What is GEO (generative engine optimization) and does your business need it?

GEO explained: how AI answer systems find and cite sources, what is the same as SEO and what you can do without hype.

Key takeaways

  • GEO (generative engine optimization) is the work of making your content easy for AI answer systems to find, understand and cite.
  • Most of it overlaps with good SEO: crawlable pages, clear structure, accurate facts and real authority.
  • No one can guarantee that an AI system will mention your business, so be sceptical of guarantees.

What GEO means

People increasingly ask questions to AI assistants and AI-powered search features, such as ChatGPT Search, Google AI Overviews and AI Mode, Gemini and Microsoft Copilot. These systems often retrieve web pages and summarise them, sometimes showing links to the sources. GEO is the practice of making your pages good candidates to be retrieved, understood and cited.

What is the same as SEO

  • Access: pages must be crawlable and not blocked by robots rules or login walls.
  • Quality: clear, accurate, helpful content that answers real questions.
  • Trust: consistent business details, real authors, reviews and mentions elsewhere.
  • Speed and structure: technically healthy pages with good headings.

What is different

AI systems tend to extract short passages. Pages that state answers directly, define terms, use tables and lists for comparisons, and include a clear FAQ are easier to quote accurately. Entity clarity matters too: it should be unmistakable who you are, where you operate and what you do. Structured data can help express this, as long as it matches visible content.

Practical steps

  1. Check crawl access for search and AI crawlers you wish to allow, using robots.txt and server settings.
  2. Write answer-first pages with a short summary at the top and details below.
  3. Keep facts consistent across your website, Google Business Profile and directories.
  4. Add structured data for your organisation, services, articles and FAQs.
  5. Earn mentions from reputable sites and customer reviews.
  6. Test regularly by asking AI tools questions your customers would ask, and note what they cite.

Measurement is imperfect

AI answers vary by user, location and time, and not every system reports its sources the same way. Treat any single result as a sample, repeat tests, and record what could not be measured. That honesty is central to the Smartise AI Visibility Audit.

What about llms.txt?

Some sites publish an llms.txt file as a human-readable guide to their key pages. It may help some tools, but support is not universal and it is not a ranking switch. Do not rely on it in place of good content.

Where to go next

Frequently asked questions

No. Traditional search remains important, and the fundamentals of GEO and SEO largely overlap.

Inclusion in organic AI answers is not something you can buy directly. Some platforms offer separate advertising products, which are labelled.

It is a business decision. Blocking can reduce the chance of being cited, while allowing may expose content to training or summarising. Review each crawler’s documentation and decide deliberately.
