What is Generative Engine Optimization?

In short

GEO turns your content into the source AI systems cite in their answers, and your company into the recommendation they make.

Generative Engine Optimization, or GEO, is the optimisation of websites and content for AI-powered search systems. These include ChatGPT with web search, Google AI Overviews and AI Mode, Perplexity, Gemini and Microsoft Copilot. Instead of a list of ten links, these systems return a finished answer with a handful of sources.

The term comes from a 2023 research paper by scientists at Princeton University and other institutions. They showed that targeted changes to the text, such as statistics, quotations and cited sources, can increase visibility in AI answers by up to 40 percent.

For businesses, this means ranking on page one is no longer enough. What matters is whether the AI reads your page, understands it, trusts it and puts your sentence into its answer.

GEO doesn’t replace SEO. It builds on it: what can’t be found can’t be cited.

Why now

Search is turning into answers

When people ask a question today, they increasingly get a finished answer. The list of links slides down, or disappears altogether.

10 links, the user clicks and compares

One answer, three sources. If you’re not in it, you don’t exist.

Answers, not lists

AI systems merge several sources into one answer. Only a few websites get named in it.

Fewer, but better clicks

People who arrive via an AI recommendation have often already compared and are closer to enquiring.

The recommendation decides

Questions like “Who is good for …?” get answered with names. That’s exactly where you want to be.

Behind the scenes

How AI systems choose their sources

An AI rarely answers a question with a single search. It splits the question, finds matching passages for each part and assembles the answer from them. Google calls this “query fan-out”.

Question

“Which installer in Wiesbaden fits heat pumps in older houses?”

  • What does it cost?
  • Who offers it near me?
  • How do I spot quality?
  • What do others say?
  • How does it work?
Answer

Assembled from the passages that answer each sub-question most clearly.

1

Split

The question is broken into several searches, often five to ten.

2

Retrieve

Pages are fetched from a search index for each sub-question; for Google, from the Google index.

3

Select

From these pages, the passages that are clear, backed up and trustworthy are chosen.

4

Answer

The AI writes the answer and links some of the sources it used.

The winner isn’t the longest page, it’s the clearest passage for the right sub-question.
What works

The 7 levers for visibility in AI answers

We check these seven points in every GEO audit. The order follows the path a query takes through an AI system: from text to technology to brand.

01

Quotable passages

AI systems lift individual passages, not whole pages. So the first sentence under every subheading answers the question completely, with no preamble and no “as mentioned above”.

Answer first, reasoning after

02

Facts, figures, your own data

Concrete values beat adjectives. Project durations, price ranges, experience and cited sources make a claim verifiable and therefore worth quoting. Your own figures are something nobody else has.

Add statistics and sources

03

Cover the follow-up questions

An AI splits one question into several sub-questions and looks for a source for each. Pages that answer cost, process, alternatives and typical objections in one place get used more often.

Topic clusters, not lone pages

04

Technology AI can read

Content has to be in the HTML without JavaScript, load fast and be open to the right crawlers. Structured data (Organization, Person, Service, FAQ) tells machines who offers what.

robots.txt, schema, server rendering

05

Brand and entity

For recommendations, what counts is how often and in which context your name appears elsewhere: industry portals, reviews, press, associations, your Google Business Profile. Consistent details everywhere make you unambiguous to AI.

Mentions where AI looks

06

Make expertise visible

Who wrote this, and why should anyone trust them? Real authors with a profile, practical examples, references and a clear legal notice are the trust signals that search engines and language models both evaluate.

Author profile, references, proof

07

Measure, don’t hope

We define the questions where your company should be named and check regularly whether that happens and with which statement. Visits from ChatGPT, Perplexity and others in GA4 come on top.

Mention rate per prompt

How visible is your company in ChatGPT?

We check it in the intro call using your three most important customer questions. Free and without obligation.

In 2 minutes

GEO self-check: how ready is your website?

Eight questions, answered honestly. The result shows where your biggest levers are. Nothing is stored or sent.

  1. Does the first sentence under each subheading answer the question directly?

  2. Do your key pages state concrete figures (prices, duration, experience)?

  3. Is there a real, named author with a profile behind your content?

  4. Are your name, address and phone number identical everywhere online?

  5. Does your robots.txt allow search and AI search crawlers?

  6. Does your website have structured data for company, services and FAQ?

  7. Are you mentioned on portals, in the press or by associations in your industry?

  8. Do you know whether ChatGPT names your company for your core topics?

Services

What we do for your AI visibility

Six building blocks we combine depending on where you start. You don’t get theory, you get implemented changes to your website and profiles.

Audit

AI visibility audit

We ask ChatGPT, Google AI Overviews, AI Mode, Perplexity and Gemini 30 to 50 questions your customers ask. Result: where you get named, where competitors do, and which sources the AI relies on.

Content

Make content quotable

Service pages and guides get a clear answer structure, verifiable figures and the follow-up questions that are missing today. We rewrite where needed and revise where the content already works.

Tech

Technology and structured data

Crawler access, server rendering, load time, schema.org for organisation, person, services and FAQ. Plus your Google Business Profile and, where useful, an llms.txt.

Brand

Mentions and profiles

We find the portals, directories and media that AI systems cite for your topics, and make sure you are listed there correctly and completely.

Monitoring

Monitoring and reporting

Every month the same prompts, the same systems: mention rate, statement, competitor comparison and AI visits in GA4. You see what moves, and we adjust.

Combined

GEO with SEO and Google Ads

GEO builds on SEO and doesn’t replace advertising. Because we look after all three, content, technology and campaigns work together instead of side by side.

Process

Four steps to AI visibility

1

Intro call

30 minutes on video. We clarify goals, topics and competitors. Free of charge.

2

Audit

Prompt set, status in five AI systems, tech check, source map.

3

Implementation

Content, schema, crawler access and profiles, ordered by impact.

4

Monitoring

Monthly report with mention rate, competitor comparison and next steps.

Measurable

How we measure AI visibility

Ranking tools don’t show what ChatGPT says about you. That’s why we work with a fixed prompt set: 30 to 50 questions your customers actually ask, sorted by purchase intent.

Every month we ask these questions in the same systems and record whether you are named, with which statement and next to which competitors. In GA4 we separate visits from ChatGPT, Perplexity, Gemini and Copilot cleanly from other traffic.

  • StatementWhat the AI says about you, and whether it’s right

Straight talk

GEO myths and what’s actually true

There are lots of promises around AI search. These are the five we hear most.

“GEO replaces SEO.”

Fact

No. AI Overviews and AI Mode draw on Google’s index, ChatGPT and Perplexity on their own and third-party search indexes. If you can’t be found, you can’t be cited. GEO builds on SEO.

“An llms.txt is enough.”

Fact

llms.txt is a proposal from 2024. No major provider has confirmed that it uses the file for answers so far. It costs little, but it doesn’t replace good content.

“Google-Extended keeps me out of AI Overviews.”

Fact

No. Google-Extended controls use for Gemini models. AI Overviews use the regular Googlebot. Opting out there means restricting snippets, which also costs classic visibility.

“Lots of AI-written text brings lots of AI citations.”

Fact

Interchangeable mass content offers nothing a language model doesn’t already know. What gets cited is new, concrete and backed up: your experience, your figures, your examples.

“Hidden instructions to the AI help.”

Fact

Hidden text and prompt tricks violate search engine guidelines, get detected and damage trust in your brand. We only use clean methods.

FAQ

Frequently asked questions about GEO

What is Generative Engine Optimization (GEO)?

GEO means preparing content and your website so that AI systems such as ChatGPT, Google AI Overviews, AI Mode, Perplexity and Gemini use them in their answers and name your company as a source or recommendation.

What is the difference between GEO and SEO?

SEO aims for a good position in the results list, GEO for becoming part of the answer. In SEO, pages compete for a click; in GEO, passages compete for a citation. GEO builds on SEO.

Who is GEO worth it for?

For anyone whose customers research before buying: practices, trades, online shops, B2B providers and service businesses. Especially when customers ask for recommendations (“Who is good for …?”).

How quickly do you see results?

Search systems with AI features often pick up technical fixes and new content within a few weeks. Mentions on other sites and model knowledge take longer. We measure monthly and show the trend.

Can you guarantee that ChatGPT names my company?

No, and nobody can honestly do so. AI answers vary with the question, location and history. We can raise the likelihood significantly and make progress measurable with fixed prompts.

Should I block AI crawlers in robots.txt?

It depends on your goal. Blocking search crawlers such as OAI-SearchBot (ChatGPT search) or PerplexityBot prevents citations. Training crawlers such as GPTBot can be allowed or blocked separately. We review your settings and recommend a clear rule.

How do you measure AI visibility?

With a fixed set of questions asked regularly across several AI systems. We measure mention rate, what is said about your company, cited sources and competitors. Plus AI visits in GA4.

Do I need a new website for this?

Usually not. In most cases targeted changes to the content, structure and technology of existing pages are enough. A relaunch only pays off if the technology doesn’t deliver content in a readable form.
