Generative Engine Optimization (GEO): how to get cited by AI

GEO is SEO for AI answers. Learn how ChatGPT, Claude, Perplexity and Google's AI Overviews decide what to cite — and the concrete steps to get your brand into the answer.

People increasingly ask an AI assistant instead of scrolling a page of blue links. If ChatGPT, Claude, Perplexity or Google's AI Overviews don't know you — or cite a competitor instead — you're invisible in the fastest-growing discovery channel. Generative Engine Optimization (GEO), sometimes called Answer Engine Optimization (AEO), is the practice of making your site easy for these systems to read, understand and quote.

Note: GEO doesn't replace SEO — it extends it. Most GEO wins (clean structure, entities, fast crawlable pages) also help classic search.

How AI systems choose what to cite#

There are two distinct pathways, and they need different things from you:

  • Training knowledge — what a model 'remembers' from its training data. You influence this over months through broad, reputable presence: mentions in press, Wikipedia/Wikidata, directories and other sites' content.
  • Retrieval / live fetch — when an AI search engine (Perplexity, ChatGPT search, AI Overviews) fetches pages at query time. This is where on-page GEO pays off immediately: the bot must be able to reach, render and extract your content.

You control the second pathway directly and seed the first over time. Both reward the same thing: clear, factual, well-structured, crawlable content.

Make your pages machine-readable#

  • Server-render your content. If it only appears after JavaScript runs, many AI fetchers see an empty shell. See the SSR-for-AI guide.
  • Use a clear heading hierarchy (one H1, logical H2/H3) and short, self-contained paragraphs. Models extract passages — a paragraph that answers a question on its own is far more quotable.
  • State facts explicitly. Put the key claim first ('X is a Y that does Z'), then elaborate. Front-load answers.
  • Add structured data (Organization, Article, FAQ, Product). It tells machines what your entities are. See adding JSON-LD.

Establish your entity#

AI systems reason about entities (a company, person, product), not just keywords. Help them connect the dots:

  • Publish an Organization JSON-LD with your name, logo, URL and sameAs links to your official social/Wikipedia/Crunchbase profiles.
  • Keep your name, description and category consistent across your site, social bios and directories — contradictions dilute recognition.
  • Earn third-party mentions. A Wikipedia page, reputable press and niche directories are strong recognition signals for training-time knowledge.

Let the AI crawlers in (on purpose)#

You can't be cited by a system you block. Decide access deliberately rather than by accident:

  • Check your robots.txt and CDN/WAF rules aren't silently blocking GPTBot, ClaudeBot, OAI-SearchBot, PerplexityBot and friends.
  • Confirm they actually visit by checking your access log with the AI Crawler Log Analyzer.
  • Publish an llms.txt to point AI systems at your most important pages.
Watch out: Blocking training crawlers (e.g. GPTBot) is a legitimate choice to keep your content out of datasets — but it can also reduce how well models 'know' you. Block training, allow AI search is a common balance.

Measure your AI visibility#

What gets measured gets improved. Ask the models directly what they know about you, and track whether it's accurate and current.

Our AI Visibility Checker queries a model about your brand, compares its answer to your live site, and gives you a score plus specific fixes.

Frequently asked questions

▸ What is the difference between SEO and GEO?

SEO optimizes for ranking in a list of search results. GEO (Generative Engine Optimization) optimizes for being understood and cited inside an AI-generated answer. They overlap heavily — clean structure, crawlability and authority help both — but GEO adds an emphasis on extractable facts, entity clarity and AI-crawler access.

▸ How long does GEO take to work?

On-page changes (server rendering, structured data, crawler access, llms.txt) affect live retrieval quickly — within a crawl cycle. Influencing a model's training knowledge is slower and takes months of broad, reputable presence.

▸ Do I need to block AI crawlers?

No — blocking is optional and mostly relevant if you don't want your content in training datasets. If you want to appear in AI answers, you generally want to allow AI search/retrieval crawlers.

▸ Is llms.txt required for GEO?

It's not required and not yet universally consumed, but it's low-cost, forward-looking, and a clear signal of your most important pages. It complements — never replaces — good HTML and structured data.
