand searches and remarketing to people who were already going to buy. To judge it fairly:
- Compare cost per qualified lead or cost per booked job, using CRM data, not just platform conversions.
- Check channel reporting to see how much ran on Search, YouTube, Display and Discover.
- Review search-term insights for brand terms and irrelevant themes.
- Watch total leads across the account. If PMax rises while Search falls by the same amount, it may just be taking credit.
- Run it for at least 4–6 weeks before deciding, and avoid big changes during the learning period.
Which should your business use?
Frequently asked questions
Is Performance Max better than Search?
Not automatically. PMax offers reach and automation across Google, while Search offers control and transparency. For most local lead-generation businesses, Search should be the foundation.
Can I add negative keywords to Performance Max?
Yes. Google now supports negative keywords for Performance Max, alongside account-level negatives and brand exclusions. Check current limits in your account.
Will Performance Max steal traffic from my Search campaigns?
It can compete for the same searches. Exact-match keywords in Search are generally prioritized when the query matches exactly; otherwise the stronger Ad Rank wins.
How much data does Performance Max need?
There is no fixed number, but it performs best with steady, accurate conversions. Accounts with only a handful of conversions a month usually do better with Search first.
Should I use Performance Max for lead generation?
It can work if you import qualified leads or sales from your CRM so it optimizes for real customers, not just form fills.
