How to Get Your Brand Discovered by ChatGPT and Other LLMs

You do not “rank in ChatGPT” the same way you rank in classic web search. For ChatGPT and other LLMs, your site tends to show up more when it is crawlable, easy to understand, credible, specific enough to quote, fresh enough to trust, and already strong in normal search. The practical goal is not generic “SEO for robots”—it is becoming the best source for a narrow set of questions your buyers actually ask.

OpenAI: search vs training crawlers

OpenAI’s Overview of OpenAI Crawlers documents separate controls: OAI-SearchBot is used to surface sites in ChatGPT search features; sites that opt out are not shown in ChatGPT search answers (navigational links may still appear). GPTBot may crawl content for foundation model training. The two settings are independent—you can allow search inclusion while disallowing training, or the reverse. OpenAI notes that robots.txt updates can take on the order of 24 hours to affect search behavior.

Google: AI Overviews and AI Mode

Google’s AI features and your website states that to be eligible as a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to be shown in Google Search with a snippet—there are no additional technical requirements. The same SEO fundamentals apply (crawlable robots.txt, helpful people-first content, textual content, structured data that matches visible text). Google explicitly says you do not need new machine-readable AI files or special schema.org markup just for these features.

Microsoft: IndexNow and AI Performance

IndexNow (Bing) is an open protocol for notifying search engines when URLs are added, updated, or removed. Microsoft’s AI Performance in Bing Webmaster Tools surfaces how often your content is cited in generative answers across experiences such as Copilot and Bing; the same post ties fresh content to better inclusion and points publishers to IndexNow.

A. Fix technical access first

• Allow OAI-SearchBot in robots.txt if you want ChatGPT search visibility; review GPTBot separately (training vs search).
• Avoid accidental noindex on important URLs; return clean 200 responses and fast HTML.
• Ship XML sitemaps; verify the site in Google Search Console and Bing Webmaster Tools.
• Use IndexNow when you publish or change important pages—especially if content changes often.

Example pattern (only if you want those crawlers to access the whole site): User-agent: OAI-SearchBot / Allow: /, User-agent: GPTBot / Allow: /, plus your Sitemap directive. OpenAI treats these controls independently—choose deliberately.

B. Write pages that are easy to cite

• Put the exact question in the title; answer directly in the first paragraph.
• Add short summary bullets, then detail, examples, and definitions.
• Show authorship or company ownership; add a last-updated date when facts change.
• Link to specs, pricing, policies, and deeper docs—thin marketing copy is a weak citation source.

C. Standard structured data (not “AI-only” markup)

You do not need special LLM-only schema for Google’s AI features, but standard JSON-LD (Organization, Product, Article, FAQPage where honest, BreadcrumbList) helps search engines understand entities and can reduce ambiguity. Whatever you add must match visible content.

D. Build entity trust

• Keep brand and product naming consistent; use sameAs for official profiles.
• Keep pricing, docs, privacy, terms, and contact pages public and easy to find.
• Publish concrete facts that would otherwise live only in sales calls or gated PDFs.

E. Measure and iterate

• Use Search Console and Bing Webmaster Tools; review Bing AI Performance for citation-oriented signals where available.
• Manually test how ChatGPT, Copilot, Gemini, and Perplexity answer questions in your category and note which URLs get cited—improve those pages first.

• ChatGPT-User: OpenAI documents a separate user agent for user-initiated browsing from ChatGPT. It is not the same as automatic crawlers; do not assume one robots.txt line controls every retrieval mode.
• Guarantees: Google is explicit that meeting technical requirements does not guarantee appearance in AI surfaces—quality and relevance still decide what gets shown.
• Schema: Standard structured data helps understanding; it is not a citation guarantee by itself—pair it with clear, specific answers.
• llms.txt: Treat as optional/experimental. There is no broad requirement from Google or OpenAI comparable to documented crawler controls in robots.txt.

Technical

• Confirm OAI-SearchBot is not blocked if you want ChatGPT search inclusion.
• Review GPTBot separately; remove accidental noindex; verify sitemap health.
• Verify Search Console and Bing Webmaster Tools; enable IndexNow if you ship frequent updates.

Content

• Build pages around exact buyer questions; answer first, detail second.
• Keep key facts public; add update dates; avoid scaled filler without added value.

Trust

• Consistent naming; public policies and pricing; Organization schema on the homepage where appropriate.

Most of “LLM SEO” is strong technical SEO plus excellent documentation and brand clarity. What is relatively new is that users ask longer, narrower questions, models favor pages that can be quoted safely, and entity clarity matters more than keyword stuffing. The winning move is usually fewer pages, clearer answers, and measurable iteration.

The public marketing site at citationworks.com serves robots.txt with User-agent: * and Allow: /, plus a sitemap URL. That pattern does not block OpenAI’s OAI-SearchBot or GPTBot by name. In production, still verify CDN or WAF rules, accidental noindex on key URLs, and sitemap freshness—edge configuration can override good defaults.
