GEO: The Optimization Google Won’t Tell You About (and That Changes Everything in 2026)

You’re ranking first on Google. Your reviews are excellent. Your Google Business listing is complete. And yet, when a patient, customer, or tourist asks ChatGPT “what’s the best dentist in Paris 15th?” or “a good Italian restaurant in Le Marais?”, your business appears nowhere.

It’s not a bug. It’s a blind spot that 95% of professionals still overlook: AI assistants don’t work like Google. They don’t rank websites. They recommend businesses. And the rules for being recommended are radically different from traditional SEO.

Welcome to the era of GEO — Generative Engine Optimization.

Your Customers No Longer Search the Way They Used To

Think about the last time you searched for a healthcare provider, a restaurant, or a hotel. Did you type a query into Google and click through ten blue links? Or did you ask ChatGPT, Perplexity, or your phone’s assistant?

The numbers speak for themselves. ChatGPT now processes roughly 2.5 billion queries per day, with over 800 million weekly active users. Perplexity, the AI search engine specialized in sourced answers, exceeds one billion monthly queries. And Google itself has rolled out its “AI Overviews” — AI-generated responses — on more than a quarter of its search results.

The shift is structural. Conversational searches are progressively replacing keyword searches. Instead of typing “dentist implant Paris 15,” a user now asks: “I’m looking for a trustworthy dentist for an implant in the 15th arrondissement, which one do you recommend?” The difference is fundamental: the user doesn’t want a list of results. They want a recommendation.

What GEO Changes Compared to SEO

SEO (Search Engine Optimization) optimizes your presence to appear in a list of results. GEO optimizes your presence to be cited, mentioned, and recommended in a response generated by an artificial intelligence.

Here’s what differentiates the two approaches in practice.

With SEO, you aim for a position in a ranking. Your goal is to be in the top 3 Google results so the user clicks your link. Your website is the main entry point. Your levers are keywords, backlinks, load speed, and content.

With GEO, there’s no ranking in the traditional sense. The AI synthesizes information from multiple sources — your website, your Google reviews, your Doctolib profile, directories, articles mentioning you — and decides whether to recommend you or not. Your goal is no longer to be clicked, but to be named in the response.

This is a crucial distinction. Roughly 60% of Google searches already result in no click to any website. That figure rises to 93% in Google’s AI mode. Information is consumed directly in the response. If you’re not in that response, you’re invisible — even if your site is technically well ranked.

How AI Decides Whether to Recommend You (or Not)

AI search engines don’t use a traditional ranking algorithm. They use language models that evaluate the reliability, consistency, and relevance of the information available about you across the web.

Here are the main criteria that influence your visibility with AI.

Consistency of Your Information Everywhere Online

If your name, address, phone number, and hours are identical on your website, Google Business, Doctolib, PagesJaunes, and other directories, the AI considers your information reliable. If inconsistencies exist — an old number here, a slightly different address there — the AI hesitates to cite you because it can’t guarantee the accuracy of what it would say.

Richness and Freshness of Your Content

Data shows that recently updated content is cited significantly more often by AI than dated content. Pages displaying a recent update date get almost twice as many citations. AI favors sources that demonstrate recent activity: recent reviews, recent posts on your Google listing, updated content on your site.

Reviews and Social Proof

Google reviews are no longer just a trust factor for humans. They’ve become a primary data source for AI. When a patient writes “excellent orthodontist, impeccable result for my alignment,” the AI extracts these keywords and associates them with your practice. The more your reviews contain specific terms related to your services (“implant,” “dental emergency,” “whitening”), the more the AI associates you with those queries.

Structured Data (Schema.org)

Structured data is a technical language your website uses to communicate directly with search engines and AI. It’s like a digital ID card that clearly says: “I’m a dentist, located at this address, offering these services, with these hours and this average rating.” Websites that use this markup see their AI citations increase by roughly 30 to 44% according to recent studies.

Presence on the Platforms AI Consults

Each AI platform has its preferred sources. ChatGPT relies heavily on Wikipedia, review sites, and editorial content. Perplexity frequently cites Reddit, YouTube, and specialized sites. Google AI Overview draws from its own index, with a preference for Google Business listings and sites with structured data. Being present and optimized on the platforms each AI consults is the key to an effective GEO strategy.

Why SEO Alone Is No Longer Enough

Let’s be clear: SEO isn’t dead. Ranking well on Google is still important. But SEO alone now has a major flaw: it no longer guarantees visibility.

Research shows that only 14% of URLs cited by Google’s AI mode appear in the top 10 traditional search results for the same query. In other words, 86% of sources cited by AI are not the top Google positions. Ranking first on Google doesn’t mean being cited by AI.

The explanation is simple. AI isn’t looking for “the site best optimized for a keyword.” It’s looking for “the most reliable and complete source to answer a specific question.” These aren’t the same thing.

A dental practice with an average website but excellent Google reviews, a complete Doctolib profile, mentions in professional directories, and proper structured data can easily be recommended by ChatGPT, while a practice with a perfectly SEO-optimized site but no presence elsewhere will be ignored.

GEO: What It Concretely Changes for Your Business

If you’re a dentist, restaurant owner, or hotelier in Paris, here’s what GEO means in practice.

Your Google Business Listing Becomes Your Most Important Asset

Your Google Business Profile is no longer just a local SEO tool. It’s one of the most consulted sources by all AI platforms. The information you put there — categories, services, description, photos, posts, Q&A — directly feeds the responses of ChatGPT, Perplexity, and Google AI. An incomplete or inactive listing makes you invisible to AI.

Reviews Become a Strategic Lever

Every review is a micro-page of content that AI analyzes. Encouraging your patients or customers to mention specific services in their reviews (“very satisfied with my dental implant,” “the Sunday brunch is excellent”) strengthens your association with those queries in AI models.

Your Website Must Speak to Machines as Much as to Humans

Structured data (Schema.org) is no longer a “technical bonus.” It’s become a prerequisite for AI visibility. A site without structured markup is like a shop without a sign: AI walks right past it.

Multi-Platform Presence Is Mandatory

Being only on Google is no longer enough. AI cross-references information from Google, Doctolib, TripAdvisor, TheFork, PagesJaunes, professional sites (French Dental Association), social media, and specialized directories. Each additional platform where you’re present with consistent information strengthens your credibility in the eyes of AI.

How to Measure Your AI Visibility

The question every professional asks: “How do I know if AI is recommending me?”

The most direct method is to test it yourself. Go to ChatGPT, Perplexity, and Google, ask the questions your customers would ask (“best dentist for implant Paris 15th,” “cheap Italian restaurant Le Marais,” “boutique hotel Saint-Germain”) and see if you appear.

To go further, specialized tools are beginning to emerge for systematic AI visibility tracking. But the principle remains the same: in GEO, you no longer measure your “position” in a ranking. You measure your citation frequency — how often AI mentions you when asked questions related to your business.

At Eddie Miller Agency, we’ve developed a GEO score out of 100 that precisely evaluates this visibility across 15 criteria, testing your presence on ChatGPT, Perplexity, Google AI Overview, and the major AI engines. This score lets you know exactly where you stand and what to improve first.

5 GEO Actions to Take This Week

You don’t need to redo everything to start gaining AI visibility. Here are five concrete actions, ranked by impact.

1. Complete your Google Business listing to 100%. Every field matters: detailed description (750 characters minimum), all your services listed, up-to-date hours, recent photos, booking link. These are the baseline data AI consults first.

2. Ask your next 10 satisfied customers for a detailed review. Not just “great practice.” Ask them to mention the service received: “Excellent follow-up for my orthodontic treatment with Dr. X.” These keywords in reviews directly feed AI recommendations.

3. Check the consistency of your information across 5 key platforms. Your name, address, and phone number must be strictly identical on Google Business, your website, Doctolib (or TripAdvisor/TheFork for restaurants), PagesJaunes, and a professional directory in your industry.

4. Publish a Google Business post this week. A simple post with a service, a keyword, and your arrondissement: “Professional teeth whitening at the practice — Paris 15th, Convention metro. Book on Doctolib.” This freshness signal counts for AI.

5. Test your AI visibility. Go to ChatGPT and Perplexity, ask 3 queries your customers would use, and note whether you appear. If the answer is no, you now know why — and what to do.

GEO Is Not a Trend, It’s the New Standard

The global GEO market was worth less than one billion dollars in 2024. It’s expected to exceed 7 billion by 2031, with an annual growth rate of 34%. Businesses that adopt a GEO strategy see an average 40% increase in online visibility and a return on investment 22% higher than traditional SEO strategies alone.

For local businesses in Paris — medical practices, restaurants, hotels — the stakes are particularly high. Local search is the natural playing field for AI: when a user asks for a geolocated recommendation, the AI must deliver a precise and trustworthy answer. Businesses that have put the right signals in place will be systematically recommended. The rest will be systematically ignored.

SEO allowed you to be found. GEO allows you to be recommended. And in a world where decisions are increasingly made in a conversation with AI, being recommended makes all the difference.

FAQ — Frequently Asked Questions About GEO

What exactly is GEO?

GEO (Generative Engine Optimization) is the set of techniques that allow a business to appear in recommendations generated by artificial intelligences like ChatGPT, Perplexity, Google AI Overview, and Gemini. Unlike SEO, which aims for a ranking in a list of results, GEO aims to be cited and recommended in a conversational response.

Does GEO replace SEO?

No. SEO and GEO are complementary. SEO remains essential for organic traffic and Google presence. GEO adds a layer of visibility in AI environments, which represent a growing share of searches. Ignoring either one creates a blind spot.

How long does it take to see GEO results?

Initial results can appear within a few weeks for the most direct actions (Google Business listing optimization, online information consistency). Deeper results (regular AI citations, GEO score improvement) typically take 2 to 3 months of continuous effort.

Is GEO relevant for a small practice or an independent restaurant?

Absolutely. GEO is actually more impactful for small local businesses than for large chains. AI looks for local relevance and specificity. A well-optimized independent dental practice in its arrondissement can be recommended before a large chain with weaker local presence.

How do I know if ChatGPT recommends my business?

The simplest test: go to chat.openai.com and ask the question a customer would ask, for example “Which dentist do you recommend in the 15th arrondissement of Paris?” If you don’t appear, a GEO audit will let you identify precisely why and how to fix it.
