AI SEO — get found when customers ask an AI

What AI SEO is — the definition

AI SEO is the work of making your business visible and citable in AI search: the answers that AI assistants and AI-powered search engines give when a customer asks a question. Where classic SEO is about ranking in Google's blue links, AI SEO is about being part of the AI answer itself.

The shift is fast: more and more people start their research in ChatGPT or Perplexity, and Google increasingly shows an AI-generated answer at the top — above the blue links. AI SEO is the response to that shift.

"AI SEO" is a broad, practical term. The two precise disciplines behind it are GEO and AEO — which we cover below. You will also see the same field called AIO (AI Optimization) and LLM SEO.

AI SEO, GEO and AEO — how they connect

They connect directly. AI SEO is the umbrella; GEO and AEO are the two disciplines under it. Each optimises for a different surface, but the work overlaps heavily:

GEO is the academically established term (formalised in Princeton/Georgia Tech research, KDD '24) for optimising toward generative engines; AEO is used more broadly for all answer surfaces. When someone searches for "AI SEO", they mean a combination of the two in practice.

AI SEO vs. classic SEO — does it replace your SEO?

No — AI SEO does not replace SEO; it builds on it. Much of the foundation is shared: a technically sound site, crawlable content, clear structure and credibility. But the goal moves: from ranking in a list to being part of the answer.

The key difference is what gets rewarded. Classic SEO often rewards domain authority and links. AI SEO rewards citability: precise, well-structured answers, an unambiguous brand entity and machine-readable data. That is why a small, sharp business can win AI visibility even against larger competitors — most have not started yet.

What AI SEO asks of your content

AI search engines reward content that is easy to understand, extract and trust. The most important signals:

• Answer one question directly and early. Put the short, concrete answer in the first couple of sentences — that is the block AI models lift out.
• Structure with questions as headings. H2s phrased as the questions customers actually ask.
• Use lists, tables and short paragraphs. Structured content is extracted more easily than long walls of text.
• Add structured data (schema). FAQPage, HowTo and Organization make the answer machine-readable.
• Make sure AI can read the page. If your page needs JavaScript to show content, AI crawlers see an empty shell — check it with the AI Readability Check.
• Publish an llms.txt. The file gives AI a curated overview of your business — create one for free with the llms.txt generator.

These are the same signals the GEO test measures — so your AI SEO effort is one combined effort.

Getting started with AI SEO

1. Measure your starting point. Run the free GEO test (60 seconds, no login) and see which signals keep you out of the AI answers.
2. Make sure AI can read your page. Check robots.txt and JavaScript dependence with the AI Readability Check.
3. Make the content answer-friendly. Answer concrete questions directly, with question headings and short paragraphs.
4. Add structured data and an llms.txt. Use the llms.txt generator and add FAQPage schema.
5. Measure again, and repeat. AI visibility is built over time — track your GEO Score and fix what drags it down.

If you want it done automatically, the Geoa platform measures and fixes these signals for you via the WordPress or Shopify integration — from DKK 299/month with a 14-day free trial, no card required. See the full picture in the complete GEO guide.

Frequently asked questions about AI SEO

Is AI SEO the same as GEO?

Almost. AI SEO is the broad, everyday label; GEO (Generative Engine Optimization) is the precise term for being cited in generative AI answers. When people say "AI SEO", they usually mean GEO plus AEO.

Does AI SEO replace my regular SEO?

No. AI SEO builds on top of SEO. The foundation — a technically sound, crawlable site — is shared. But the goal shifts from ranking in a list to being part of the AI answer itself, and it rewards citability over raw domain authority.

Can I measure my AI SEO for free?

Yes. Run the free GEO test (60 seconds, no login). It scores the technical signals that decide whether AI can find, understand and cite you.

Which AI search engines does AI SEO apply to?

The main ones are ChatGPT, Perplexity, Claude and Gemini, plus Google's AI Overviews. The work is largely the same across them: make your content easy to understand, extract and cite.

Can a small business win at AI SEO?

Yes — often more easily than a large one. AI answers reward precise, well-structured content over sheer domain size, and most small and medium-sized businesses have not started yet. You can get far with the free tools.

Is AIO (AI Optimization) the same as AI SEO?

In practice, yes — AIO (AI Optimization) is another name for making your business visible in AI search, like AI SEO, LLM SEO and the precise term GEO. Note, though: "AI optimization" is also used broadly for optimising the AI models themselves — so context decides the meaning.
