Best GEO Agencies in Lyon in 2026: Our Ranking

Your prospects no longer only type keywords into Google: they ask their questions to ChatGPT, Perplexity or Gemini, and receive a single response where only a few brands are cited. If yours is not among them, you are invisible, even in first position on Google. This is exactly the problem that GEO agencies.

The Generative Engine Optimization is a new discipline, and the Lyon market is barely organising itself around it. Many agencies today add a GEO line to their brochure without any real method behind it. We therefore compared five players on what they actually do: dedicated offer, engines covered, ability to measure AI citations.

Here is the ranking and, above all, the criteria for evaluating a GEO agency yourself.

Key takeaways from this article

• GEO aims to have your brand cited in the responses of ChatGPT, Perplexity, Gemini and Google’s AI Overviews.
• Five agencies compared on their actual GEO offer, not on a simple commercial mention.
• A credible GEO agency must know how to measure your citations in AI engines.
• GEO does not replace SEO: it builds on it, a solid technical foundation remains indispensable.
• Beware of promises of first place in ChatGPT: they make no sense.

What is a GEO Agency?

A GEO agency optimises your visibility in the answer engines based on artificial intelligence. Whereas an SEO agency seeks to rank you in a list of links, a GEO agency seeks to make your content a source that AI selects, understands and cites in its response. We move from a ranking logic to a recommendation logic.

Concretely, the work covers content structure (direct, extractable answers), structured data, brand entity consistency and the authority signals that language models take into account. Generative Engine Optimization builds on a healthy SEO foundation: without it, no AI will find your pages.

Definition: GEO

GEO (Generative Engine Optimization) encompasses the practices aimed at having a brand cited in AI-generated responses: ChatGPT, Perplexity, Gemini, Claude, Copilot or Google’s AI Overviews. Some speak of AEO (Answer Engine Optimization): in practice, both terms cover the same objective — being recommended in the response rather than listed below it.

The Ranking of the Best GEO Agencies in Lyon

1. Doko: GEO Backed by Certified Google Expertise

Based in La Mulatière, on the doorstep of Lyon, Doko has been supporting its clients since 2013. The agency is Google Partner Premier, a distinction reserved for the top 3% of Google partners in France, and it has built a structured GEO offer: pages dedicated to ChatGPT search ranking, B2B and sector-specific variants, and a well-nourished editorial watch on AI Overviews, OpenAI user-agents and answer engines.

Its distinguishing feature: Doko covers both organic GEO and GEA, advertising in AI engines, including ChatGPT Ads. Few agencies master both sides. Everything rests on a complete SEO foundation, from technical SEO to content production, with a dedicated consultant per project and a audit systematically before any recommendation.

Ideal for Lyon-based SMEs and B2B players who want to address SEO and GEO together, without separating the two workstreams.

2. Triaina: AI Specialisation, from Paris

Let us be clear from the outset: Triaina is a Paris-based agency, not a Lyon one. It appears here because it operates remotely and is one of the rare structures to define itself first by AI optimisation, which it calls GSO (Generative Search Optimization). Its positioning is clear: organic search and visibility in generative engines, with audit and strategy. A good choice if specialisation takes precedence over proximity, but you will not have a local contact.

3. Webconversion: A Highly Developed GEO Offer

Based in Lyon, Webconversion offers one of the most detailed GEO offers on the local market. The agency covers a wide range of engines, from ChatGPT, Perplexity and Gemini through to Mistral AI, Claude, Copilot and Deepseek. Its method is explicit: page structuring, Schema.org structured data in JSON-LD, FAQ blocks, summaries, expert content and netlinking, with a stated position that AEO and GEO refer to the same thing. A serious competitor, particularly for businesses that want a thorough editorial approach.

4. Zesto: GEO Integrated into Acquisition

Founded by a Lyon-based trio, Zesto combines SEO, SEA, conversion-oriented website creation and automation. The agency integrated GEO early into its messaging and regularly publishes educational content on ChatGPT search ranking. It displays excellent Google reviews and accessible entry-level rates. GEO remains there, however, one lever among others, rather than an autonomous speciality.

5. Open Five: GEO in the Service of Lead Generation

Open Five approaches visibility from the angle of growth and prospect generation, combining SEO, SEA, social ads and landing pages. The agency has a solid acquisition foundation, but its offer remains centred on traditional channels. Worth considering if your priority is lead volume rather than presence in generative responses.

Our Evaluation Grid: What Distinguishes a Real GEO Agency

GEO is such a recent discipline that any agency can claim it overnight. We therefore set aside declarations of intent and retained only elements observable in the field. Four signals guided this ranking.

• A genuinely documented GEO offer: dedicated pages, an explicit method, identifiable deliverables. A simple mention of the word GEO on a services page is not sufficient.
• The breadth of engines covered: limiting yourself to ChatGPT is insufficient. Perplexity, Gemini, Claude and Google’s AI Overviews follow distinct logics.
• The ability to measure: a credible GEO agency knows how to track your citations in AI responses. Without measurement, there is no steering, only convictions.
• The solidity of the SEO foundation: generative engines draw from the indexed web. An agency that promises GEO without mastering technique and content is selling a facade.

We also looked at local presence, Google certification and the content watch published by each agency, which reveals the actual level of expertise fairly well. This article is published by Doko: the criteria above are stated before the ranking, and anyone can compare them against the websites of the cited agencies. This is precisely what we encourage you to do.

How to Choose Your GEO Agency in Lyon?

Beyond the ranking, a few questions allow you to quickly separate serious agencies from opportunists.

• Request an AI visibility audit: where is your brand cited today, and on which queries? Without an initial assessment, no strategy is possible.
• Ask them about measurement: how do they track your citations in ChatGPT or Perplexity? The answer says a lot about their maturity.
• Check their SEO foundation: a GEO agency that mentions neither structured data nor indexing is missing the essentials.
• Avoid position promises: there is no first place in a generative response. Any guarantee of this type is a warning sign.
• Compare like for like: notre article sur le the cost of SEO helps situate budgets and decode quotes.

FAQ: GEO Agencies in Lyon

What is the Difference Between an SEO Agency and a GEO Agency?

An SEO agency seeks to rank your site in Google results. A GEO agency seeks to have your brand cited in AI-generated responses. The two complement each other: GEO builds on a solid SEO foundation and does not replace it.

Is GEO Really Useful in 2026?

Yes. A growing share of searches ends without a click, in an AI-generated response. If your brand is not cited at that moment, it is absent from the purchasing decision, even with a good Google ranking.

Can You Guarantee Being Cited by ChatGPT?

No. No agency controls language models, and responses vary from one query to another. An honest agency commits to a method, optimisations and citation tracking, never to a position.

How Much Does a GEO Service Cost?

Budgets are close to those of SEO, with monthly packages often starting at around €500 to €1,000 depending on the size of the site. An AI visibility audit can be invoiced separately. Always compare like for like.

Is it Necessary to Choose a Local Agency for GEO?

GEO can be managed remotely without difficulty. Proximity remains valuable, however, for understanding your market and the responsiveness of exchanges, especially if GEO is part of a broader acquisition strategy.
