Citations and product results are different

A citation is a web page ChatGPT links as a source when it searches the web. A product result is a product card with images, price and merchant links, built from structured product data. This page is about citations. For product results, see the ChatGPT shopping product data checklist.

How ChatGPT search finds pages

OpenAI documents several crawlers, and they do different jobs. OpenAI crawler documentation

CrawlerWhat it is forWhat blocking it means
OAI-SearchBotSurfacing websites in ChatGPT searchYour pages are kept out of search answers, though they may still appear as navigational links
GPTBotCollecting data for model trainingOpts out of training only; separate from search
ChatGPT-UserFetching a page when a user asks ChatGPT toOpenAI notes robots.txt rules may not apply; not used to decide search inclusion

OpenAI says robots.txt changes for OAI-SearchBot take about 24 hours to apply. When ChatGPT answers without searching, it draws on what the model learned in training, which you cannot update directly.

What to check on your product pages

How to measure citations

  1. Fix a question set. Write realistic buyer questions for your category and keep them the same between rounds.
  2. Record the conditions. Date, language, region, the model or product used, and whether web search was on.
  3. Save the answers. Keep the answer text and the cited sources, not just a yes or no.
  4. Count mentions consistently. Decide in advance what counts: your brand, model name, or URL.
  5. Repeat on a schedule. Answers change over time, so one round is a snapshot, not a result.
  6. Keep sources of data apart. Answers from a model's API can differ from what people see in the ChatGPT app, and one engine's results do not stand in for another's.

With small question sets, treat changes as signals to investigate rather than proof of cause and effect.

Common mistakes

Where Hasmord helps

Hasmord's citation checks ask AI models realistic buyer questions through their APIs — up to four models, depending on your plan — and save the answer text with whether it mentioned your brand, model or URL. The product data audit and evidence checks help with the page side. API answers can differ from the ChatGPT app, so Hasmord reports them as observed.

Frequently asked questions

How does ChatGPT find pages to cite?

When ChatGPT searches the web, it uses pages that OpenAI's search crawler, OAI-SearchBot, can access. Blocking OAI-SearchBot keeps a site out of search answers.

Does blocking GPTBot stop ChatGPT from citing my site?

According to OpenAI, GPTBot is used for model training and is separate from search. Search inclusion depends on OAI-SearchBot.

Can I make ChatGPT cite my product?

No one can guarantee it. You can make your pages accessible, specific and backed by sources, then measure citations over time.

How do I know if ChatGPT cites my brand today?

Ask a fixed set of realistic buyer questions, record the date and conditions, save the answers and sources, and repeat on a schedule.

How long until ChatGPT reflects changes to my page?

It varies. OpenAI says robots.txt changes take about 24 hours to apply; recrawling and how answers change are not on a fixed schedule.
