Best GEO agencies in France 2026: ranking of the 91 Generative Engine Optimization agencies

Updated 22/09/2026. 91 agencies scored · 1 020 ChatGPT runs analysed · 21 publishing an entry price.

GEO, or Generative Engine Optimization, is the work of getting a brand named inside answers produced by generative engines such as ChatGPT, Perplexity, Gemini, Claude, Copilot and Google's AI Overviews. This page ranks the 91 GEO agencies operating from France. Each one is scored out of 100 from public data and from a visibility measurement run on ChatGPT: 1 020 executions of the same prompt set, carried out from France between 8-21 sept. 2026. Nothing here is paid for, sponsored or estimated.

The French market uses several names for the same discipline. GEO is the most common among agencies. AIO (Artificial Intelligence Optimization) and AEO (Answer Engine Optimization) describe the same goal with a different emphasis. SEO IA and référencement IA are the French-language equivalents, used mostly by agencies coming from traditional search. This ranking treats all five as synonyms, because what is being measured is the same: the ability to get a client named in a generated answer.

How the score is calculated

Six criteria add up to 100 points. No payment gets an agency in or moves it up. Missing information earns nothing and is never estimated: the French fiche then shows « Non communiqué », meaning not disclosed.

Criterion	What is measured	Points
AI visibility	Citation rate across 1 020 ChatGPT runs, scaled to the best result in the panel	25
Client reviews	Bayesian average of Google and Trustpilot ratings, prior of 3 over 10 reviews	20
Public proof	Quantified client cases published on the agency's own website	20
GEO offering	Breadth of services (out of 7) and engines covered (out of 6)	15
Transparency	Published pricing and published methodology	10
Measurement	Named tracking tools and a GEO audit sold as an identifiable service	10

AI visibility carries the most weight because it is the only criterion that records a result rather than a claim. The median score across the 91 agencies is 27,1 out of 100, and the average ChatGPT citation rate is 6,0 %. Full details are published in French on the methodology page, including the list of structures that were excluded and why.

Choosing a GEO agency in France

Check the measurement before the pitch

A GEO engagement without a tracking tool cannot be verified. Ask which tool tracks citations, how often, and on which prompt set. Generative answers vary between runs, so a stable prompt set repeated on a schedule is the only way to observe progress. 30 of the 91 agencies publicly name at least one measurement tool.

Check engine coverage

Being cited by ChatGPT tells you nothing about Perplexity or Google's AI Overviews, which draw on different sources. This ranking records up to 6 engines per agency. An agency tracking a single engine gives you a partial picture.

Ask for a quantified client case

A quantified case names a metric and gives a before and an after. 11 of the 91 agencies publish at least one. This is the criterion that separates established firms from recent offerings most clearly.

Ask the entry price in the first conversation

21 of the 91 agencies publish an entry price on their website. The rest disclose pricing only in a meeting, which is not disqualifying but makes comparison slower.

GEO agencies by city

63 of the 91 agencies disclose their head office city, spread across 32 French communes. Cities with at least two agencies have a dedicated page, published in French.

Frequently asked questions

Which is the best GEO agency in France?

On this 2026 ranking, Archipel Marketing comes first with 94,1 points out of 100, ahead of Eskimoz (70,5) and Empirik (56,9). The result combines measured ChatGPT visibility, client reviews, published proof, breadth of offering, pricing transparency and measurement tooling. Which agency is best for you depends on your sector and budget: every French fiche states who the agency is suited to.

How much does GEO cost in France?

21 of the 91 agencies publish an entry price, starting at 990, 1 750 € TTC, 1 500 € and rising with scope. Standalone GEO audits are priced separately by 36 agencies. No figure is estimated: every amount is taken from the agency's own website and dated.

What is the difference between GEO, AEO and SEO?

SEO optimises ranking in a list of links. AEO targets the direct answer, whether a featured snippet or a voice assistant. GEO targets citation inside a text generated by a language model. The three overlap heavily, since a clear, factual, well-structured page serves all of them. The difference lies in measurement: GEO is counted in citation rate, not in position.

Does GEO replace SEO?

No. Generative engines rely heavily on indexed web pages, and part of their citations comes from conventional search results. A site invisible in Google is unlikely to be cited by ChatGPT. GEO adds a layer of work on citability; it does not remove the technical and editorial groundwork of search.

Can a French GEO agency work with an international company?

20 of the 91 agencies state that they operate outside France. The constraint is linguistic rather than technical: prompt sets, cited sources and competing brands differ by market, so a separate measurement panel is needed per country. Ask how many countries the agency tracks in parallel.

Is this ranking paid or sponsored?

No. No position can be bought, no link is sponsored and no agency funds its presence. The ranking is published by Rankly. The publisher is itself active in the GEO market, which is stated plainly on the about page: the scoring formula and the source data are published so that anyone can reproduce the calculation.
