The GEO Guide (Generative Engine Optimization)

How to be cited, recommended and accurately described by AI assistants — ChatGPT, Gemini, Claude, Perplexity and Grok. Everything you need to understand and do to exist in generated answers, explained clearly.

What is GEO?

GEO — short for Generative Engine Optimization — refers to all the practices that aim to make a brand appear, get cited and be recommended in the answers produced by AI assistants.

When someone asks ChatGPT, Gemini, Claude, Perplexity or Grok a question, they don't get a list of ten links: they get one synthesized, written answer that cites a few sources and sometimes explicitly recommends brands or products. GEO is about maximizing your chances of being one of those cited brands — in the right place, in the right context, with an accurate description.

In practice, GEO focuses on three questions: are you present in the answer (citation or mention), where do you appear (first, among others, in passing), and how are you described (recommended, neutral, or with incorrect information). Optimizing these three dimensions is what GEO is about.

In one sentence: where SEO tries to rank a link in a results page, GEO tries to get your brand into the single answer the AI gives your customer.

GEO also overlaps with neighboring terms you may come across: AEO (Answer Engine Optimization), AIO (AI Optimization) or "SEO for AI". Nuances exist, but the goal is the same: being the brand the assistant names when it answers a buying or research intent.

GEO vs SEO: what's the difference?

GEO and SEO share a common foundation — useful, reliable and well-structured content remains essential in both. But what you optimize changes radically: SEO optimizes a ranking of pages, GEO optimizes a written answer. Here are the main differences.

Criterion Classic SEO GEO
Goal A well-ranked link in a results page Getting cited in a single, written answer
Surface Google / Bing results page ChatGPT, Gemini, Claude, Perplexity, Grok
Output format List of blue links + snippets Synthesized answer, cited sources, recommendations
Key metric Position, clicks, impressions Citations, share of voice, position in the answer
Main lever Keywords, backlinks, on-page technical Authority, factual data, presence on sources AI reads
Competition 10 results on the first page 2 to 5 cited brands, the rest invisible
Measurement Search Console, rank trackers Repeated tests on each assistant (e.g. GEO console)

Read the full GEO vs SEO comparison — what transfers from SEO, what doesn't, and when to invest in each.

The practical consequence matters: a strong SEO ranking does not guarantee a citation by the AI, and conversely, a brand can be recommended by an assistant thanks to solid third-party mentions without ranking first on Google. The two disciplines feed each other, but they aren't measured with the same tools.

Another major difference: in SEO, you mostly work on your own site. In GEO, much of the work happens off your site — on the reference pages, comparisons, reviews and directories that AIs consult to compose their answer.

Why now?

Search behavior is changing fast. A growing share of "what's the best…", "which tool for…" or "where to buy…" questions is now asked directly to an AI assistant rather than a classic engine. For these high-intent queries, the AI becomes the first point of contact with your brand.

Three dynamics make this urgent:

  • The answer replaces the list. Users read a synthesis and often stop there. If your brand isn't in it, they don't discover it — and they don't click anywhere.
  • AI is everywhere. Google Search (AI Overviews), browsers, phones, work tools: assistants slip into journeys where classic SEO no longer captures attention.
  • First movers win. AIs build a "memory" of your industry. Brands that structure their presence early get cited durably; latecomers start with a machine-notoriety deficit.

In short: generative visibility is becoming a channel in its own right. The right time to work on it is before your competitors become the assistant's default answer.

How to get cited by AI: the checklist

There's no magic button to "appear in ChatGPT". But there is a set of concrete actions that, taken together, clearly increase your chances of being cited and well described. Here's the essential GEO checklist. For a step-by-step walkthrough, read our guide on how to get cited by ChatGPT, Gemini and Perplexity.

01

Structure your content

Clear headings, direct answers at the start of each section, lists, tables, FAQs, structured data (schema.org). AIs extract organized, explicit content far better than a vague block of text.

02

Build your authority

Displayed expertise, identified authors, citations by reference sites, brand consistency over time. Models favor sources they judge reliable and recognized.

03

Be where AIs read

Wikipedia and knowledge bases, comparisons and "top" lists in your sector, directories, specialized media, communities. Assistants compose their answers from these third-party sources.

04

Provide factual data

Prices, specs, figures, dates, verifiable comparisons. AIs rely on precise facts; factual, up-to-date content is more easily reused — and correctly attributed.

05

Cultivate mentions and reviews

Customer reviews, testimonials, press citations, presence on rating platforms. The more your brand is named positively elsewhere, the more weight it carries in the AI's answer.

06

Make technical access easy

Fast pages, clean HTML, content accessible without blocking, a clear sitemap. If the bots that feed the AIs can't reach your content, you can't be cited. Our llms.txt guide explains how to help AI crawlers read your site.

Mistakes to avoid

  • Keyword stuffing. It doesn't fool generative models and hurts the readability of your answers.
  • Thin or dated content. A page without verifiable information or updates has little chance of being reused.
  • Ignoring off-site. Betting everything on your own domain ignores the third-party sources that drive 80% of the AI's decision.
  • Not measuring. Without tracking, you optimize blindly and never know whether you're actually progressing.

Measure and track

GEO isn't steered by intuition. As with SEO, what isn't measured can't be improved. The catch: classic SEO tools can't see assistants' answers. So you need a dedicated measurement that actually queries the AIs.

The method is to ask the assistants your customers' real questions, several times, on each engine, then analyze the answers. Our measurement methodology details how each engine is queried. The indicators to track are clear:

  • Citations & mentions — how often, and on which questions, the AI names your brand.
  • Position in the answer — do you appear first, among others, or at the bottom.
  • Share of voice — your weight against competitors, assistant by assistant.
  • Trigger prompts — the questions that get you cited (or not), to prioritize your efforts.
  • Accuracy — does the AI describe you correctly, or spread false information?

Tracking these metrics over time and across all five engines reveals the real effect of your actions, surfaces gaps between assistants, and lets you react when a competitor takes your spot. That's exactly what the GEO console features cover: a search-console-style read, but for AI answers.

Best practice: set a baseline today, apply the checklist, then re-measure at regular intervals. The growth of your share of voice is your best indicator of GEO success.

GEO FAQ

Will GEO replace SEO?

No, it extends it. AI assistants rely heavily on well-ranked, well-structured pages: good SEO remains a foundation. GEO adds the "get cited and recommended in the AI's answer" layer that SEO alone doesn't cover.

How long does it take to see results?

It depends on the engines and your starting point. Some assistants reflect new content in days to weeks, others take longer to recompose their "memory" of your brand. Regular tracking measures real progress instead of guessing.

Can you be cited by an AI without ranking well on Google?

Yes. AIs cross-reference many sources — reference sites, reviews, directories, media, forums. A brand can be cited thanks to strong third-party mentions even if its own site isn't first on Google. That's the whole point of building off-site authority.

How do I know if an AI cites my brand today?

By asking the assistants your customers' real questions and measuring whether, where and how your brand appears, on each engine. GEO console automates this test on ChatGPT, Gemini, Claude, Perplexity and Grok, and tracks it over time. More GEO questions are answered in our full FAQ.
