ChatGPT
OpenAI's conversational AI with web browsing, plugins and custom GPTs. Answers draw on both training data and live search, so visibility depends on how your brand is represented in the corpus and on what the live index surfaces at query time.

How ChatGPT retrieves information
ChatGPT operates in two modes: a knowledge cutoff model and a browsing-enabled model. When browsing is active, ChatGPT issues search queries via Bing, evaluates results, fetches page content and synthesizes answers with inline citations.
The retrieval pipeline processes pages through multiple stages: query generation, search execution, result ranking, content extraction and citation attribution. At each stage, signals like domain authority, content structure, entity clarity and freshness influence whether a source is selected.
Plugins extend ChatGPT's retrieval to specialized data sources. Custom GPTs allow brands to define their own knowledge bases, but standard browsing citations still depend on the core retrieval signals.
Relevant crawlers
ChatGPT's browsing relies on Bing's crawler infrastructure. The primary bots to monitor:
- bingbot
Bing's primary crawler — powers ChatGPT's web browsing results.
- GPTBot
OpenAI's crawler for training data and content understanding.
- ChatGPT-User
User-initiated browsing requests — triggered when ChatGPT searches for a query.
Example answer structure
"According to [Source Name], [synthesized answer with key facts]. [Additional context from another source]. [1] [2]"
Sources: [1] example.com/article [2] authority-site.com/guide
ChatGPT typically displays 2–5 inline citations as numbered references. Citations are clickable links to the source pages. The answer text is synthesized from multiple sources, not copied verbatim.
What matters for ChatGPT visibility
Entity Signals
Clear entity identification through Schema.org markup, consistent NAP data and explicit brand-to-topic relationships help ChatGPT understand what your content is about and when to cite it.
Bing Authority
Since ChatGPT uses Bing for search, your Bing Webmaster Tools signals matter. Bing Places, Bing indexing and backlinks from Bing-indexed domains all contribute to citation likelihood.
Content Structure
Pages with clear heading hierarchy, concise definitions, and structured answer-format content are more likely to be extracted and cited. ChatGPT favors content that can be summarized accurately.
Freshness Signals
Recent publication dates, updated timestamps and regularly refreshed content signal relevance. ChatGPT's browsing prioritizes current information for queries where recency matters.

Answers
Frequently asked questions
How does ChatGPT decide which sources to cite?
ChatGPT's browsing mode evaluates source authority, content freshness, topical relevance and structured data when selecting citations. Pages with clear entity signals, Schema.org markup and authoritative backlink profiles are cited more frequently.
Does ChatGPT use Bing or Google for web search?
ChatGPT uses Bing as its primary web search provider when browsing. This means Bing indexing and Bing's authority signals directly influence whether your content appears in ChatGPT's cited sources.
What structured data matters most for ChatGPT visibility?
Organization, Article, FAQPage and Product schemas are the most impactful. ChatGPT's retrieval pipeline parses structured data to understand entity relationships and content hierarchy, which influences citation selection.
How are custom GPTs different from standard ChatGPT answers?
Custom GPTs can be configured with specific knowledge bases and browsing capabilities. Brands can create their own custom GPTs to control how their information is presented, but third-party citation still depends on standard retrieval signals.
