What is GEO? How your business shows up in ChatGPT, Perplexity and Google answers
In short: GEO (generative engine optimization) means making your content a source that ChatGPT, Perplexity and Google’s AI summaries quote. Google says there are no additional requirements to appear in AI Overviews: the page needs to be indexed and eligible to show with a snippet, and standard SEO applies. The academic paper that coined the term found that optimising content can raise visibility in answers by up to 40%. Start with direct answers, numbers with sources, FAQs, structured data that matches the page, and letting crawlers in.
Your customers no longer search only on Google. Many ask ChatGPT or Perplexity, or read the AI summary at the top of Google’s results, and decide straight from the answer. The new question: is your name in those answers?
What is GEO?
The term comes from a paper titled “GEO: Generative Engine Optimization” by researchers from Princeton and other institutions. They define generative engines as engines that use language models to gather information from multiple sources and summarise it into an answer, and propose GEO as a framework to help content creators appear in those answers. They found that optimising content can raise its visibility in answers by up to 40%, with the effectiveness of methods varying by domain.
What does Google say?
On its page “AI features and your website”, Google states clearly that there are no additional requirements to appear in AI Overviews or AI Mode. For your page to show as a supporting link, it only needs to be:
- Indexed by Google.
- Eligible to appear in Search with a snippet.
It recommends the SEO basics: allow crawling, internal links, a good page experience, keeping important content as text, structured data that matches the visible text, and an up-to-date Business Profile. And it says you don’t need any AI-specific files.
So the foundation of GEO is good SEO. What GEO adds is writing in a way that makes your content easy to quote.
What makes your content a source that gets quoted?
- The answer first: a short paragraph that answers the question directly, then the details. Models look for a sentence that answers.
- Numbers with sources: a specific number with its source beats “a large share”. (That’s why all our articles end with their sources.)
- Clear definitions: “X is …” in one understandable sentence.
- Real FAQs: phrased the way people actually ask, with short answers.
- Real experience: examples and numbers from your own work, not a rewording of what’s already published.
- A tidy structure: headings that describe what’s under them, and lists and tables where needed.
The technical side
- Allow search and AI crawlers in robots.txt (such as Googlebot, Bingbot, OAI-SearchBot, PerplexityBot and ClaudeBot) if you want to appear in their answers.
- Structured data for your organisation, articles, FAQs and services, provided it matches the page. (See Structured data (schema).)
- One page per topic: a clear service page for each service, and a page for each city you serve, instead of one page that says everything.
- An llms.txt file: an optional text file summarising your site and its main pages. Google says it doesn’t need it, but it does no harm and other tools may read it.
- Consistent company details everywhere: name, city, services and contact methods.
How do you know you’re showing up?
- Ask ChatGPT, Perplexity and Google the questions your customers ask (“best … company in Jeddah”, “how do I …”) and note whether you appear and who does.
- Watch Google Analytics for visits coming from sites such as chatgpt.com and perplexity.ai.
- Track searches for your brand name in Search Console.
Common mistakes
- Producing lots of reworded content with no real addition; Google warns against content mass-produced to attract traffic.
- Blocking AI crawlers and then expecting to appear in their answers.
- Structured data that doesn’t match what visitors see.
- Conflicting information about your company between your site and your accounts.
Frequently asked questions
Is GEO a replacement for SEO?
No. Google says SEO best practices are the same ones that make you eligible for AI features. GEO is a layer on top of SEO that focuses on clear answers and quotability.
Do I need an llms.txt file?
It’s not required to appear on Google, according to Google itself. You can add it as an organised summary of your site, but don’t rely on it instead of good content.
How long until I show up in AI answers?
It depends on how your pages are indexed, the strength of your content, and your competitors. Start with the questions where you have real expertise, and check your visibility monthly.
The bottom line
GEO is good SEO written to be quoted: a direct answer, numbers with sources, real questions, honest structured data, and a site open to crawling. If you want a website built this way from the ground up, have a look at our website service.
