What is GEO (Generative Engine Optimisation)?

GEO is structuring your website so AI tools like ChatGPT, Perplexity and Google AI Overviews recommend your business. Here's what it is and why it now matters.

Quick answer

GEO (Generative Engine Optimisation) means structuring your website's content, facts and code so AI answer engines like ChatGPT, Perplexity, Gemini and Google AI Overviews cite and recommend your business when people ask them questions. It is the AI-era version of SEO: you optimise to be the answer, not just to rank in a list of links.

Sixty percent of Google searches now end without a single click to anyone’s website. People get their answer on the results page, or straight from an AI, and never visit a site at all. That one number is the whole reason GEO exists.

GEO (Generative Engine Optimisation) is the practice of structuring your website so AI answer engines, ChatGPT, Perplexity, Gemini and Google’s AI Overviews, cite and recommend your business when someone asks them a question. SEO was about ranking you in a list. GEO is about making you the answer.

Why this is suddenly a thing

For twenty years the job was simple: get to the top of Google’s results. That worked because people scrolled a list of links and clicked one. They mostly don’t anymore.

Three things changed at once:

  • People now ask AI a question in plain English and read the one answer it writes back.
  • Google bolted its own AI Overview on top of the results, pushing the real links down the page.
  • Most searches get answered before anyone clicks anything.

So “page one of Google” is worth less than it was. What’s worth more is being the business the AI trusts enough to name. That’s a different game, and almost nobody in your local market is playing it yet.

How it differs from SEO

They’re cousins, not opposites. Good basics help both. But the emphasis moves.

SEO still matters, to be clear. Billions of people still click links every day. GEO is the second front door, not a replacement for the first.

What actually moves the needle

Here’s the good part: you don’t need backlinks or a budget to start. GEO rewards clarity, and a focused small business can be clearer than a sprawling competitor.

The biggest single win, the one I’d do before anything else, is to answer the customer’s question in the very first sentence of the page, in plain words, with a real fact in it. AI engines lift sentences that stand on their own. A vague intro gives them nothing to quote.

After that:

  1. Let the AI crawlers in. Your robots.txt should explicitly allow GPTBot, ClaudeBot, PerplexityBot and Google-Extended. Block them and you can’t be cited, full stop.
  2. State hard facts. “Live in 3 to 5 working days” gets quoted. “Fast turnaround” gets ignored.
  3. Add structured data (FAQPage, Article, Organization schema) so engines know what your page means.
  4. Publish a llms.txt file pointing AI at your best pages.
  5. Show a visible “updated” date. Engines favour content that looks current.

Test it in two minutes

Open ChatGPT or Perplexity right now and ask “who does [your service] in [your town]?” If your business isn’t named, that’s your GEO gap, and the list above is how you close it. Check again monthly to track progress.

The honest bit

GEO is early. The tactics will shift as the AI tools change, and anyone promising guaranteed citations is guessing. But the underlying bet is safe: more people will ask AI, fewer will scroll links, and the businesses that are clear, factual and easy to quote will get named. The ones hiding behind marketing fluff won’t.

Key takeaway

GEO is SEO for the age of AI assistants. Optimise to be quoted in the answer, not just ranked in the list, and start by answering the customer’s question in your first sentence with a real fact in it.

If you’d rather not wire up robots.txt, schema and llms.txt yourself, that’s exactly the sort of thing we handle as part of a managed online presence. Either way, the move is the same: make your business the easiest one for an AI to recommend.

Frequently asked questions

Is GEO different from SEO?

Yes. SEO gets you into the list of blue links on a results page. GEO gets you named inside the single answer an AI writes back. The foundations overlap, clean structure and good content help both, but GEO leans much harder on self-contained facts, plain definitions, structured data, and being a source worth quoting.

Do I need GEO if I already do SEO?

More and more, yes. A growing share of people ask ChatGPT or Perplexity instead of Googling, and Google now puts an AI Overview above the normal results. If you only live in the old blue links, you are invisible in the answer most people now read first.

How do I know if GEO is working?

Ask the AI tools yourself. Type the questions a customer would ask, like 'best [your service] in [your town]', into ChatGPT, Perplexity and Google's AI Overview, and see if your business gets named. Check again every month and you have a simple scorecard.
