What Is GEO? How to Get Your Business Cited by ChatGPT and Google AI Search

When a customer asks "can you recommend a good supplier in Adana?", the answer no longer always comes from ten blue links. ChatGPT, Gemini, Perplexity and Google's AI overviews read the question and compose an answer in their own words. If your name appears in that answer, you have won; if it does not, your ranking position matters very little in practice.

GEO, generative engine optimization, is the work of making your site readable and quotable by these answer engines. It does not replace SEO; it sits on top of it. The technical foundation is the same, but the measure of success is different: not ranking, but being cited.

Where do AI assistants get their answers?

Broadly, from two sources:

• Training data: the large archive of text a model read in the past. This knowledge is frozen at a certain date.
• Live web search: when a question needs current information, the assistant searches the web, reads the pages it finds and builds its answer from them.

The real opportunity for your business is the second one. Google's AI Overviews also draw on pages Google has already indexed, so a site that is invisible or technically broken on Google will struggle to appear in AI answers too.

The most common mistake first

Many sites block AI crawlers without realising it. A single line in robots.txt can mean your site never appears in ChatGPT's answers. These crawlers fall into two groups, and it is important not to confuse them:

• Answering crawlers (OAI-SearchBot, ChatGPT-User, Claude-User, PerplexityBot): they read your site at the moment a user asks something and cite it as a source. If you want visibility, these must be allowed.
• Training crawlers (GPTBot, ClaudeBot, Google-Extended, CCBot): they collect your content to train models. Blocking these is a legitimate choice and does not directly affect your visibility.

Open your own robots.txt and look. Which crawlers sit under a "Disallow: /" line? If you do not know the answer, chances are a plugin wrote that file.

What do answer engines quote?

When a language model reads your page it is looking for one thing: a self-contained passage that directly answers a question. Marketing sentences are poor candidates, because they say nothing once removed from their context. "We are the industry leader" does not get quoted; "delivery time for a corporate site depends on scope; a five-page brochure site usually takes three to four weeks" does.

The most practical consequence: break your content up with question-shaped headings. If a heading is a question and the paragraph directly under it answers that question, you have made the model's job easy. That is why an FAQ section is not decoration; it is infrastructure.

The layer machines read

Your page also has a version the human eye never sees. Search engines and answer engines learn from this layer what your business is, where you are and which questions you answer:

• Structured data (JSON-LD): business type, address, services, frequently asked questions. A definition that leaves nothing to interpretation.
• Sitemap (sitemap.xml): which pages exist. Without it, new pages go undiscovered for a long time.
• llms.txt: a newer file that hands over a plain-text map of the site. It is not yet an established standard used by all major AI companies; adding one does no harm, but do not expect it to be decisive on its own.
• Canonical URL: which address counts when the same content appears at several.

On sites where content only appears after JavaScript runs in the browser, some crawlers cannot read the page fully. Having important content directly in the page source is safer for both search and AI.

What happens off your site counts too

When an AI recommends a business, it does not only look at that business's own website:

• Consistent business information: your name, address, phone and description should match exactly across your website, Google Business Profile, LinkedIn and social profiles. Inconsistent information undermines trust.
• Others mentioning you: reviews, industry sites, news and directories all matter. What others say about you carries more weight than what you say about yourself.

Can any of this be measured?

Partly. Your site's technical readiness is fully measurable: a file is either there or it is not, a crawler either can read it or cannot. You can see all of that in minutes with our free Site Audit.

The outcome itself is harder to measure, but there are ways to track it:

1. 1The generative AI features report in Google Search Console shows how often your site appears in Google's AI features.
2. 2Regularly ask ChatGPT, Gemini and Perplexity the questions your customers would ask, and record whether you are mentioned and whether the facts are right.
3. 3Track visits from sources such as chatgpt.com and perplexity.ai in your analytics.
4. 4Ask new customers how they found you.

We applied it to ourselves

We applied every check described here to our own site. You can see the work we claim to do on ourselves: our robots.txt, llms.txt and structured data are all open. About two weeks after launch, our site started appearing in Search Console's generative AI features report.

Frequently asked questions

Is GEO only for large companies?

No. It is actually a big opportunity for local and niche businesses. When an AI wants to recommend a specialist in a certain city or field, a small company with clear, reliable information can stand out.

How long until results show?

Like SEO, it takes time. After changes, it can take anywhere from a few weeks to a few months for your site to be indexed and for AI systems to start using the information.

What if an AI gives wrong information about my business?

Find the source first; it is often an old directory listing, an outdated profile or a vague statement on your own site. State the correct facts clearly on your website and update your other listings.

Do I need to rebuild my current site?

Usually not. Making content more question-focused, adding structured data and fixing crawler permissions is typically a good enough start.
