On This Page
Performance Max works for lead generation when your conversion tracking reports only qualified leads or sales, and when a Search campaign still covers your core service searches. Without those two things in place, Performance Max tends to find cheap form fills through Display and other placements, many of them spam. With them, it can add qualified leads from YouTube, Maps, Gmail and searches your keywords miss.
How Performance Max Finds Leads
Performance Max runs one campaign across Search, YouTube, Display, Discover, Gmail and Maps, choosing where to show ads based on your conversion goals, assets and audience signals. It optimizes toward whatever you count as a conversion, so the quality of that conversion matters more here than in any other campaign type.
Stopping Spam Leads
- Count qualified leads. Use enhanced conversions for leads and import qualified lead or sale status from your CRM, so bidding learns from real customers. Our guide to enhanced conversions for leads walks through the setup.
- Protect forms. Add bot protection and a required field a bot is unlikely to fill in sensibly, such as service needed.
- Remove weak conversions. Don't use page views, clicks or partial form starts as primary conversions.
- Watch placements. Check the channel report for spend drifting to Display while lead quality drops.
The Channel Performance Report
Google added a channel performance report to Performance Max that shows how Search, YouTube, Display, Discover, Gmail and Maps contributed to results. Check it monthly to see where the money went and compare that with lead quality in your CRM. Since October 2026 you can set search partners and the Display Network to Low priority in Performance Max and cap their share of the daily budget, as our channel prioritization guide explains. Google's own surfaces (Search, YouTube, Maps, Gmail and Discover) stay grouped as one unit, so your assets and settings still decide how spend splits among them.
Negative Keywords and Brand Exclusions
Performance Max now supports campaign-level negative keyword lists, which apply to its Search and Shopping inventory. Add the same negatives you use in Search, such as jobs, training and services you don't offer. Use brand exclusions to stop Performance Max taking credit for people who were already searching your business name, which makes its results look better than they are.
Asset Groups for Services
Build one asset group per main service, each with its own final URL, headlines, descriptions, images and video. A roofing company might separate roof replacement, repairs and gutters. Add search themes that describe each service the way your customers would.
Keeping Search Separate
Google generally gives a Search campaign with a matching exact keyword priority over Performance Max for the same search. Keep a Search campaign for your core services so you control the bids, ads and landing pages for your most valuable searches, and let Performance Max add reach elsewhere.
Signs It's Time to Pause
Pause Performance Max if its cost per qualified lead is still clearly worse than your Search campaigns after six to eight weeks with good tracking and exclusions in place.
