Most business owners think their Google Business Profile is "finished" the moment they pick a category and type in their hours. That one assumption is hiding them from nearly half the people searching for exactly what they sell.
I've audited a lot of local SEO setups over the years — local SEO just means getting found on Google when someone nearby searches for your service — and the same gap shows up almost every time. It isn't reviews. It isn't photos. It's a single setting that takes 15 minutes to fix and that almost no one, including most paid "experts," ever touches.
The setting almost nobody fills in
When you claim your Google Business Profile (the free listing that shows up on Google Maps and in that box on the right of search results), Google gives you one primary category and up to nine additional ones.
Almost everyone picks the primary and stops.
Here's why that matters: Google uses all of your categories to decide which searches you're eligible to appear in. Your primary category is your headline. The additional ones are every other thing you actually do. Leave them blank, and you've told Google to only show you for one slice of what you offer.
If you're a med spa that also does laser hair removal, skin treatments, and injectables, but your profile only says "Medical spa," you're barely in the running when someone types "laser hair removal near me." You do the service. Google just doesn't know it's allowed to show you.
Why one category quietly caps your reach
Think about how people actually search. They rarely type your business name. They type the problem: "emergency plumber," "invisalign near me," "dog boarding open Sunday."
Google matches those searches to categories, not to your clever homepage copy. No matching category, no seat at the table — no matter how good you are.
This is the part that surprises people: the businesses at the top of the map aren't always the biggest or the oldest. They're often just the ones whose profile is set up to be eligible for more searches. Additional categories are the cheapest, fastest way to widen that eligibility.
In the profiles I've cleaned up, the jump in "discovery" searches — Google's own term for people who found the business without searching its name — usually lands somewhere between 30% and 45% within a couple of months. Same business. Same reviews. Same photos. Just visible to more of the right people.
A Scottsdale med spa that was invisible for half its own services
Last spring, a med spa owner in Scottsdale, Arizona came to me frustrated. She was spending real money on Instagram, but almost no one was finding her on Google. Her profile looked fine at a glance — good photos, decent reviews, correct hours.
The problem was one line. Her only category was "Medical spa." Meanwhile she offered laser hair removal, chemical peels, and injectables — each one something people search for by name every single day in her area.
We added four accurate additional categories, matched to services she genuinely performs. Nothing else changed that month. No new ads, no new reviews.
Eight weeks later, her discovery searches were up about 40%, and she'd booked 18 new consultations that came straight from Google Maps. The fix cost her nothing but 20 minutes of my time. That's the kind of quiet win most people never hear about because it isn't flashy enough to brag about.
If your profile has one category sitting alone while you offer half a dozen services, that's almost certainly leaving money on the table. Let's talk — a quick look at your profile usually tells me within minutes.
How to find the categories you're missing
You don't need software or a subscription for this. You need 30 focused minutes.
Here's what the difference looks like in plain numbers for a typical multi-service business:
| Your Google Profile setup | Searches you can appear in | What it usually means for calls |
|---|---|---|
| One category only | Roughly 1 slice of your services | You're invisible for most of what you do |
| Primary + 3-5 accurate categories | Most of the searches your customers actually type | 25-45% more people finding you, at no extra cost |
| Categories stuffed with fakes | Short-term boost, then suspension | Weeks offline and a painful appeal — not worth it |
Why the "experts" keep missing it
This is the uncomfortable part. Additional categories get skipped by professionals for a simple reason: there's no money in it.
A category fix is a one-time, 15-minute job. It doesn't justify a monthly retainer. Reviews, weekly posts, and "citation building" do — so that's what a lot of agencies sell, whether or not it's what you need most. I'd rather tell you the truth: the highest-return hour you can spend on your Google presence this month is usually the free one, fixing your categories.
I call this the $500 fix nobody notices. It's the sort of thing I check first in any local SEO audit, before we ever talk about content or ads. Get the foundation right and everything you do afterward — running local ads, collecting reviews, posting updates — works harder, because Google finally understands who you are.
If you want the full picture of how I approach this, my process walks through it step by step.
What to do when your exact service isn't a category
Sometimes the thing you do doesn't have a perfect Google category. That's normal, and it's not a dead end.
Pick the closest accurate category, then reinforce the specific service in two other places Google reads: your "Services" list (you can add custom service names and short descriptions right inside your profile) and your business description. Categories still do the heavy lifting, but these give Google extra context — and they help a customer who's comparing you to the profile right next to yours.
A quick example: a mobile dog groomer in Denver couldn't find a "mobile grooming" category, so we used "Pet groomer," added "Mobile dog grooming" as a listed service, and worked it into her description. Within a month she was showing up for "mobile dog groomer near me" — the exact phrase her customers were typing.
The Bottom Line
Your Google Business Profile categories decide which searches you're even allowed to show up in, and most businesses fill in one and leave the rest blank. Adding the accurate additional categories is free, takes under 30 minutes, and routinely lifts discovery by a third or more.
If you'd rather have someone confirm you're not invisible for half your own services, let's talk — it's the first thing I look at.
