Where does ChatGPT search get its results?

OAI-SearchBot crawls so that sites can be surfaced in ChatGPT search[1], but no page the researcher could read says whether results come from an OpenAI index, from third-party search providers or from both. The web search tool guide names no provider[2]. The help center pages that reportedly cover providers returned HTTP 403[6, 9, 14], so whether it runs its own index is recorded as unknown.

Engines that use results from ChatGPT search

The research records no engine that takes its general results from ChatGPT search or is built on it by the same company.

Does ChatGPT search use structured data?

Stance recordedIts pages say nothing about it

No OpenAI page the researcher could read says whether ChatGPT search reads on-page structured data. The crawler page[1] and the web search guide[2] do not mention it, and the commerce docs describe only a merchant feed[4, 5].[1]

Other formats and channels

  • OpenAI product feedDocumented

    A merchant product feed sent to OpenAI, not on-page markup. JSONL in the examples; CSV and TSV are referenced. Delivery is by API or SFTP file upload[3, 5].[4]

Which rich results can ChatGPT search show?

The research records 1 rich result type for ChatGPT search: 1 limited. Each entry shows the schema.org types it is documented for, where the research records them. Valid markup can make a page eligible; it does not guarantee the result.

Limited 1

  • Product feed for product discovery in ChatGPT (Agentic Commerce) Limited

    Documented for: no schema.org type recorded

    Required: availability, brand, description, image_url, item_id, price, seller_name, title, url

    Where: not stated

    Formats: OpenAI product feed

    These are feed fields, not schema.org properties and not on-page markup. The spec lists the remaining fields under one recommended or optional heading without a split, so recommended is left empty (see the vocabularies listed below). Onboarding is limited to approved partners[5]. The standard upload currently targets the US; other markets need OpenAI to confirm the integration, countries and currencies[4]. Search eligibility is on by default; checkout and ads need separate enablement[4].

    Documentation[4]

How does ChatGPT search crawl the web?

The research lists 4 crawler tokens for ChatGPT search: the names a site uses in robots.txt rules, with what each one does where the source says.

  • OAI-SearchBot

    Search crawler. Surfaces websites in ChatGPT search results. A variant user agent with a robots.txt marker is used when fetching robots.txt files. follows robots.txt.[1]

  • GPTBot

    Training crawler. Collects content that may be used to train OpenAI's generative AI foundation models. follows robots.txt.[1]

  • OAI-AdsBot

    Ads crawler. Visits pages submitted as ChatGPT ads to check landing page safety. robots.txt behavior not stated.[1]

  • ChatGPT-User

    User-triggered fetcher for actions in ChatGPT and Custom GPTs, including GPT Actions. Not an automatic crawler. may ignore robots.txt (fetches a person asked for).[1]

How do I test my markup for ChatGPT search?

The research records no markup testing tool of its own for ChatGPT search.

What does ChatGPT search ask of site owners?

Guidelines

robots.txt
Each OpenAI token is controlled separately in robots.txt. A robots.txt change takes about 24 hours to affect search results.[1]
search inclusion
OAI-SearchBot is the token for ChatGPT search. OpenAI recommends allowing it. A site that blocks it is not shown in ChatGPT search answers but can still appear as a navigational link.[1]
training
GPTBot crawls content that may be used to train OpenAI's generative AI foundation models; disallowing it signals that the content should not be used for training. If a site allows both OAI-SearchBot and GPTBot, one crawl may serve both.[1]
user fetch
ChatGPT-User acts on user requests in ChatGPT and Custom GPTs, including GPT Actions. It is not an automatic crawler and does not decide whether content appears in search. The page says robots.txt rules may not apply to it.[1]
ads
OAI-AdsBot visits only pages submitted as ChatGPT ads, checks landing page safety and may use landing page content to decide when to show the ad. OpenAI says the data is not used to train generative AI foundation models. The page does not say how robots.txt applies to this token.[1]
structured data
The crawler page does not mention structured data, schema.org, sitemaps, noindex or any meta tag.[1]
feeds
OpenAI's commerce guide says the product feed gives ChatGPT the data it needs to index products. It mentions no crawling and no on-page structured data. A full snapshot at least once a day is recommended, and onboarding is open to approved partners only.[5]
citations
API web search answers carry url_citation annotations with URL, title and location. OpenAI requires inline citations to be clearly visible and clickable. A sources field lists every URL consulted. Developers can pass up to 100 allowed domains or up to 100 blocked domains.[2]

Its own vocabularies, tags and feeds

  • OpenAI product feed spec

    Merchant feed format for product discovery in ChatGPT. Nine required fields: item_id, title, description, url, brand, seller_name, image_url, availability, price. Further fields are listed as recommended or optional without a split: group_id, listing_has_variations, variant_dict, offer_id, gtin, mpn, condition, product_category, material, color, size, gender, age_group, dimensions, length, width, height, dimensions_unit, weight, item_weight_unit, additional_image_urls, sale_price, seller_url, shipping_price, shipping, accepts_returns, return_deadline_in_days, return_policy, review_count, star_rating, is_eligible_search, is_ads_eligible, ads_metadata, is_eligible_checkout, seller_privacy_policy, seller_tos, target_countries, store_country, marketplace_seller, size_system, store_review_count, store_star_rating, accepts_exchanges, is_digital. The page does not mention schema.org.[4]

  • Agentic Commerce Protocol (ACP)

    OpenAI's commerce developer docs: product feeds delivered by API or SFTP, plus the Agentic Checkout Spec, the Delegated Payment Spec and the Promotions API. Feeds are the only product discovery channel the docs name.[3]

What could not be verified?

These claims about ChatGPT search came up in the research, but no page that could be read confirms them. They are kept apart, and nothing above rests on them.

  • ChatGPT search works with third-party search providers, and Enterprise and Edu workspaces reportedly send disassociated queries to Bing.

    Why it is open: Blocked fetches. A search snippet is not a fetched primary page, and no OpenAI page that loaded names a search provider.

    How it was checked

    Fetched the help center article on ChatGPT search[6], the Enterprise and Edu search article[9] and the launch blog post[10]. All returned HTTP 403. The claim comes from a web search result summary only.

  • OpenAI's publishers and developers FAQ reportedly advises allowing OAI-SearchBot and tracking ChatGPT referrals in analytics.

    Why it is open: Blocked fetch. The guidance could not be read on OpenAI's own page.

    How it was checked

    Fetched source 7. HTTP 403. The claim comes from a web search result summary only.

  • ChatGPT shopping results read on-page structured data in addition to merchant feeds.

    Why it is open: Blocked fetches. The pages that loaded neither confirm nor deny any use of on-page markup.

    How it was checked

    Fetched the shopping help article[8] and the product discovery page[11]. Both returned HTTP 403. The commerce developer docs that loaded[3-5] describe only the feed.

  • In HIPAA-eligible workspaces ChatGPT search reportedly uses OpenAI's own search index.

    Why it is open: Blocked fetch. This bears on whether it runs its own index, which stays unknown until the page can be read.

    How it was checked
