You paste your business description into ChatGPT’s Business Hub, click save, and it says “Saved”. What it doesn’t say is that everything past 300 characters is gone.
That happened to us. The field cuts text off at 300 characters with no warning, and it’s one of several limits that Business Hub enforces without telling you.
We recorded each one while setting up Rankability’s profile, along with what to do about it.

The limits at a glance
| Field | Limit | What to do |
|---|---|---|
| Business name | Couldn’t be edited after claiming | Claim under your real name |
| Category | One only | Pick the best single fit |
| Description | 300 characters, cut off silently | Count first, read it back after |
| Photos | Cropped to a square from the centre | Upload squares, subject centred |
| Photo files | JPEG, PNG, GIF or WebP, 10 MB each | Compress large images |
| Logo | No field in the editor | Add your logo as a photo |
| Address | No option to hide it | Match it to your site exactly |
| Product feed file | 20 MiB per upload | Use a hosted URL for larger catalogs |
| Product images | JPEG or PNG links only | Convert WebP before listing |
The description stops at 300 characters
Google Business Profile allows 750 characters. ChatGPT allows 300, spaces included.
The field doesn’t show a counter and doesn’t reject long text. It keeps the first 300 characters and drops the rest. We approved a longer description, saved it, and found it trimmed.
What to do: write to 300 from the start, count it before you paste, and read the saved text back. Our guide to writing a ChatGPT business description has examples that fit.
You get one category
A profile has a single category, chosen from a searchable dropdown.
Under the dropdown are suggestion chips, such as “Software company” and “AI company”. They look like extra categories you can add. They aren’t. Clicking one replaces your current category.
What to do: decide on one category before you open the editor. See how to choose your ChatGPT business category.
The business name is fixed
We couldn’t edit the business name in any of the five editor tabs. Whatever you claim under is what you keep, as far as we can tell.
What to do: claim under the name on your website and signage, with no keywords, cities, or taglines added.
Photos are cropped to squares
Photos display as square tiles, cropped from the centre. A wide screenshot loses its left and right edges, which is exactly what happened to ours.
Two more things the editor doesn’t tell you:
- The first photo is the cover. Reorder with the arrows.
- There’s no logo field in the editor. Add your logo as a photo.
The page code that Business Hub loads does state file limits: JPEG, PNG, GIF, and WebP, up to 10 MB per photo. It also names a logo field and a cover photo field that weren’t in the editor when we checked.
What to do: upload square images of 1080 by 1080 pixels or larger, with the subject in the centre. Details are in our ChatGPT profile photo guide.
The address is public
We saw no option to hide the address or set a service area. The public profile shows a Get directions button, which opens a map search for your address, even for an online-only software company.
What to do: make sure the address matches your website and Google listing exactly, including how the unit is written. Ours read “900” on the profile and “Suite 900” in our site’s schema.
Product feeds have their own rules
- File size: an uploaded file can be up to 20 MiB. A gzip file must also be 20 MiB or smaller once decompressed.
- Images: product images must be direct links to a JPEG or PNG. WebP isn’t accepted in feeds, even though profile photos accept it.
- Uploads don’t update. A file you upload stays as it is. If prices change, you need a new file, a hosted URL, or SFTP.
The full list of fields is in our guide to adding products to ChatGPT with a product feed.
Limits that belong to the platform, not to you
Some things we couldn’t change: the business name, the public address, and the Get directions button. If you’re auditing a profile, note those as platform limits and don’t mark the business down for them.
Everything else here is within your control, and most of it takes minutes. For the full setup order, see our complete guide to ChatGPT business profiles.

Sources and method
We recorded these limits on Rankability’s own verified profile on November 11, 2026. The photo file limits and the logo and cover fields come from the code the Business Hub page loads in the browser, which shows what has been built and not always what is switched on. The feed limits are from the upload screen and OpenAI’s product feed documentation. Businesses in ChatGPT is in beta, so limits can change.
