Have you typed your company’s name into ChatGPT recently? If the response made you cringe (or worse, if it didn’t even mention you), it’s time to take GEO seriously. Because by 2026, your customers won’t just ‘Google’ things any more: they’ll ask an AI directly to find them the right answer. If your content isn’t designed to be understood and processed by these models, you’ll become invisible in this new way of searching for information. A new generation of agencies has specialised in this already strategic field, but there’s sometimes a world of difference between SEO agencies that simply tack ‘GEO’ onto their website and the true experts in the field!
We’re here to help you make the right choice: definitions, selection criteria, prices and a ranking of the 10 best GEO agencies in France in 2026.
Key takeaways:
In summary, the best GEO agency combines proven expertise in generative AI, tailored monitoring tools and an approach that complements SEO. Compare references, methods, tools and the transparency of the services on offer to choose a partner capable of boosting your visibility, regardless of which search engine your customers use.
GEO is the art and science of optimising your visibility in the responses generated by conversational AIs such as ChatGPT, Perplexity, Gemini, Claude and Google’s AI Overviews.
A translation for the uninitiated: forget that little ritual of ‘typing in three keywords, scrolling down the Google page, clicking on the first blue link’. These days, users simply ask their question as if they were talking to a mate (well, a mate who’s swallowed up all the knowledge on the internet), and the AI gives them a straight, no-nonsense answer. Your website might not even get visited: your brand is just mentioned. Or not. 😅
SEO aims to rank a page in a list of results. GEO, on the other hand, aims to ensure that your brand is mentioned, understood and recommended directly within an AI-generated response (without necessarily requiring a click). The principles governing content structure, authority and ‘citability’ are undergoing profound changes: LLMs do not read the web in the same way that Google crawls it.
💡And as a picture is worth a thousand words: SEO is the art of ranking highly on a supermarket shelf – the more visible your product is at the front of the shelf, the more likely it is to be chosen. GEO, on the other hand, is different: it’s about convincing the sales assistant (the AI) to recommend your product directly to the customer, without them even having to browse the shelf.

User behaviour is changing at breakneck speed! More and more people are asking an AI their questions directly, rather than typing a query into a search engine. A brand that isn’t featured in generative answers is missing out on an entire acquisition channel which, unlike SEO, is still relatively uncontested… for now.
GEO draws on skills that are still rare in the market, such as data structuring (schema.org, entities), semantic clarity, and a presence in the sources that LLMs use to train or to carry out real-time ‘research’.
Gone are the days when the average Google ranking was enough to tell the whole story. In GEO, we look at more than that:

Be wary of agencies that have simply renamed their SEO service ‘GEO’ without changing their approach in any way. Ask for concrete examples of results achieved on ChatGPT, Perplexity or AI Overviews. 🔍
GEO cannot be managed blindly or on a hunch. A good agency has tools (whether its own or from third parties) to monitor changes in your visibility within generative responses.
GEO does not replace SEO; it complements it. An agency that sells you one by pitting it against the other has probably not fully understood the subject.
Ask for specific examples, with before-and-after results for specific search queries.
Here, we pay close attention to the wording used in the quote. A “free audit”, for example, may simply be a marketing ploy with no real analytical value. An “all-inclusive package” may, once the contract has been signed, exclude certain services that are nevertheless essential (copywriting, technical markup, monitoring of AI-generated content). A “one-off assignment” may also conceal the absence of any long-term support.

💬 Our expert’s perspective
“As Head of SEO and Associate Director at Ad’s Up Consulting, I see the market accelerating on a daily basis. Adobe’s recent acquisition of Semrush for nearly $2 billion sends a strong signal: SEO/GEO is no longer an isolated channel, but a central pillar of companies’ overall digital strategy. At Ad’s Up Consulting (EDG Group), this is a very real reality: demand for GEO is skyrocketing.”
But why, and what does that mean?
GEO: The Real Target 🎯
The focus is on visibility data in large language models (LLMs). Adobe is set to integrate Semrush into Experience Cloud to enable brands to measure and optimise their presence in generative responses.
🧑💻 Adapting skills
The days of the ‘SEO technician’ are over. Our role is evolving towards analysing and coordinating data across content creation, analytics and visibility platforms.
⚒️ Stack Unification
No more silos. Creation (Creative Cloud), Experience (AEM) and Performance (Semrush) are merging. Look forward to native integration that redefines MarTech efficiency.
This acquisition is not a signal; it is a catalyst. It confirms that the role of the SEO/GEO expert is now to manage visibility data within major software suites in order to drive performance.
It is an agency specialising in optimising a brand’s visibility within the responses generated by conversational AI systems (ChatGPT, Perplexity, Gemini, AI Overviews), as opposed to traditional search engine optimisation (SEO) in search results.
No, it complements it. SEO remains relevant for capturing traffic from traditional search engines, whilst GEO specifically targets visibility within generative responses. Both strategies benefit from being managed together.
By tracking the brand mention rate in AI responses, the share of generative voice for key industry queries, and changes in referral traffic from conversational AI systems.
Allow for a flat-rate fee of between €1,000 and €2,500 per month, with an initial audit sometimes charged separately at between €1,500 and €4,000.
Because it integrates GEO into a comprehensive content strategy (SEO + GEO), with transparent monitoring of brand mentions and a methodology that evolves alongside AI models, rather than a static offering. 🎯
GEO isn’t just a passing trend; it’s a fundamental shift in the way your customers search for and find information. You might as well jump on the bandwagon rather than stay on the platform taking a low-key approach! With its integrated SEO + GEO approach, Ad’s Up helps you stay visible, whatever search engine your customers use. Want to find out where you stand today?
