How to Rank in ChatGPT

SEO for ChatGPT: how it differs from Google SEO

SEO for ChatGPT - sometimes called ChatGPT SEO - rests on the same foundations as Google SEO but optimises for a different outcome. Google SEO competes for a ranked link someone clicks; ChatGPT SEO competes for a citation inside a generated answer. The overlap is large - crawlable pages, clean structure, schema and real authority help both. The difference is the extra layer ChatGPT depends on: crawler permissions for OpenAI’s bots, unambiguous entity signals, and answer-first content it can lift verbatim. Treat it as Google SEO plus that layer, not a separate discipline - the four steps below are that layer, in order.

1. Let ChatGPT's crawlers in

OpenAI uses three crawlers: OAI-SearchBot (powers ChatGPT Search), ChatGPT-User (fetches pages when a user asks) and GPTBot(training). A blanket Disallow in robots.txt - often copied from an old template - makes you invisible to all of them, and it’s the single most common reason a site never gets cited. Set your rules deliberately with the free robots.txt generator.

2. Give it something quotable

• Lead each page and section with a direct answer, then expand - ChatGPT lifts the first clear sentence that answers the question.
• Phrase headings as the questions people actually ask it.
• Add FAQ structured data for genuine questions, and Organization schema so it knows who's answering.
• Keep facts unambiguous: one business name, one description, one location, everywhere.
• Publish an llms.txt summarising your site - build one in a minute with the free llms.txt generator.

The llms.txt generator and schema validator cover the two mechanical steps here.

3. Become an entity it trusts

ChatGPT is far more likely to cite brands that exist in the knowledge sources it leans on - Wikipedia, Wikidata and established industry sites. You can’t shortcut this, but you can compound it: consistent NAP details, real authorship, and coverage on sites AI already trusts. This is the slow layer - start it now, because it’s the moat.

4. Measure it - don't guess

“Are we visible to ChatGPT?” is checkable in seconds: the AI Visibility Checker verifies per-engine crawler access (ChatGPT, Claude, Perplexity, Gemini and more) and whether you exist in Wikipedia and Wikidata - then tells you exactly what’s holding you back. For the broader picture, run a free GEO audit, see how the same work plays out in Perplexity and Google’s AI Overviews, or read the umbrella guide to AI search optimisation.
