What GEO does
  • your company is named for the question your customer asks
  • your page is the source that gets cited
  • with indexed, quotable, distinctive content, no tricks
Not just ChatGPT and GeminiOn every AI platform where your customers ask.

What is GEO?

Generative Engine Optimization: the work that makes AI platforms name your company as the answer when someone asks about your service. Not only in ChatGPT and Gemini: ChatGPT, Google AI Overviews and AI Mode, Gemini, Perplexity, Microsoft Copilot, Claude, Grok, Meta AI and DeepSeek.

There is no special trick to it. You need indexed, quotable content with a unique point of view that answers a question in one sentence and then goes into detail.

How does AI search work?

According to Google's documentation, AI Overviews and AI Mode split the question into several sub-queries (query fan-out) and assemble the answer from the page passages found for them. According to Semrush's April 2026 analysis, ChatGPT searches the web for 34.5 percent of queries.

This is why a page does not compete for one main keyword but for sub-questions: every H2 and H3 needs its own short answer.

What makes AI quote you?

Five things that make an AI platform choose your page as a source.

answer

A one-sentence answer at the top of the page, with a number or a concrete fact.

AI search looks for page passages that match the sub-questions. If the answer is in the first sentence, it can quote it.

own data

Measurements, cases, experience that cannot be found elsewhere.

AI does not repeat what appears the same way in a hundred places. It quotes what only you have.

structure

H1 is the question, H2 the sub-questions, a table for the numbers.

A clean structure makes the answer easy to pick out.

FAQ

Questions and answers in the customer's own words, one or two sentences each.

People search AI platforms with questions too, so these sections are easy to quote.

mentions

If other websites, videos and forums talk about you, AI trusts you more too.

According to the Ahrefs brand study, AI mentions correlate most strongly with mentions of the brand name on the web and on YouTube.

AI platforms and their sources

Which platform works from which source. The details change, so we measure regularly.

Do you need llms.txt?

Google Search does not use it, and it has no effect on visibility. The Google-Extended setting does not remove your site from AI Overviews and AI Mode either; it only affects Gemini training and grounding.

What is worth keeping in order: indexability, structured data, consistent company details everywhere, a fresh date on updated pages.

How much does GEO optimisation cost?

It depends on the number of questions and pages, as monthly work. After an assessment we give you an exact quote.
