ChatGPT has over 900 million weekly active users. When someone asks it for a recommendation in your industry, does your business come up?
Most companies have no idea. They track Google rankings, check their analytics dashboard, maybe glance at Bing. Whether ChatGPT actually cites them in answers is a black box.
This is a 10-minute diagnostic. Five tests. Each one catches a specific problem that keeps your site out of ChatGPT's answers. Run them in order, and by the end you will know exactly where you stand and what to fix first.
Test 1: The Direct Question Test
What it checks: Whether ChatGPT mentions you at all.
Open ChatGPT and ask it questions your customers would ask. Use their phrasing, not yours. If you sell accounting software for freelancers, do not type "best accounting software." Ask "what is the best accounting tool for a freelance graphic designer?"
Run five to ten questions across different angles. "Who are the top [your industry] companies in [your city]?" "What tools do people use for [your use case]?" "Can you recommend a [your product category] for [specific scenario]?"
Read each answer. Look at the numbered source citations at the bottom. Is your site there?
Track what you find. Queries where you appeared. Queries where competitors appeared instead. Queries where ChatGPT gave an answer with no citations at all.
This is the ground truth. No tool replicates it exactly. ChatGPT personalizes answers based on conversation history and other signals, so your results may differ slightly from someone else's. But if you run ten queries and your site never appears, something is wrong.
Test 2: The GPTBot Crawl Test
What it checks: Whether ChatGPT's crawler can actually read your site.
ChatGPT uses a crawler called GPTBot to discover and fetch web pages. If GPTBot is blocked, your content does not exist in ChatGPT's world. No crawl, no citation.
Check your robots.txt file. Open yourdomain.com/robots.txt in your browser and search for "GPTBot." If you see this:
User-agent: GPTBot
Disallow: /GPTBot is blocked. That is likely your entire problem.
Do not trust the file alone. Test it from a terminal:
curl -A "GPTBot" -I https://yourdomain.com/A 200 response means GPTBot can reach you. A 403 means something is blocking it. The block might be in robots.txt, but it could also be your CDN, a WordPress security plugin, or Cloudflare's bot protection. Check each layer.
To fix a block, add this to your robots.txt:
User-agent: GPTBot
Allow: /If you already have a general Allow: / rule for all user-agents and no specific GPTBot block, you are already open. But verify with the curl test anyway. What is in your robots.txt and what your server actually does can differ.
Test 3: The Content Extraction Test
What it checks: Whether ChatGPT can pull a clean answer from your pages.
GPTBot can crawl your site. Your pages rank well enough to enter ChatGPT's candidate pool. You can still lose if your content is hard to extract.
ChatGPT reads pages like an impatient researcher scanning for the answer. It looks for a heading that matches the question and a direct answer in the first sentence. If your page starts with three paragraphs about your company's mission before getting to the point, the model has to work harder. When a competing page states the same answer more clearly and earlier, that page gets cited instead.
Look at your top pages. For each one, ask: if someone landed here with a specific question, would they find the answer in the first sentence?
The pages that get cited share a pattern. A heading that mirrors the question. A direct answer in the first 40 to 60 words. Specific details below the answer. No fluff before it.
If your pages do not follow this pattern, restructure them. Put the answer first. Move background and context below.
Test 4: The Entity Test
What it checks: Whether ChatGPT understands who you are as a business.
ChatGPT builds profiles of businesses from structured data on their websites. It looks for machine-readable information about your business name, services, location, and identity. Organization schema, local business schema, and other structured data that tells the model "this is who we are."
If that data is missing or inconsistent, the model guesses. Guesses are frequently wrong.
Check whether your site has Organization schema. View your homepage source and search for "schema.org" or "application/ld+json." If you find structured data, check whether it includes your business name, description, and type.
If you do not have it, add Organization schema to your homepage. This is not about rich results in Google. Google deprecated most of those. It is about giving AI models accurate entity data so they do not have to guess.
Test 5: The Competitor Comparison Test
What it checks: Who ChatGPT cites instead of you, and why.
Go back to the queries from Test 1 where competitors appeared but you did not. Visit the pages ChatGPT cited. Compare them to your equivalent pages.
Look for specific differences. Does the competitor answer the question more directly? Is their answer in the first sentence? Do they include specific data points, examples, or named sources that you do not? Is their page faster? Is their heading a closer match to the question?
Write down what you find. If a competitor consistently gets cited because their pages lead with the answer, restructure yours to do the same.
What your results mean
Count how many tests you passed.
Failed Test 1 only: You are not appearing in ChatGPT answers, but your crawl access might be fine. Focus on Tests 3 and 5. Your content may not be specific or well-structured enough to get cited.
Failed Test 2: Fix this first. Nothing else matters if GPTBot cannot read your site. This is the most common problem and the fastest fix.
Failed Tests 1, 3, and 5: Your site is crawlable, but your content is not winning the extraction race. Restructure your pages to lead with answers. Add specific data and examples.
Failed Test 4: You are losing entity accuracy. Add Organization schema. Make sure your business name, type, and description are consistent across your site.
Passed all five: You are in good shape. Check again monthly. ChatGPT's behavior and index change over time.
How this fits the IAB framework
The IAB published "Measuring Visibility in the AI Era" on August 3, 2026. It breaks AI visibility into four dimensions: Presence, Prominence, Portrayal, and Persuasion.
Your five tests map to the first three.
Test 2, the GPTBot crawl test, is Presence. Can ChatGPT find you?
Tests 1 and 5, the direct question and competitor comparison tests, are Prominence. Does ChatGPT pick your page over alternatives?
Tests 3 and 4, content extraction and entity tests, are Portrayal. Can ChatGPT extract a clean, accurate answer from your page?
The IAB also draws a line between directional and decision-grade measurement. Checking your robots.txt is directional. Running ten real queries in ChatGPT and tracking whether you get cited is decision-grade. Test 1 is the closest thing to decision-grade measurement you can do on your own.
Frequently asked questions
Is there a free ChatGPT visibility checker?
There is no official tool from OpenAI that shows whether ChatGPT cites your site. The five tests in this article are the most reliable free method. You can also run a free audit at parceit.com/audit, which checks GPTBot crawlability, structured data, content structure, and every other signal that determines your ChatGPT visibility.
How accurate is manually checking ChatGPT visibility?
It is the most accurate signal available. ChatGPT personalizes answers based on conversation history, so run each query in a fresh chat for the cleanest signal. Ten queries gives you a reliable sample. No automated tool perfectly replicates what ChatGPT shows a specific user at a specific moment.
Why does ChatGPT not mention my business?
The most common causes are a blocked GPTBot crawler (Test 2), low organic rankings that keep you out of the candidate pool, or content that is hard for the model to extract (Test 3). Run all five tests to identify which problem you have.
How is this different from checking Google AI Overviews?
ChatGPT and Google AI Overviews use different retrieval systems. ChatGPT relies on Bing's index plus its own GPTBot crawl. Google AI Overviews use Google's index and the Google-Extended token. You can pass one and fail the other. Check both separately.
How often should I check my ChatGPT visibility?
Monthly. ChatGPT's index changes, your competitors publish new content, and GPTBot re-crawls on its own schedule. What works today may not work next month.
