Does ChatGPT Know My Brand? A 10-Minute Test You Can Run Today

To find out whether ChatGPT knows your brand, ask it five things in a fresh chat: what your business is, how to contact you, who the best providers in your category are, how you compare with a named competitor, and what your customers say about you. The answers show whether it recognises you, describes you correctly and recommends you. Repeat the same prompts in Gemini, Perplexity and Claude, since each engine knows different things.

Before you start: set up a fair test

• Use a fresh session. Open a new chat, ideally logged out or in a private window. ChatGPT memory and past chats about your business can shape the reply.
• Note whether web search is on. With search, the engine reads current pages and usually shows sources. Without it, you see what the model learned in training.
• Keep a simple log. Date, engine, prompt, answer, sources. A spreadsheet is fine.

The 5 prompts that test whether AI knows your brand

1. Recognition: “What is [brand name]?”

Add your city or category if your name is common, for example “What is Brightside Dental in Austin?” You are checking whether the engine knows you exist and puts you in the right category. A vague answer or a mix-up with another company is a sign your entity signals are weak.

2. Accuracy: “How can I contact [brand name]?”

Compare the phone number, website, email and address with your real details. Wrong facts are common when your information differs across directories and old pages. If you find errors, our guide on what to do when ChatGPT has wrong information about your business walks through fixes.

3. Recommendation: “What are the best [category] in [location]?”

This is the one that matters most for new customers, because it does not mention your name. Are you on the list? In what position? Who else is named? Try two or three wordings, such as “best”, “most affordable” and “for small businesses”.

4. Comparison: “[Your brand] vs [competitor]: which is better for [use case]?”

Look at how the engine describes your strengths and weaknesses, and whether it repeats outdated pricing or features. This tells you which facts about you it trusts.

5. Reputation: “What do customers say about [brand name]?”

The engine will summarise reviews and mentions it can find. Note the tone and which review sites it cites. If it says it cannot find reviews, that is a clear gap.

How to read the results

If you are not recommended at all, read why ChatGPT isn’t mentioning your business for the nine most common causes.

An example test log

Here is what one round of the test might look like for a small accounting firm. Keep yours just as simple.

Four rows already give a to-do list: correct the founding year on the About page and LinkedIn, update the old directory listing, and ask the two roundup authors to consider the firm.

Mistakes that make this test misleading

• Testing while logged in. If you have chatted about your business before, memory can make the engine look better informed than it is for strangers.
• Only asking about your brand name. Being known is not the same as being recommended. Prompt 3 matters most.
• Changing the wording every month. Different wording is a different test. Keep a fixed list.
• Ignoring the sources. The cited pages explain both wrong facts and missing recommendations.
• Reacting to one answer. Run each prompt two or three times before deciding anything.

Repeat in Gemini, Perplexity and Claude

Each engine searches different sources and weighs them differently. It is common to be named by Perplexity and missing from Gemini, or the other way around. Run the same five prompts in each and compare. If one engine never mentions you, check that its crawler is allowed in your robots.txt.

Make it repeatable

A manual test is a good start, but answers vary between runs, and five prompts across four engines repeated monthly adds up quickly. Onxeera’s AI visibility checker gives you a quick GEO score across six engines, and Prompt Research asks your real customer questions through each engine’s official API and records mentions, positions and sources over time. If you want to understand the score first, read what a GEO score is.

Frequently asked questions

Why does ChatGPT say it does not know my business?

Usually because there is little clear, consistent information about you on pages it can read: a thin website, few third-party mentions, or blocked crawlers. Newer and smaller businesses are affected most. Clear facts on your own site plus a few trusted profiles are the usual starting point.

Should I test with web search on or off?

Both, if you can. With web search off you see what the model learned in training. With web search on you see what it finds today. Most customers use the default, which in ChatGPT often includes search for questions about businesses and products.

Will asking ChatGPT about my brand many times improve my visibility?

No. Your own chats do not train the public answers other people see. Visibility improves through what is published on the web about you and whether engines can read it.

How often should I repeat this test?

Once a month is enough for most businesses, and again a few weeks after any big change such as a new website, rebrand or press coverage. Use the same prompts each time so results are comparable.
