When someone asks ChatGPT “what's the best tool for…”, it usually names three to five brands. Getting onto that list isn't luck. It comes down to whether ChatGPT can find you, whether the sources it trusts mention you, and whether your own pages answer the question clearly.
For questions about products and vendors, ChatGPT typically searches the web before it answers. It sends a handful of search queries, reads the results, and writes a response that cites some of those pages. What the model learned in training still shapes the framing, but the live search is where most brand recommendations come from.
The practical consequence: if the pages ChatGPT reads for “best [your category]” don't mention you, ChatGPT won't either.
OpenAI says ChatGPT search draws on third-party search providers alongside its own crawling and content from publishing partners. Bing is widely understood to be one of the main providers, which is why strong Bing visibility tends to go hand in hand with ChatGPT visibility. OpenAI's own crawler for search, OAI-SearchBot, adds pages to the pool ChatGPT can surface.
In practice, the sources ChatGPT cites for commercial questions fall into a few groups:
Listicles and comparison articles, such as “best X tools in 2026” posts on editorial and vendor sites.
Review platforms and directories like G2, Capterra and category-specific marketplaces.
Community discussions, especially Reddit threads where people compare options.
Vendors' own pages, mainly product, pricing and comparison pages that state facts plainly.
Start with the prompts a buyer would type, not your keyword list. Mix category prompts (“best AI visibility tools for agencies”), problem prompts (“how do I see if ChatGPT mentions my brand”) and comparison prompts (“Semrush vs Profound”). Run each one repeatedly, since answers vary between runs, and record whether you're mentioned, in what position and next to which competitors.
OpenAI runs separate crawlers for separate jobs, and blocking the wrong one can quietly remove you from ChatGPT search results.
OAI-SearchBot indexes pages for ChatGPT search. Blocking it is the fastest way to disappear from ChatGPT's answers.
ChatGPT-User fetches a page when a user's conversation needs it in real time.
GPTBot collects content that may be used to train OpenAI's models. You can block it and still appear in search answers.
The searches ChatGPT runs behind the scenes, its query fan-out, tell you exactly which queries you need to rank for. The pages it cites tell you which publications, review sites and Reddit threads it trusts in your category. Together they're a precise content and outreach plan.
ChatGPT favors content that states things plainly. For the prompts where you're missing:
Lead with a direct answer in the first two sentences, then expand.
Use specific numbers, named features and clear “best for” statements.
Publish honest comparison pages against the competitors ChatGPT names instead of you.
Keep pricing, integrations and feature pages current and crawlable as plain HTML.
Your own site is only one source. Get listed on the review sites and directories that show up in your citations, contribute genuinely useful answers to the Reddit threads ChatGPT quotes, and close the link gap with competitors who are recommended more often. Then re-measure: visibility should move within a few weeks of new sources being indexed.
Because ChatGPT search leans on third-party indexes, pages that aren't indexed by Bing are at a disadvantage. Verify your site in Bing Webmaster Tools, submit your sitemap, and use IndexNow so new and updated pages are picked up quickly. Check that important pages actually appear in Bing results for their main queries.
Before you invest in new content, make sure the basics are in place:
OAI-SearchBot and ChatGPT-User are allowed in robots.txt and not blocked by your CDN or firewall.
Your site is verified in Bing Webmaster Tools with a current sitemap.
Product, pricing and comparison pages render as plain HTML without needing JavaScript.
Your homepage and product pages say clearly what you do, who it's for and what it costs.
You're listed, with accurate details, on the review sites and directories ChatGPT cites in your category.
You track a fixed set of prompts over time, so you can tell whether changes are working.
Improvements rarely show up all at once. New pages first need to be crawled and indexed, then to start ranking for the searches ChatGPT runs. Third-party mentions take longer, since you depend on other sites publishing. Measure the same prompts weekly and look at the trend across several weeks rather than reacting to a single answer.
Blocking all OpenAI user agents because of training concerns, which also removes you from ChatGPT search.
Vague positioning. If your pages never say “X is a [category] tool for [audience]”, ChatGPT has nothing clear to quote.
Ignoring third-party sources. Recommendations usually reflect what independent pages say, not only your own site.
Outdated information on review sites and directories, which ChatGPT then repeats as fact.
Organic recommendations in ChatGPT answers can't be bought. OpenAI has introduced ads in some ChatGPT tiers, but they are labeled and separate from the answer itself.
Responses are generated, not retrieved, so wording and the brands named vary between runs, and search results change over time. That's why visibility should be measured as a rate across many runs, not from one screenshot.
OpenAI says ChatGPT search uses third-party search providers as well as its own crawler, and Bing is widely understood to be one of them. Being well indexed in Bing is a practical step toward appearing in ChatGPT answers.
For answers that use live search, new or updated pages can show up within days to a few weeks of being indexed. Changes that depend on the model's training data take much longer, because they only arrive with new model versions.
No. GPTBot collects training data, while ChatGPT search relies on OAI-SearchBot and live fetches by ChatGPT-User. You can block GPTBot and still appear in ChatGPT search answers, as long as the other two are allowed.
