How Home Service Businesses Can Use Performance Max Without Losing Control of Their Budget
PMAX is Google's most powerful campaign type and also the easiest to misuse. Without the right asset groups, audience signals, and brand exclusions, it will burn your budget on low-quality traffic. Here is how to run it correctly.
Performance Max is Google's all-in-one campaign type that runs across Search, Display, YouTube, Gmail, Maps, and Discover simultaneously. For home service businesses, the appeal is obvious. One campaign covering every placement sounds efficient.
The problem is that PMAX with weak inputs produces weak results across every placement at once, and diagnosing what is wrong is harder than with standard campaign types.
The most important input is your asset group. PMAX uses your headlines, descriptions, images, and videos to build ads across every format. Most home service businesses set this up with two headlines and a logo. That is not an asset group.
You need at least eight to ten headlines that speak to different angles of your service, descriptions that address objections, real photos of your team and finished work, and ideally at least one video even if it is a simple thirty-second walkthrough filmed on a phone.
Audience signals are the second critical input. PMAX uses signals to find people who resemble your best customers. If you give it no signals, it starts from scratch and burns budget while learning.
Feed it your existing customer list, your website visitors, and any similar audiences you have built in Google Ads.
A roofer who gives PMAX a list of two hundred past customers as an audience signal will see dramatically better results in the first thirty days than one who gives it nothing.
Brand exclusions matter more in PMAX than in any other campaign type. Without them, PMAX will spend a significant portion of your budget capturing branded search queries, meaning people who were already searching for your company by name.
Those clicks would have happened anyway. Add your business name and any common misspellings as brand exclusions so PMAX spends its budget finding new customers instead of claiming credit for existing ones.
