Google has already told you how Maps rankings work. It's in their own documentation: relevance, distance, and prominence. Three factors.
The entire "GMB optimization" industry exists to make those three words sound complicated enough to charge you $500 a month for.
I've spent ten years managing marketing for service businesses — 63+ clients since 2021 — and here's the honest version: one of those factors you can't touch, and the other two come down to a short list of unglamorous work you can mostly do yourself. Let me translate Google's three words into plumber.
Distance: the one you can't change
When someone searches "plumber near me," Google weighs how close each business is to that searcher. You cannot optimize your way around a competitor who's two miles closer to the customer.
This is worth internalizing, because it kills two illusions:
- There is no single "ranking" on Google Maps. You rank differently from every street corner in town. The guy who checks his ranking from his own office is checking the one spot on earth where he ranks best.
- Anyone who promises "#1 on Google Maps" is lying, because #1 depends on where the searcher is standing. Rankings can generally be improved — in many markets, dramatically — but nobody can promise a position. Including me.
So the game isn't "rank #1." The game is: show up in the top three across the widest possible radius. And that's a relevance and prominence game.
Relevance: does Google understand what you do?
Relevance means how well your profile matches what was searched. This is the cheapest ground to gain, because it's pure completeness.
Get the categories exactly right
Your primary category is the loudest thing you say to Google. If you're a plumber whose money jobs are water heaters, "Water heater repair service" as a secondary category — or even primary, depending on your business — changes which searches you're eligible for. Add every secondary category you legitimately fit.
List every service, with real descriptions
Google lets you list individual services under each category and describe them. Most owners leave this blank. Fill in every service you perform with a couple of honest sentences each. When the search is "sewer line replacement," a profile that literally lists and describes sewer line replacement is the relevant one.
Completeness across the whole profile — hours, service areas, attributes, the works — is the rest of the relevance picture. I've written the full field-by-field walkthrough in my GBP optimization guide, including the 30-day sprint: complete profile, 20 photos, 10 posts, in 30 days.
Prominence: does Google believe you matter?
Prominence is Google's read on how established and trusted your business is. And in local services, the biggest prominence lever you control is reviews.
Reviews: count, velocity, recency
Three dimensions matter:
- Count. Roughly 10 reviews is enough to start testing Local Services Ads. Around 50, you're competitive in many markets. Past 100, you're the authority option in most searches.
- Velocity. A steady stream beats a pile. Fifteen reviews a month, every month, signals a business that's alive and busy.
- Recency. Forty reviews that all date from 2023 tell Google — and every customer reading them — that something changed.
The mechanism is boring and it works: ask every customer at job completion, text them a direct review link, and reply to every review you get. And if you're wondering what number to aim for in your market, I broke down the full ladder in how many Google reviews do I need.
I won't promise reviews buy you rankings — nobody honest will. But Google names reviews as part of prominence in its own docs, and in many markets the map pack visibly tracks review strength. It's the strongest correlation you'll find between work you control and results you want.
Photos and activity
A profile with 40 real job photos, new ones added monthly, and a weekly post looks like a living business. A logo and two photos from 2022 looks like a maybe. Upload real photos — trucks, crew, before-and-afters — and keep a simple posting cadence.
Your presence beyond the profile
Prominence also draws on your wider footprint: your website, mentions of your business around the web, consistency of your name-address-phone on the sites that matter. Useful, real, and secondary. Get the profile and reviews humming first.
What's noise: three things to stop paying for
Because relevance and prominence sound abstract, an entire cottage industry sells rituals in their name. Three to walk away from:
- Daily "check-ins" and geo-tagged photo schemes. The theory is that daily activity from job sites moves rankings. There's no evidence Google rewards this ritual, and the hours add up. One real photo set a week beats a daily ceremony.
- Citation subscriptions. Paying monthly rent to stay listed in 300 directories nobody visits. Consistent listings on the handful of major sites is a one-time cleanup, not a subscription.
- Cheap "GMB optimization" gigs. The $50 Fiverr special and the $99/month mystery service. At best they fill in fields you could fill in yourself in an afternoon. At worst they keyword-stuff your business name and earn you a suspension — and I've seen the aftermath enough times to have written a whole suspension recovery guide.
The pattern: if the deliverable is activity instead of outcomes — reports, submissions, check-ins — it's noise.
What this looks like in practice
A plumber I'll call Marco is a good composite of how this usually plays out. Solid operator, 14 reviews, most of them two years old, primary category set to a generic label, zero services listed, six photos. Paying a "GMB service" $250 a month for reports nobody read.
The fix wasn't clever. Cancel the service. Fix categories in an afternoon. List 22 services with descriptions. Shoot 30 photos across a week of jobs. Start texting a review link at every job completion — and reply to every review within a day, because replies are engagement and the next customer reads them.
No tricks, no daily check-ins, no directory blast. Just the two levers Google actually names, pulled consistently. That's the boring truth about the map pack: in many markets, the top three aren't the best businesses. They're the most complete, most reviewed, most alive-looking ones.
What I'd do
If I owned a plumbing company that wasn't cracking the map pack, here's my order of operations:
- This week: fix primary and secondary categories, list every service with descriptions, complete every profile field.
- This month: upload 20+ real photos and launch the review machine — ask at every job completion, text the link, reply to everything.
- Every month after: keep review velocity up, add photos, post weekly. Judge progress by calls and direction of travel across the service area, not by your rank from your own driveway.
Give it 90 days of consistency before you judge it. Rankings generally follow the businesses that look most alive and most trusted — because that's literally what Google says it's measuring.
