To be recommended in ChatGPT: (1) don’t block OAI-SearchBot in robots.txt — OpenAI states that sites opted out of it are not shown in ChatGPT search answers[1]; (2) write pages in Q&A form, readable without JavaScript; (3) keep brand details consistent everywhere; (4) earn verifiable mentions in the list articles, directories and trade media ChatGPT often cites; (5) measure monthly with a fixed question set.
Where does ChatGPT pick its sources?
When a question needs fresh information, a local recommendation or a comparison, ChatGPT searches and synthesizes an answer from the pages it finds[2] — your site has to be crawled and indexed by then. Without search, the model relies on what it saw about your brand in training data. So your brand must be findable on the web today and described consistently across the web over time.
| Crawler | What it does | If you block it |
|---|---|---|
OAI-SearchBot | Crawls sites to surface in ChatGPT search results | You are not shown in ChatGPT search answers |
GPTBot | Collects content for training future models | Your content isn’t used for training; no direct effect on search visibility |
ChatGPT-User | Visits a page when a user asks ChatGPT to open it | User-initiated, so robots.txt rules may not apply |
7 steps to appear in ChatGPT
- Verify bot access: keep
OAI-SearchBotallowed in robots.txt. The GEO Readiness Check tests this in seconds. - Put content in HTML: pricing, scope, address and FAQs as plain text on the page — not inside images or JavaScript.
- Write question → answer: the sentence your customer would type into ChatGPT becomes the H2, the answer comes first (citable content).
- Define your entity: Organization/LocalBusiness schema, consistent name-address-phone, official profiles via
sameAs(entity SEO). - Don’t ignore Bing: Bing Webmaster Tools verification and IndexNow; Bing’s index is widely understood to be part of the search ecosystem ChatGPT draws on.
- Earn third-party mentions: “Best … 2026” list articles, industry directories, news sites and comparison content are frequently cited in ChatGPT answers.
- Measure: ask the same question set monthly in a clean session with search on, and archive the answers (measurement guide).
How do you check whether your brand shows up in ChatGPT?
- Use a temporary chat (no history, no memory) and ask in your customer’s words: “Which clinic would you recommend for implants in Istanbul?”
- Repeat the same question at least three times on different days — one answer can be chance.
- Note the source links under the answer: your page, a list article or a competitor?
- Track
chatgpt.comsessions in GA4 (GA4 guide).
