What is GEO? Generative engine optimization, explained

4 min read

More of your buyers now ask an AI assistant a question and read the answer, instead of scrolling a page of links. The answer usually names a handful of sources. If your business is not one of them, you are invisible in that moment, even if you rank well on Google.

GEO is the work of fixing that.

What GEO means

GEO stands for generative engine optimization. It is the practice of making your brand and your pages easy for AI systems to find, understand, and cite when they generate an answer. "Generative engines" are tools like ChatGPT, Perplexity, Gemini, Claude, and Copilot, plus AI summaries inside search results such as Google's AI features.

The term was popularised by a research paper, GEO: Generative Engine Optimization, which tested how changes to a web page affect its visibility inside AI-written answers. If you want the wider picture of how GEO sits next to SEO and AEO, read SEO vs AEO vs GEO: what is the difference.

How AI assistants choose what to cite

Nobody outside the AI companies knows the exact rules, and they change often. But two broad mechanisms explain most of what you see:

  • Live retrieval. Many assistants search the web when you ask, read a few pages, and write an answer that links back to them. To be cited here, your page has to be reachable, easy to read, and a clear answer to the question.
  • What the model already knows. Assistants also lean on patterns from their training data. If your brand is mentioned consistently across trusted sites, it is more likely to be recognised and named.

So GEO has two jobs: be easy to retrieve today, and be well known across the web over time.

What actually moves the needle

None of this is magic. It is careful, repeatable work:

  1. Let the bots in. If your robots.txt or firewall blocks AI crawlers, nothing else matters. See how to let AI crawlers read your website.
  2. Answer the question first. Put a short, direct answer at the top of the page, then explain. Assistants and answer boxes both lift short passages that stand on their own.
  3. Back claims with sources. The GEO research paper reported that adding citations, quotations from relevant sources, and statistics improved visibility in generative answers in its tests. Results in the real world vary, but pages that show their evidence are easier to trust.
  4. Say clearly who you are. Use the same business name everywhere, describe what you do in plain words, and add structured data so machines can read the facts.
  5. Earn mentions elsewhere. Industry publications, directories, review sites, and communities are the places assistants already draw on. Being described accurately there helps.
  6. Keep the SEO basics strong. Google states that the same SEO best practices apply to its AI features. GEO does not replace SEO. It sits on top of it.

How to measure GEO

Traditional rankings do not tell you whether an AI assistant names you. A simple method works:

  1. Write 20 to 50 questions your buyers really ask.
  2. Run them across ChatGPT, Perplexity, Gemini, and Copilot.
  3. Record which brands and pages get cited, and whether you appear.
  4. Repeat every few weeks and compare.

Treat individual answers with care. Assistants can give different answers to the same prompt, so look for the trend across many prompts, not one lucky or unlucky reply.

What GEO cannot do

No honest agency can guarantee that a specific assistant will mention you. What an AI chooses to show is outside anyone's control. What you can control is the work: being crawlable, being clear, being sourced, and being present on the sites that matter. That is what we mean when we say we work towards getting you listed and report what happens.

Where to start this week

  • Open your robots.txt and check it does not block the AI crawlers you want.
  • Pick your five most important pages and add a short, direct answer at the top of each.
  • Write down 20 questions your buyers ask, and test them in two assistants.
