If your plumbing company runs Local Services Ads, the boxed listings with star ratings above the regular ads that charge per lead instead of per click, Google has news for you. Those ads are moving into Google Ads, and the campaign type they're moving into is called Performance Max.
That name is about to confuse a lot of plumbers. Performance Max is also the campaign type this guide tells you to hold back until Search has proven what a booked job costs. So is the migration a sign that Performance Max is now a launch-day campaign for plumbers? It isn't. The two share a name and very little else. This chapter separates them, then covers when the standard version earns a place in a plumbing account and how to build it when it does.
The Performance Max Your Local Services Ads Are Moving Into Isn't the One You'd Build
Google's help page calls the destination "Performance Max campaigns with pay-per-lead goals." Read the details and it's the Local Services product in a new home. The billing stays per lead, meaning a valid call, message or booking rather than a click. The placements stay where Local Services always sat, on Google Search and Google Maps, in the same spots on the page. What changes is the dashboard: budgets, settings and the lead inbox move into the regular Google Ads account.
The Performance Max a plumber would build from scratch is a different machine. Google describes it as one campaign that reaches all of its ad inventory: YouTube, Display, Search, Discover, Gmail and Maps. It bills by the click, like a Search campaign, and it decides on its own which of those channels gets each dollar.
The timing depends on the business. Google lists plumbing by name in its first wave, which began in August 2026 for "home and storefront service providers." Its second wave, set for late 2026, adds service-area businesses that have no storefront. Google doesn't spell out which wave a plumber running trucks out of a home office falls into, so watch for the notice: Google says it sends an email 14 days before an account moves, along with a banner in the Local Services dashboard.
Day to day, the move changes where the work happens more than what it is. Google says the Local Services lead inbox is replaced by a Leads page inside Google Ads, under Goals, then Conversions. Your past leads, contact details, message history and older call recordings move across automatically. You can upload up to 100 business photos to the new campaign and set callouts, up to six per category. The real change is one login: the pay-per-lead campaign sits in the same Google Ads account as your Search campaigns, so its leads and its spend show up right next to everything else, and comparing the cost of a Local Services lead with the cost of a Search lead stops requiring two dashboards and a spreadsheet.
Three details are worth acting on before your account moves:
- Download your Local Services reports now. Google says past performance reports won't carry over to Google Ads. Your lead history and call recordings do transfer; the reports don't.
- Check your targets by trade. A multi-trade company that set separate cost-per-lead targets for plumbing and HVAC inside one Local Services campaign loses that split. Google says it will calculate one campaign-level target for every category instead. If the trades need different targets, they need separate campaigns.
- Don't treat the move as permission to launch standard Performance Max. Your Local Services budget is moving. Your Search account's readiness for standard Performance Max hasn't changed at all.
Chapter 12 covers Local Services Ads as a product: how they rank, what they cost and how they fit alongside Search.
Standard Performance Max Waits for 30 Booked Jobs a Month From Search
Standard Performance Max is a learning machine. It decides which channel, which audience and which ad combination gets each dollar by watching what turns into conversions. Give it nothing to learn from and it spends your budget learning on your dime.
So it waits for the same gate as broad match in Chapter 6: 30 or more quality conversions a month coming out of Search. For most plumbing accounts that's somewhere around months six or seven. A busy shop with strong call volume can get there sooner; a one-truck operation may take longer. The month doesn't matter. The volume does.
When it launches, keep the setup plain:
- The same conversion goal as Search. The booked job if your field software sends it back, the qualified call if it doesn't yet. One goal, not a pile of them.
- No target cost per acquisition at launch. Let the campaign run on Maximize Conversions first and build its own history. Add a target later, once you can see what a job costs through Performance Max, not what it costs through Search.
- Its own budget. Isolation and Exploration keep running. Performance Max adds reach; it doesn't replace the campaigns that taught it what a job looks like.
Google itself pitches Performance Max as a complement to keyword-based Search campaigns, not a replacement. Search keeps priority where it matters. Google says that when a search exactly matches one of your exact match keywords, the Search campaign wins over Performance Max. "Water heater leaking," typed word for word, still goes to Isolation's hand-set bid.
8 of 12 Plumbing Sites We Checked Publish Coupons, Several With No Expiration Date. Final URL Expansion Can Land a Click on Them.
Performance Max ships with a setting called Final URL expansion switched on. In plain terms, Google gets to overrule your landing page: if another page on the same site looks like a better answer to the search, the click goes there instead. Google's own help page warns that this can sometimes point ads to unintended pages, and recommends URL exclusions to keep traffic off pages you don't want people landing on.
On a plumbing website, those pages are easy to name. In our example market, San Antonio, we read the sites of 12 plumbing and multi-trade companies:
- 8 of the 12 publish dollar coupons, and several of them carry no expiration date, an expiration with no year, or a rolling "expires in 90 days."
- 9 of the 12 have a careers page.
- 11 of the 12 run a blog or how-to articles.
A coupons page is the worst one to land on. Chapter 4 showed what happens when an ad promises one price and the page shows another. One example-market coupons page offers $50 off any service repair, with a $200 minimum purchase and the service call fee excluded. That's a fair offer on its own page. Land a homeowner there from an ad about a $79 drain cleaning and they're reading minimums and exclusions for a job they didn't ask about, before they've talked to anyone. A careers page sends a homeowner with a leak to a job application. A blog post about how to unclog a drain answers the question so well the homeowner doesn't call.
Before launch, either turn Final URL expansion off or add exclusions for every coupons, careers, blog and financing page on the site. Then, after the first two weeks, check which pages the clicks actually landed on, and add an exclusion for any page that shouldn't be there.
A Plumbing Asset Group Gets Built From What Search Already Proved
Performance Max doesn't use keywords. It uses asset groups: bundles of headlines, descriptions, images and video, plus signals that tell Google who you're looking for. A plumbing account that has run Search for six months already has most of what a good asset group needs. The trick is to bring it over instead of starting from scratch.
Search themes. Each asset group takes as many as 25 search themes, plain phrases naming the jobs you do. Take them from the Isolation job groups that book work: drain cleaning, water heater repair, slab leak repair, sewer line repair. Google says search themes compete with your phrase and broad match keywords, and lose to an exact match keyword that matches the search exactly, so they find new traffic without stealing Isolation's.
Headlines and descriptions. Bring over the Search headlines that earned the most clicks and booked jobs. They've already been tested on the same homeowners. Chapter 8's review-sourced lines belong here too.
Photos. Your own trucks, your own technicians, real jobs. A homeowner is deciding whether to let a stranger into the house, and a stock photo of a smiling model holding a wrench tells them nothing about who will show up.
Video. Performance Max can serve ads on YouTube, and Google says that if you don't provide a video, it will create videos automatically when possible from the assets you gave it. Film one instead: 30 seconds on a phone at a real job, a technician explaining what they found, is better than anything assembled from your logo and a stock clip. Google's minimum is 10 seconds per video, and it accepts horizontal, square and vertical versions.
Signals and exclusions.
- Brand exclusions keep Performance Max from buying searches for your own company name, which your brand campaign already covers cheaply.
- Location set to Presence, the same as Chapter 9.
- Custom segments describe your customer to Google with the search terms and competitor websites your customers use, built in the audience manager before you start.
- The URL exclusions from the section above.
Give each big service line its own asset group; one group for the whole company mixes the drain customer with the water heater customer. A drain cleaning asset group and a water heater asset group can each carry their own photos, headlines and themes, the same way Search keeps them in separate ad groups.
Building that asset group from a working Search account is how our Google Ads management team adds Performance Max to a plumbing account, after the conversion gate and not before.
Next: Demand Gen Reaches the Homeowner Before the Pipe Bursts
Search and Performance Max both wait for intent: someone with a problem, looking for help. Chapter 11 covers Demand Gen, the campaign type that reaches homeowners on YouTube, Discover and Gmail before they ever type "plumber."
