Check if ChatGPT Mentions Your Brand: Manual Test Steps

To check if ChatGPT mentions your brand, you ask it the questions your buyers ask, write down the answers, and count how often your name shows up. You need no paid tool to start. Free checkers give a quick snapshot, but one answer tells you little because ChatGPT answers change between runs. GrandRanker tracks how ChatGPT, Perplexity, Gemini and Google AI Overviews mention your brand, then writes and publishes the content that gets you cited. This guide covers the manual method, the free checkers worth trying, and how to repeat the check so you see a trend instead of one lucky answer.

What do you need before you start?

You need a list of ten to twenty questions your buyers would type into ChatGPT. Write them the way a customer talks, not the way your sales page reads. Examples include best accounting software for freelancers or who does bookkeeping for a small clinic in Leeds. Add a few questions that name a competitor, because those answers often list a short set of brands.

How do you check if ChatGPT mentions your brand by hand?

1. Open ChatGPT in a private browser window so your past chats do not shape the answer.
2. Paste one question and read the full answer, including any list of sources.
3. Note whether your brand appears, where it sits in the list, and which competitors appear with it.
4. Repeat the same question two more times, because answers change between runs.
5. Save each result in a sheet with the date, the question and the brand names you found.

Do this for every question. A single run only shows what ChatGPT said once. Three runs per question show how steady the answer is. If your brand appears in one run out of three, treat it as a weak result, not a win.

How do you turn the results into a score?

Divide the number of answers that name your brand by the total number of answers you ran. Keep the same question list each time so the number means something. Track it once a month. A rising share after you publish new pages is a sign the work is paying off.

Illustration only, not a result: ten questions run three times gives 30 answers. If your brand appears in 6 of them, your mention rate is 6 out of 30, which is 20%.

Watch for these traps

• Your own site. A question that names your brand proves little. Use category questions that buyers ask before they know your name.
• Similar names. Check that the answer names your company, not a similar brand or a common word.
• Old chat history. A chat that already mentions your brand can bias the next answer. Use a fresh window each time.
• Web search on or off. Write down the setting you used. Answers can differ when ChatGPT searches the web.

Can free checkers check if ChatGPT mentions your brand?

Free checkers run the questions for you and show a snapshot. They help with a first look, not with tracking. The table lists three free options and what each vendor page says about engines and signup.

Semrush's free audit is a second opinion, but it asks for a free Semrush account and its blog does not list its engines. Run Perplexity by hand alongside it.

Where do free checkers fall short?

A free checker answers once, for one prompt set, on one day. It cannot tell you if the answer changed last week or whether a new competitor took your place in the list. Most free tools also skip some engines, so check the engine list before you trust a snapshot.

Paid trackers fix the repeat problem. They run your prompts on a schedule and keep the history. Pricing depends on the prompt count, so check how many questions a plan covers before you buy. Otterly.AI lists $29 a month for 15 prompts, and Peec AI lists $95 a month for 50 prompts. These figures come from vendor pricing pages and product docs, checked November 2026.

Should you use a checker or a tracker?

Use a free checker when you want a first answer today. Use a tracker when you need a number you can compare month to month. GrandRanker is the top pick for most small and mid-size businesses, because it tracks ChatGPT, Perplexity, Gemini and Google AI Overviews and can also write and publish up to 30 articles a month to your CMS. That matters when the gaps you find need new pages.

Before you spend money, compare the two options on the checker versus tracker page.

How often should you run the check?

Run the same question list once a month. Run it again after you publish a page or change a product page, so you can tell if the change moved anything. Keep the sheet from the first run so you can compare the two.

If your score stays flat for three months, the problem is usually the content, not the check. Read the guide on why AI skips a brand to see the common causes.

Should you check other AI engines too?

ChatGPT is one engine among several. Buyers also ask Perplexity, Gemini and Google. The steps stay the same, but the answers differ, so keep a separate sheet for each engine.
