Local SEO for a plumbing company comes down to four things Google can see: a Business Profile that says exactly what you do and where you do it, a website with a page for each job you get hired for, reviews collected the way Google’s rules allow, and the license number your state puts on advertising. This guide covers each one, in the order worth doing them.
What Google actually ranks in local results
Google names three factors on its own help page, and the wording matters because two of them are outside your control on any given search.
Relevance is “how well a Business Profile matches what someone is searching for”. That is your category, the services listed on the profile, your description and the site behind it. It is the factor you can change this afternoon.
Distance is “how far each business is from the customer who’s searching”. A homeowner standing over a flooding laundry room is not searching from your yard. You cannot move your shop closer to them, which is why one business rarely wins its whole service area and why checking your position from your own office tells you almost nothing.
Prominence is “how well-known a business is”. Reviews and links to your site feed it, and it is slow. There is no shortcut, and Google states flatly that “there’s no way to request or pay for a better local ranking on Google”.
Notice what Google does not publish: no radius, no weighting between the three, no promise that the nearer truck wins. Any article giving you those numbers made them up. And if your profile does not appear at all, none of this applies yet, because that is a different problem with a different fix. Work through why a business isn’t showing up on Google Maps first and come back.
Set the profile up as a service-area business
Most plumbing companies travel to the customer, and Google treats that as a distinct kind of listing. If nobody visits your address, the instruction is to “remove your address and only enter your service area”, and a business with no permanent on-site signage customers can visit “should be listed as a service-area business”. A shop with a counter that sells parts keeps its address. A truck-and-warehouse operation does not.
Then the categories, which are the single highest-leverage field on the profile. Google’s instruction is to “select a primary category that best describes your business” and to “select a specific category from the list that shows up”. For a plumbing company, the primary is almost always Plumber. Additional categories exist “to inform your customers about special departments or services”, followed immediately by the sentence most agency guides skip: “Do not select a category for every product or service.”
So add a second or third only where you run a genuinely separate line of work, such as septic or water treatment. Type the job into the picker and take the exact match it offers. If there is no match, that service belongs on your website, not on the profile.
A category edit can cost you your visibility for a few days. Google’s own note: “If you add or edit an existing category, you might be asked to verify your business again.” Change categories deliberately, one round, not every week in search of a better result.
The service area itself has a hard ceiling. “You can have up to 20 service areas”, and “the boundaries of your overall area shouldn’t be more than about 2 hours of driving time from where your business is based.” Twenty entries will not name every town, subdivision and unincorporated pocket you drive to. Pick the twenty that bill the most, and let the website carry the rest.
Which plumbing pages to build, and in what order
Sort everything you are hired to do into three groups by the state the caller is in: emergencies, planned jobs, and required or recurring work. Build in that order. The full method, including when two services share a page, is in how many service pages your website needs, so here is only what it produces for plumbing.
| Job | Group | What that page has to carry |
|---|---|---|
| Burst pipe, no hot water, sewer backup | Emergency | Phone number above the fold, real answering hours, how fast you arrive, what to shut off before you get there |
| Drain cleaning | Emergency for a homeowner, recurring for a restaurant | Both cases in one page: the flooded-basement version and the grease-line schedule |
| Water heater installation | Planned | Tank versus tankless, what drives the quote, permit and venting work, photographs of your own installs |
| Sewer line repair | Planned | Camera inspection first, trenchless versus open cut, who owns the line to the main, restoration of the yard |
| Septic, well and pump | Planned, with recurring pumping | A different customer entirely: rural property, different equipment, often a smaller radius |
| Backflow testing, gas inspections | Required | The rule, the deadline, who is allowed to sign the report, what happens if it lapses |
Three things fall out of that table. Write an emergency page only if someone actually answers the phone at 2am, because ranking for it otherwise just sends business to whoever picks up next. Required-work pages look like the smallest opportunity and are usually the steadiest, since the same buildings come back on a cycle you can predict. And septic, well and pump work is close to a second business wearing your name, which is why it earns a real page rather than a bullet on a services list.
Your license number belongs on every page
This is the part general SEO advice leaves out, and it is not marketing advice. In several states your website is advertising, and advertising has a rule attached.
| State | The rule | What it covers |
|---|---|---|
| Texas | 22 TAC §367.10©: all advertising “designed to solicit plumbing business” must state the license number of the responsible master plumber, “regardless of the type of media used” | The Board’s penalty schedule lists $1,000 for failing to display or state it. Exemptions are narrow: national TV, franchisor ads, non-visual media such as radio, promotional caps and shirts, signs at your own premises, and third-party listings you do not edit |
| Florida | §489.119(5)(b): the registration or certification number “shall appear in each offer of services, business proposal, bid, contract, or advertisement, regardless of medium” | Also vehicles bearing your name or artwork, “conspicuously and legibly”. Business stationery and novelties such as balloons or pencils are excluded |
| California | Business and Professions Code §7030.5: a licensee “shall include his license number in … all forms of advertising, as prescribed by the registrar of contractors” | The statute defers the detail to the registrar, so check the current Contractors State License Board advertising regulation before you set type sizes |
The practical answer is the same in all three: put the number in the site footer, where it appears on every page you will ever publish, alongside the business name. Then it is handled once rather than page by page.
Some cities go further than their state. New York City requires four specific elements on a licensed plumber’s website, not just a number, which is worked through in service pages for NYC plumbers.
Read your own board’s current text before you sign off on a footer. Rules are amended, and this post is a starting point, not legal advice. If you work in more than one state, the strictest of them sets your footer.
Reviews: what Google’s rules actually allow
Reviews feed prominence, and prominence is the slowest factor to move, so the temptation to speed it up is where plumbing companies get into trouble.
“Offering incentives, like free or discounted goods or services, in exchange for customers to post reviews, change reviews, or remove negative reviews is considered fake & misleading content and is strictly prohibited.”— Google Business Profile Help, Ask customers for reviews
That covers the $25 off the next service call, the entry into a monthly draw and the discount for changing a one-star. The Maps content policy says the same thing from the other side and adds that merchants may “solicit or encourage the posting of content that does represent a genuine experience, without offering incentives to do so”.
Two more lines from the same policy that catch small companies out. Contributions “should reflect a genuine experience at a place or business”, so a review written by your dispatcher or your subcontractor is a conflict of interest, not a head start. And asking only the customers you expect to be happy is selective solicitation rather than review collection. The safe version is boring: ask everyone, the same way, every time.
What Google does sanction is direct. “To leave reviews, you can ask customers to visit a Google link or scan a QR code.” Put the QR code on the invoice the technician hands over, ask while you are still on site, and reply to what arrives, since “when you reply to customer reviews, it shows that you value their feedback”.
What to track, and how long it takes
Two free reports answer almost everything, and they answer different questions.
The Business Profile performance report covers the profile. Calls are “the number of times a customer clicked on the call button on your Business Profile”. Website clicks, direction requests, views and messages sit beside them, and the searches report shows “the search terms people used to find your business”, updated at the start of each month and taking up to five days to appear. Only verified profiles show any of it.
Search Console covers the site. Impressions are “how many times your site appeared in Search results”, average position is “the average position of the topmost result from your site”, and the queries view “groups your data by the search query users typed”. That is how you find out whether your water heater page is being shown for water heater searches or for something you never meant to sell.
| What you watch | Where | What a good month looks like |
|---|---|---|
| Calls from the profile | Business Profile performance | Rising in the months your trade is busy, steady otherwise |
| Search terms reaching the profile | Business Profile performance | Job words appearing, not just your company name |
| Impressions per service page | Search Console | Every published page collecting some |
| Average position for your job words | Search Console | Moving toward the first page over quarters, not weeks |
Now the honest part. Google publishes no timeline for local results. What it does say about its index is that “some changes might take effect in a few hours, others could take several months”, and that you “likely want to wait a few weeks to assess whether your work had beneficial effects in Google Search results”. Profile fields move fastest. New pages need to be found, indexed and then judged. Reviews and links accumulate at the speed of the work you actually do. Anyone selling you a guaranteed month is selling something Google says it does not sell.
Twenty service areas will not cover a metro, so the website carries the rest. LocalBiz builds the site, generates the service and location pages and the blog posts behind them, helps with the Google Business Profile work, and tracks where you rank across the whole service area instead of from your own address. What you want more calls for stays your decision. Pricing is on the home page.
A 90-day plan you can run between jobs
Roughly two hours a week, in this order, because each step makes the next one worth more.
| Days | Do this | Why it comes here |
|---|---|---|
| 1–15 | Claim and verify the profile. Set primary category, hours, phone. Remove the address if nobody visits you. Enter your twenty best service areas | Nothing else counts until the profile is verified and visible |
| 16–30 | Add the license number to the site footer. Check it against your state board’s current rule | One change, every page, and the compliance question is closed |
| 31–50 | Write the two emergency pages you can genuinely staff, then your top planned job | Fastest-converting demand first, and it tells you whether the phone setup works |
| 51–70 | Write the required-work pages: backflow, gas inspections, septic pumping if you do it | Slow, steady, and almost nobody local has written them properly |
| 71–85 | Start asking every customer for a review, the same way each time. Reply to all of them | Prominence takes months, so it should have started already |
| 86–90 | Open both reports, record where you are, and set a monthly date to look again | A baseline you wrote down beats a memory of how last spring felt |
Three months in, you will have a verified profile that names the right work, a footer that satisfies your state, four or five pages that answer real jobs, reviews arriving on their own, and two numbers to watch. The trade is not shrinking: the Bureau of Labor Statistics counted 510,600 plumbing, pipefitting and steamfitting jobs in 2025 and projects seven percent growth to 2035. The companies that get found are the ones whose pages answer the search that was typed. More on how we think about local search is on the LocalBiz blog.
Frequently asked questions
How long does local SEO take for a plumbing company?
Google publishes no figure, and anyone quoting three to six months is quoting their own experience. What Google does say about its own index is that “some changes might take effect in a few hours, others could take several months”, and that you “likely want to wait a few weeks to assess whether your work had beneficial effects”. Profile edits move fastest. New pages and reviews are slower.
Do I have to put my license number on my website?
In several states, yes, and the website counts as advertising. Texas requires the responsible master plumber’s license number in all advertising “regardless of the type of media used”, with a $1,000 penalty in the Board’s schedule. Florida requires it in each advertisement “regardless of medium”. California requires it in all forms of advertising. Check your own state board before you publish.
Can I offer a discount to customers who leave a review?
No. Google’s wording is that offering incentives “like free or discounted goods or services, in exchange for customers to post reviews, change reviews, or remove negative reviews is considered fake & misleading content and is strictly prohibited”. You may ask every customer, in person or with a link or QR code, as long as nothing is offered in return.
Should a plumbing company hide its address on Google?
If customers never come to you, Google’s instruction is to remove the address and enter only a service area, and a business without permanent signage customers can visit “should be listed as a service-area business”. A shop that does take walk-in counter sales keeps its address. Do not list a home you would rather not publish while also claiming visitors are welcome.
