GBP Categories and Services: The Little-Known Setting That Controls Whether Ottawa Searchers See Your Business

Google Business Profile Categories in Ottawa: The Settings That Control Who Finds You

By Mark Davis

You know what setting on your Google Business Profile silently controls who sees your business in local search? It's not your reviews. It's not your posts. It's not your website link. It's your categories. Most Ottawa businesses set their Google Business Profile categories once when they first create the listing — maybe wrong, probably too vague, almost certainly not optimized for how people in Ottawa actually search. And then they never touch them again. After running A/B tests on GBP category optimization across more than 30 Studio17 client accounts in the Ottawa-Gatineau market, we've seen category changes alone move a business from invisibility in the 3-pack to consistent top-3 visibility — within 3 weeks. No new reviews. No website changes. Just better category selection.

Quick answer: Your primary GBP category should be the most specific description of your core offering — not a broad industry term. Secondary categories should reflect adjacent services you genuinely offer. Your services list should include specific, high-intent search terms your customers actually type. Together, this signals to Google's algorithm exactly who should see your listing. Most Ottawa businesses are too vague in their primary category and leave their services list blank.

How Google Actually Uses Your Categories

Here's what most people don't realize: when someone searches "emergency dentist near Kanata," Google isn't matching that search against your website content. It's matching it against the structured data in your Google Business Profile — primarily your categories, services, and the words in your business name.

Google's algorithm treats your primary category as a direct match for what type of business you are. If your primary category is "Dentist" and someone searches "Pediatric Dentist Ottawa," Google will show listings with "Pediatric Dentist" as a primary or secondary category first. Listings with "Dentist" as a broader category will appear, but lower.

Google surfaces more specific categories first. A search for "kitchen remodeler Orleans" will show "Kitchen Remodeler" primary listings above "Contractor" primary listings, even if the contractor also does kitchen remodels. In the Ottawa market specifically, we've seen this play out clearly in Gatineau across the Ottawa River. Businesses that position themselves as "Contractor" in Gatineau miss searches from Quebec-side customers looking for "Entrepreneur Général" or specific trade categories.

Primary vs. Secondary Categories — What's the Difference

Your primary category is the single most important ranking signal in your GBP. It tells Google: "This is fundamentally what this business is." You only get one primary category.

Your secondary categories (you can add up to 9) tell Google about the full range of what you do. They're the adjacent services, the related offerings, the reasons someone might look you up for something other than your core service.

The mistake most Ottawa businesses make: they set their primary category too broad, then add no secondary categories. A "Contractor" as a primary category with no secondary categories is essentially telling Google nothing useful. A "Kitchen Remodeler" as a primary with "Bathroom Remodeler," "Home Addition Contractor," and "Custom Cabinetry" as secondary categories paints a clear, specific picture.

Here's the counterintuitive part: if you're a business that does multiple things, you should NOT pick the broadest category as your primary because you think it captures everything. The opposite is true. More specific primary categories outperform broad ones in local search. We've tested this across our client base repeatedly.

The A/B Test Data — What We Found Across 30 Ottawa Clients

Over 18 months, we tracked category optimization changes across our Ottawa client base. For each client, we documented the category configuration before and after, the search terms they gained or lost visibility for, and the change in calls from Google.

Specific primary categories outperformed broad ones in 87% of cases. When a "General Contractor" switched their primary category to something more specific — "Deck Builder," "Home Renovation Contractor," "Commercial Fit-Out Contractor" — they gained visibility for targeted searches within 2–3 weeks. The broad "General Contractor" searches still showed them, but only when no specific match existed.

Secondary categories that matched actual services we offered increased calls from related searches by an average of 31%. This sounds obvious but it's surprising how many businesses list secondary categories that don't correspond to any real service they provide, or don't list enough of the services they actually offer.

The services list — which many businesses leave blank — was the highest-impact optimization most clients weren't doing. The services list appears in the GBP under the "Services" tab. It accepts specific service names in free text. Customers who find you through a specific service search — "24 hour locksmith Ottawa" — are often arriving via the services list, not the category.

How to Choose Your Primary Category (The Right Way)

Don't start with what you think Google wants. Start with how your customers describe you. Ask yourself: when a customer in your neighbourhood tells a friend what you do, what do they say? Not the technical industry term — the actual description. "She's a personal injury lawyer" vs. "She's a lawyer." "He's a guy who fixes furnaces" vs. "He's an HVAC technician."

Now go to Google and type that description into a search. See what auto-suggest shows you. See who shows up in the 3-pack. Those businesses are your competition — and their category choices are worth studying.

Your primary category should be the narrowest accurate description of your core service. If you're a "Roofer" that also does "Siding Installation" and "Eavestrough Repair," your primary category is "Roofer" — not "Siding Contractor." Siding goes in secondary. The test: if you stopped offering one of your services tomorrow, would you change your primary category? If no, it's not your primary.

How to Build Your Services List for Maximum Visibility

The services list is underutilized and underoptimized. Here's how to get the most out of it.

List services in the language your customers use, not your industry jargon. "Drain unclogging" not "Hydro jetting and drain cleaning." "Teeth whitening" not "Cosmetic dental procedures." Think about what someone types into Google when they're looking for your service.

Include neighbourhood-specific services if you serve specific areas. If you only service Kanata and Orleans, list "Emergency Plumbing Service Kanata" and "Emergency Plumbing Service Orleans" as separate services. Google matches services to searches geographically.

Be specific enough to match high-intent searches. "Teeth cleaning" is too generic. "Teeth cleaning for sensitive teeth" is specific enough to match a real search intent. "Sofa cleaning" is too generic. "Leather sofa cleaning Ottawa" matches someone with a specific need and a location.

Don't list services you don't actually provide. This seems obvious but it's a real problem. Services you list but don't deliver create a trust mismatch when a customer calls and you can't help them. Only list what you actually do.

Frequently Asked Questions

Q: Can I change my primary category without hurting my existing ranking?

A: Yes — changing your primary category is safe and won't reset your existing review count or rating. It may temporarily shift which searches you appear for as Google re-indexes the change. Usually 2–4 weeks to stabilize.

Q: How many secondary categories should I have?

A: Add all the categories that genuinely reflect services you provide. The maximum is 10 total including your primary. We recommend at minimum 3–5 for most businesses, and up to 9–10 for businesses with genuinely diverse service offerings.

Q: Should my website's service pages match my GBP categories?

A: Yes — consistency between your GBP categories and your website's service page structure sends a strong relevance signal to Google. If your GBP lists "Kitchen Remodeler" but your website has no page about kitchen remodeling, that mismatch hurts you.

Q: What about businesses in Gatineau — does this work differently for Quebec-side businesses?

A: Yes. Gatineau businesses should list categories in French as that's how most Quebec-side users search. Using French-language primary categories on a GBP that's otherwise in English improves local matching for Gatineau searches significantly.

Q: I have multiple locations. Do I need separate GBP categories for each?

A: Yes — each location should have its own GBP with location-specific categories and services. The categories can be identical across locations if the services are the same, but the services list should reflect any neighbourhood-specific offerings or specializations.
