What is ChatGPT search?
SearchGPT, ChatGPT web search
ChatGPT search is the web search capability inside OpenAI's ChatGPT. When a question needs current information, ChatGPT runs searches, reads the results and writes an answer that shows the pages it used as cited sources. OpenAI launched it in October 2024, building on its SearchGPT prototype.
ChatGPT search lets ChatGPT look up current web pages and cite them in its answers.
OpenAI's OAI-SearchBot crawler controls whether your site can appear in ChatGPT search results.
Third-party pages are cited often, so your own site is only one route into the answer.
How ChatGPT search works
ChatGPT search works by deciding when a question needs fresh information, searching the web, and grounding its answer in the pages it finds. ChatGPT can search on its own when a question calls for it, and you can also ask it to search.
A typical ChatGPT search answer follows these steps:
Decide to search: ChatGPT judges that the question needs current or specific information.
Run queries: it turns the question into one or more searches, a pattern known as query fan-out.
Read results: it reads the most relevant pages from its search sources.
Write and cite: it writes an answer with inline citations and a list of sources the user can open.
OpenAI launched ChatGPT search for paid subscribers in October 2024 and opened it to free users in December 2024. The feature grew out of SearchGPT, a prototype OpenAI tested earlier in 2024, which is why you still see that name used.
ChatGPT search vs ChatGPT without search
ChatGPT search differs from a standard ChatGPT answer in where the information comes from. Without search, ChatGPT answers from its parametric knowledge, what the model learned in training, which stops at a knowledge cutoff. With search, it grounds the answer in pages it retrieves at that moment.
Freshness: search answers can reflect a page published last week; training-based answers cannot.
Sources: search answers show citations; training-based answers usually do not.
Your influence: you can affect search answers sooner, because a new or updated page can be retrieved once it is crawled.
For brands, this means two routes into ChatGPT's answers. The slow route is building a strong presence across the web so future models learn about you. The faster route is having pages that ChatGPT search can find and cite today.
How ChatGPT search chooses sources
ChatGPT search chooses sources it can access and that answer the question clearly, but OpenAI does not publish a full list of ranking factors. What you can control is access, clarity and coverage.
Access: OpenAI says sites that block its OAI-SearchBot crawler will not appear in ChatGPT search answers. Blocking GPTBot, its training crawler, is a separate choice and does not by itself remove you from search.
Relevance: pages that answer the specific question directly are easier to cite than broad pages.
Third-party coverage: reviews, comparisons and forum threads are cited often, especially for questions about which product to choose.
Freshness: for time-sensitive questions, recent pages have an advantage.
Note the difference between pages an engine reads and pages it shows. See sources vs citations for why a page can shape an answer without being credited.
How to appear in ChatGPT search
You appear in ChatGPT search by being accessible, quotable and present on the pages ChatGPT already trusts for your topic.
Allow OAI-SearchBot: check your robots.txt and firewall rules so OpenAI's search crawler can reach your pages.
Render content on the server: make key text available in the HTML, not only after JavaScript runs.
Answer questions directly: state facts, prices, features and use cases in short, clear passages.
Earn coverage: find the domains ChatGPT cites for your prompts and work to be included there.
Keep pages current: update facts, dates and comparisons that change.
Track results: run the same prompts over time and watch which pages get cited.
Expect variation. The same prompt can cite different sources on different days, so judge progress by citation rates across many runs.
How KIME tracks ChatGPT search
KIME tracks ChatGPT alongside nine other AI engines, by country and language. Track & Analyze shows how often ChatGPT mentions your brand and competitors for your tracked prompts, where you are placed in the answer and how you are described. You can also see which domains and pages ChatGPT cites, so you know which sources shape its answers in your category.
Frequently asked questions
How do I allow or block ChatGPT search on my site?
Use robots.txt rules for OAI-SearchBot, the crawler OpenAI uses for ChatGPT search. OpenAI says sites that opt out of OAI-SearchBot will not appear in ChatGPT search answers. GPTBot is a separate crawler for model training, so you can block training while still allowing search. Check OpenAI's crawler documentation for current details.
Is ChatGPT search the same as SearchGPT?
SearchGPT was the name of OpenAI's search prototype, tested with a limited group of users in 2024. OpenAI then built search into ChatGPT itself and launched it as ChatGPT search in October 2024. The SearchGPT name is still used informally, but the product today is the search capability inside ChatGPT.
Why does ChatGPT search cite different sources for the same question?
ChatGPT search generates each answer fresh, and the queries it runs, the results it gets and the pages it chooses can change between runs. New content, updated pages and differences in location or conversation context also play a part. Measure citations across many runs of the same prompt rather than relying on one answer.
