Primary and secondary categories directly affect which searches your listing appears in. Learn how to choose them well and avoid the most common mistakes.
When it comes to optimizing a Google Business Profile, most business owners focus on photos, reviews, or opening hours. Yet the choice of categories is one of the settings that most directly affects which searches your listing appears in — and it’s often the least carefully considered.
Put simply: if you’ve chosen the wrong primary category, Google associates you with the wrong queries. Your listing exists, but it doesn’t show up when the right people search for what you offer. This article walks you through how to choose, adjust, and get the most out of this frequently overlooked setting.
Categories are standardized labels that Google provides to define the nature of a business. You don’t create them yourself — you select them from a fixed list that Google controls.
There are two levels:
These categories aren’t directly visible to customers browsing your listing, but they guide Google’s algorithm in a meaningful way. It’s a behind-the-scenes setting with real consequences for your visibility.
The primary category is the strongest signal you send to Google about your business identity. It determines:
For example, a business listed as Fine grocery store won’t show up for searches like “event catering” even if it offers that service, because Google has categorized it differently. Choosing Caterer as the primary category would be more relevant if that’s the activity that drives the most revenue or inquiries.
The basic rule: your primary category should reflect the activity for which the vast majority of your customers contact you.
Before locking in your primary category, look at what the businesses ranking first for your target searches are doing. This is a simple, free exercise.
Step 1 — Search your target query in Google. For example: “auto repair shop Montreal” or “hair salon Quebec City.”
Step 2 — Open the listings of the top three businesses in the local pack. Click their name in Google Maps or in the side panel.
Step 3 — Find the category displayed under their name. Google shows the primary category just below the business name in the profile. What you see there is exactly the primary category they’ve chosen.
Step 4 — Note the patterns. If all three top results use “Auto repair shop” rather than “Mechanic,” that’s worth noting. You don’t have to copy them, but it’s useful information.
This analysis takes about fifteen minutes and gives you a concrete basis for your own choice.
This is where things get trickier. Many small businesses offer two distinct families of services. How do you split categories without diluting your positioning?
Guiding principle: one primary category, the most important one.
Ask yourself: If I could only attract ONE type of customer this week, which would it be? That’s your primary category.
Secondary categories cover everything else.
Concrete example — Hair salon with beauty services: - Primary category: Hair salon - Secondary categories: Beauty salon, Nail salon, Day spa
Concrete example — Auto shop with bodywork: - Primary category: Auto repair shop - Secondary categories: Auto body shop, Auto paint shop
Secondary categories let your listing appear in related searches without muddying the signal for your main activity.
Google allows up to nine secondary categories. That doesn’t mean you should use all of them.
Adding categories that don’t genuinely match your services — hoping to capture more searches — is counterproductive for two reasons:
The practical rule: only add categories that correspond to services you actually and regularly provide. One to five relevant secondary categories outperform nine approximate ones.
Here are the most frequently encountered problems:
1. Choosing a category that’s too broad. “Business service” or “Store” are so generic they give Google nothing to work with. Always opt for the most specific category that accurately describes your activity.
2. Choosing a category too far from your main activity. A restaurant owner who selects Caterer as their primary category because they do a few events per year risks missing their everyday restaurant customers.
3. Never reviewing categories. Your offering changes over time. A clinic that added physiotherapy two years ago should have Physiotherapist among its secondary categories. Many listings haven’t been updated since they were first created.
4. Confusing categories with your description. Your profile description (free text field) explains your services in words. Categories serve the algorithm. They play different roles and complement each other.
5. Blindly copying a competitor’s category. A competitor might have a poor category choice too — and still rank well thanks to other strong signals (reviews, seniority, backlinks). Don’t copy without verifying relevance.
The process is quick. Here’s how:
Important note: a change to your primary category can take a few days to produce a measurable effect on your ranking. Avoid changing all your categories at the same time as other major settings — it becomes hard to know which change produced which result.
Choosing your Google Business Profile categories isn’t a one-time decision to set and forget. It’s a living parameter to revisit when your offering changes, and to calibrate based on what your customers are actually searching for.
Key takeaways: - Your primary category should reflect your core activity — the one for which the majority of your customers choose you. - Secondary categories fill out the picture without blurring it — choose them with care, not in bulk. - Analyze your direct competitors to understand the norms in your sector and your area. - Avoid categories that are too generic, too distant from your real activity, or added just to “cover more ground” without genuine relevance. - Review your categories at least once a year, or whenever your offering changes significantly.
