On Google, you pick a primary category and back it up with several more. In ChatGPT’s Business Hub, you pick one, and that’s the whole list.
That makes it the hardest choice on the profile for any business that does more than one thing. It also has a trap: the editor shows suggestions that look like extra categories and aren’t.
The rules below are the ones we’d apply to any profile, including our own, where we haven’t settled the choice.

How the category field works
In the About tab, you choose a category from a searchable dropdown. A profile holds one.
Below the dropdown are suggestion chips. On our profile they offered “Software company” and “AI company” while our category was “SaaS company”. We clicked one expecting it to be added. It replaced the category we had.
So before you click a chip, know that you’re swapping, not adding. If you swap by accident, change it back before you save.
How to choose
Work through these in order.
1. Start with what brings in most of your revenue
If you’re a dental practice that also does cosmetic work, you’re a dentist. The single category should describe the business a customer would recognize, not the service you’d like to sell more of.
2. Match your Google category where the same option exists
Consistency across listings is one of the few practices that holds up everywhere. If your Google primary category has a matching option in ChatGPT, that’s a sound default.
If you’re not sure your Google category is right in the first place, check what comparable businesses use. In Rankability, the Google Business Profile Auditor includes a Competitors tab that shows the businesses returned in the local map results for your keyword, with their category where it’s available. That’s a search snapshot for one keyword and location, so use it as evidence, not a rule.
3. Prefer the specific option only when it’s accurate
We had “SaaS company”. Google lists us as “Software company”. The specific label describes us more precisely, and the broader one matches our Google listing.
Nobody knows yet whether specificity helps in ChatGPT. We’d lean toward matching Google, because consistency is the principle we can defend. It’s a judgment call, and we haven’t made the switch ourselves. Our category is still “SaaS company” while we decide.
4. Don’t choose a category for the keyword
A category you don’t really fit is a mismatch a customer will notice the moment they open your profile. It also puts you out of step with every other listing you have.
What the category list looks like
The code that the Business Hub page loads includes the full category list. When we read it on November 11, 2026, it held 848 categories, each with a written description, grouped into 21 areas. They run from technology, finance, health, and food and drink through to real estate, retail, automotive, manufacturing, travel, and personal services.
The list may already be changing. David Konitzny, who found the category list in the page code before we did, counted 128 category families. We counted 136. If a category you expected isn’t there, search for a near match, and check again in a few weeks.
After you choose
- Save, then reopen the About tab and confirm the category is the one you picked.
- Check that your description supports it. A “Dentist” category with a description about teeth whitening only sends a mixed message.
- Note the category and date somewhere. If the list changes, you’ll want to know what you had.
A services section isn’t in the editor, so the category and the description are the only places you can say what you do. See how to write a ChatGPT business description for the other half, and our complete guide to ChatGPT business profiles for everything else.

Sources and method
The single-category limit and the chip behavior are what we saw on Rankability’s own profile on November 11, 2026. The category count and the 21 areas come from the code the Business Hub page loads in the browser, read the same day. Code shows what has been built, which isn’t always what is switched on, and it can change without notice. OpenAI has published no guidance on how the category affects which businesses ChatGPT recommends.
