ChatGPT Browse uses two separate bots — GPTBot for training and ChatGPT-User for real-time browsing. Here's how to optimise for both and get cited in live answers.

ChatGPT crossed 300 million weekly users in 2025. A growing proportion of those users ask it questions with Browse enabled — questions about the latest tools, current pricing, recent articles, and what a specific company or product does today. For those queries, ChatGPT doesn't answer from its training data. It searches the web in real time, selects sources, reads them, and synthesises a cited answer.
If your site is not configured to be found by ChatGPT's browsing infrastructure, you are invisible to every one of those queries — regardless of how well you rank in Google.
This guide explains exactly how ChatGPT Browse works, what makes it choose one source over another, and the specific technical and content steps that make your site a reliable citation target.
ChatGPT Browse is not a monolithic crawl. It is a two-stage process that combines a Bing-sourced candidate list with a real-time direct crawl of selected pages.
Stage 1: Bing search
When ChatGPT Browse is triggered, OpenAI's backend issues a search query to Bing. The search query is usually a reformulated version of the user's question — not the literal question but a cleaned-up, search-friendly version. Bing returns a list of candidate URLs based on its normal ranking algorithm.
This means that Bing indexing is not optional for ChatGPT Browse visibility. It is the filter that determines which pages are even considered. A site that exists only in Google's index — and has never been indexed by Bing — will not appear in ChatGPT Browse results, regardless of its content quality.
Stage 2: Direct crawl via ChatGPT-User
From the Bing candidate list, ChatGPT selects a subset of URLs and sends the ChatGPT-User bot to crawl them directly. This is a real-time HTTP request to your server. ChatGPT-User reads the current page content — not a cached version, not Bing's snapshot, but what your server returns at that moment.
The AI model then reads the crawled content, extracts the most relevant information for the query, and synthesises a cited answer. The citation links shown in ChatGPT's response are the pages whose crawled content was used in the synthesis.
OpenAI operates two distinct crawler user-agents, and they serve fundamentally different purposes.
GPTBot (Mozilla/5.0 AppleWebKit/537.36 ... GPTBot/1.1)
GPTBot is OpenAI's training crawler. It crawls the web to build datasets used to train future versions of ChatGPT's underlying models. When GPTBot reads your content, it is contributing to what the model "knows" at a knowledge level — not what it retrieves in real time.
Blocking GPTBot in robots.txt means your content is excluded from future model training. This affects how ChatGPT answers questions about your domain or topic from its baked-in knowledge, not from Browse. For most sites, this is the less immediately consequential of the two bots.
ChatGPT-User (Mozilla/5.0 AppleWebKit/537.36 ... ChatGPT-User/1.0)
ChatGPT-User is the Browse crawler. It fires in real time when a user has Browse enabled and ChatGPT decides to retrieve a page. Blocking ChatGPT-User means ChatGPT cannot read your page during Browse — even if Bing returns your URL as a top result, the crawl will be rejected, and ChatGPT will move on to the next candidate.
robots.txt configuration to allow both:
User-agent: GPTBot
Allow: /
User-agent: ChatGPT-User
Allow: /
If your robots.txt currently has a blanket disallow (User-agent: * Disallow: /) applied to some paths, verify that neither GPTBot nor ChatGPT-User is caught by it. A wildcard disallow for authenticated or app paths is fine — just ensure your public content paths are explicitly allowed.
Check the full list of AI crawler user-agents and correct robots.txt patterns in our robots.txt guide for AI crawlers.
ChatGPT does not use Browse for every query. The model decides whether to invoke Browse based on whether real-time information is likely to improve the answer. The trigger patterns are consistent and learnable:
Explicit recency signals
Date references Any query that references a specific date, year, or timeframe that falls near or after the model's training cutoff triggers Browse. Queries like "What is [product] pricing in 2026?" consistently trigger Browse even if the price hasn't changed.
Current events and news Anything that could reasonably be expected to have changed since training — product releases, algorithm updates, policy changes, company news — typically triggers Browse.
Direct company or product queries Queries like "What does [company] do?" often trigger Browse when the company is small or specialised enough that the training data is sparse. For niche B2B SaaS products, many user queries will Browse to verify or supplement what the model knows.
Queries with "now", "today", "this week" These explicit temporal markers almost always trigger Browse.
If your target audience asks questions with any of these patterns, Browse-optimised content is directly relevant to your traffic.
Within the Browse flow, after Bing returns candidates and ChatGPT-User crawls the selected pages, how does ChatGPT decide which content to cite?
Bing ranking is the primary filter
The strongest predictor of Browse citation is Bing ranking position. Pages that rank in Bing positions 1–5 for the reformulated query are far more likely to be crawled and cited than pages ranking below position 10. Bing SEO and Google SEO are largely the same — title tags, backlinks, content quality, and page experience — but there are Bing-specific factors worth noting: Bing weighs exact-match anchor text more heavily than Google, and Bing's Webmaster Tools submissions can accelerate indexing for new content.
Content structure at crawl time
Once ChatGPT-User retrieves your page, the model reads it and extracts relevant information. Pages that answer the query directly — with the core answer appearing early in the content, in a clear sentence or paragraph — are more likely to be cited verbatim. Pages that bury the answer after long introductions, preambles, or navigation-heavy layouts are harder for the model to extract from.
Structural signals that improve Browse extraction:
Freshness
Browse has a demonstrable freshness preference. For equivalent content quality and Bing ranking, a page published or modified in the last 30 days consistently outperforms older pages in Browse citation frequency. The implication: updating existing content with new data, a fresh date, and revised examples has Browse-visibility benefits beyond the traditional SEO benefit of freshness.
Domain authority signals
Browse inherits Bing's domain authority signals. Sites with strong Bing backlink profiles and consistent crawl history are treated as more reliable sources. For niche SaaS products and specialist content publishers, this means building backlinks from sources that Bing indexes well — not just publications that Google prioritises.
Submit your sitemap to Bing Webmaster Tools at bing.com/webmasters. This is separate from Google Search Console and is the most direct way to confirm Bing has your pages. Google Search Console does forward indexing signals to Bing in some cases, but direct Bing Webmaster Tools submission is faster and more reliable.
After submitting, use Bing's URL Inspection tool to verify that your key pages are indexed. For new or recently updated content, use the "Submit URLs" feature to request immediate indexing rather than waiting for the next crawl cycle.
As shown above, add explicit Allow rules for both GPTBot and ChatGPT-User. Check your current robots.txt by visiting yourdomain.com/robots.txt directly. If you're running Next.js, robots.txt is typically generated from app/robots.ts — add both user-agents there.
For every piece of content targeting a Browse-triggered query (anything with "latest", recency references, or current information), rewrite the first paragraph of each major section as a direct, self-contained answer to the section heading's question. A reader should be able to understand the core answer from the first two sentences without reading the full section.
This structure serves double duty: it improves AI citation for Browse, and it improves featured snippet eligibility in Google.
Refreshing a page solely by changing the modified date without substantive content changes does not reliably trigger Browse's freshness preference — Google has confirmed this, and the same likely applies to Bing's signals. Meaningful updates include: new statistics, revised pricing, updated examples, added sections, removed outdated information.
For long-form SEO content, a quarterly review and update cycle — adding a section for each year's developments — creates a strong freshness signal without requiring a full rewrite.
ChatGPT's Browse synthesis favours pages where it can clearly attribute the information to a named author and a dated publication. Use Article schema with datePublished, dateModified, and a named author with credentials. The Article schema guide covers the exact implementation.
You do not need to guess whether ChatGPT can find and cite your site. Test it directly:
Test 1: Domain knowledge Ask ChatGPT (GPT-4 with Browse enabled): "What does [yourdomain.com] do?"
A good result: ChatGPT describes your product accurately based on crawled content and cites your homepage or about page. A bad result: ChatGPT says it doesn't have information about the site, or describes it inaccurately based on training data only.
Test 2: Content discovery Ask: "What are the latest articles on [your topic] from [yourdomain.com]?"
A good result: ChatGPT lists recent posts with titles, dates, and links. A bad result: "I don't have access to recent articles from that site" — indicating ChatGPT-User is blocked or the site isn't Bing-indexed.
Test 3: Query interception Ask a question that your best content should answer — for example, if you have a guide on robots.txt for AI crawlers, ask "How do I allow ChatGPT to crawl my site in robots.txt?"
A good result: your page is cited in the response. A bad result: competitors are cited instead — indicating either a Bing ranking gap or a content structure problem.
Run these tests from a fresh ChatGPT session with Browse explicitly enabled (use GPT-4 and confirm the Browse toggle is on). Document baseline results before making changes so you can measure improvement.
Browse optimisation is one component of a broader Generative Engine Optimization (GEO) strategy. The fundamentals — structured content, named authors, clear answers, fresh information — apply across ChatGPT Browse, Perplexity, and Google AI Overviews alike.

Does blocking GPTBot affect ChatGPT Browse?
No. Blocking GPTBot prevents OpenAI from using your content for model training, but it does not prevent ChatGPT-User from browsing your pages in real time. You can block GPTBot while allowing ChatGPT-User if you want Browse visibility without contributing to training data.
How quickly does ChatGPT Browse pick up new content?
Browse retrieves pages at the time of the query — it is real-time. However, the Bing index needs to have the page first. Bing's crawl cycle is typically 1–14 days for sites with active Bing Webmaster Tools submissions. Submit new URLs directly via Bing Webmaster Tools to accelerate this.
Does ChatGPT Browse work differently for paid ChatGPT Plus vs free users?
Browse is available to ChatGPT Plus subscribers and in some free-tier configurations. The crawl and citation mechanics are the same regardless of the user's subscription tier — the difference is access to the feature, not how it processes pages.
Can I see when ChatGPT-User has crawled my site?
Yes — check your web server access logs for the ChatGPT-User user-agent string. Most log analysis tools (Google Analytics, Cloudflare analytics, server access logs) can filter by user-agent. Frequent ChatGPT-User hits on a page indicate it is being actively retrieved for Browse queries.
