Quick answer
Generative engine optimization (GEO) is the practice of making your content easy for AI answer engines to find, trust, and cite. It builds on SEO: pages must be crawlable and indexed, then written answer-first with clear facts, specific details, and named sources. Consistent brand information across the web helps AI systems describe your business correctly.
- GEO is an extension of SEO, not a replacement for it.
- Google says there are no special requirements for its AI features beyond SEO best practices.
- AI crawlers must be allowed, and content must be in the HTML.
- Specific, verifiable facts are easier to quote than general claims.
What is generative engine optimization?
The term comes from a 2023 research paper, "GEO: Generative Engine Optimization", which studied how content changes affect visibility in AI-generated answers. It found that adding things like citations, quotations, and statistics from credible sources tended to improve visibility. Answer engine optimization (AEO) is a closely related term focused on direct answers.
In practice, GEO asks: when someone asks an AI assistant about your category, does it know your brand, describe it correctly, and link to your pages?
How do AI answer engines choose sources?
- Google AI Overviews and AI Mode
- Draw on pages in the Google index. Google says a page must be indexed and eligible to show a snippet to be used, and that no extra optimisation is required beyond SEO best practices.
- ChatGPT search
- Uses its own crawler, OAI-SearchBot, to find pages to show in search results. OpenAI documents a separate crawler, GPTBot, for model training.
- Perplexity
- Crawls with PerplexityBot and cites sources inline.
- Microsoft Copilot
- Builds on the Bing index, so Bing Webmaster Tools and IndexNow help.
Check each provider's documentation before changing robots.txt, because blocking a crawler can remove you from its answers.
How do you optimise content for AI answers?
- Make it crawlable. Allow search and AI crawlers in robots.txt and put main content in the HTML, not only in JavaScript.
- Answer first. Open each page with a direct 40 to 60 word answer to the main question.
- Use question-led headings. Match the way people ask: what, how, how much, which, versus.
- Be specific. Steps, timelines, criteria, and named sources instead of vague claims.
- Show who you are. Author or brand byline, about page, contact details, and real proof.
- Add structured data. Organization, Article, FAQPage, Product, or LocalBusiness that matches visible content.
- Keep brand facts consistent. Same name, description, and details on your site, profiles, and directories.
- Earn mentions. Coverage and citations from trusted industry and local sources.
How do you measure GEO?
- Referral traffic from AI assistants in your analytics, such as chatgpt.com and perplexity.ai
- Search Console data, which includes AI Overviews and AI Mode traffic within Web search
- A fixed list of prompts tested regularly to see whether and how your brand appears
- Branded search volume and direct enquiries that mention AI tools
What are common GEO myths?
- You need a special AI file to be cited. llms.txt is a proposal, not an official standard of the major search engines. It does no harm, but it is not a substitute for crawlable content.
- GEO replaces SEO. AI engines rely on the same crawled, indexed web.
- Keyword stuffing for AI works. Clear, specific, helpful content works better.
- Anyone can guarantee AI citations. No one controls how AI systems answer.

Frequently asked questions
What does GEO stand for in marketing?
Generative engine optimization: improving how often and how accurately AI answer engines cite your content and brand.
Is GEO different from SEO?
GEO builds on SEO. Crawlability, indexing, and helpful content are the foundation; GEO adds answer-first structure, specific facts, and brand consistency for AI answers.
How do I get my business mentioned by ChatGPT?
Allow OAI-SearchBot, publish clear and specific pages about your products and services, keep brand facts consistent across the web, and earn mentions on trusted sites.
How do I appear in Google AI Overviews?
Follow SEO best practices so your pages are indexed and eligible for snippets, and answer questions clearly. Google says no special optimisation is needed.
Should I block AI crawlers?
If you want to be cited in AI answers, allow the search crawlers of those services. Some providers use separate crawlers for training, which you can decide on separately.
Does llms.txt help with AI search?
It is a community proposal, not an official standard of the major search engines. It is low effort to add but does not replace crawlable, well-structured pages.
How long does GEO take to work?
Like SEO, it depends on how often engines recrawl your pages and how competitive the topic is. Track a fixed set of prompts over months.
