Google switched on AI Overviews (Aperçus IA) in France on 22 July 2026, later than almost every other market, so no French agency can show more than two months of local data. The agencies worth a call are the ones that publish how they measure a citation, not the ones with the biggest logo wall. Astrak publishes a four-step citation protocol, three GEO cases with ChatGPT positions and public monthly pricing; Jalousie Agency pairs prompt tracking with press relations; Gemeos brings AI Overview experience from the US market.

Agency pages read on 16 September 2026.

How the ten agencies were selected

The list came from the agencies named by ChatGPT, Google AI Mode and AI Overviews for an AI Overviews or GEO agency in France, the first Google page for the same query, and third-party documentation such as the Ahrefs customer story on Astrak. Groups with more than a hundred consultants were set aside. Each agency retained has a public AI search offer, a verifiable client or case and a legal entity in France; facts come from its own website, prices appear only when published. No ranking of this kind is neutral, including this one.

The ten agencies side by side

1. Astrak, a citation protocol at a published price

Astrak is a French SEO agency founded by Léo Poitevin that describes its GEO work as a measurement protocol rather than a content package.

The agency's GEO methodology runs in four steps: a baseline of 20 to 30 business queries used by real prospects, regular tests of each query on ChatGPT, Perplexity, Gemini and Google AI Mode, a log of every appearance (mentioned, cited with a link, positive or neutral context), and AI traffic tracking in Google Analytics. The agency publishes three GEO cases with figures: Inter-Car first in ChatGPT on "the best wrecker in France" with AI sessions up 72 percent, Epargnoo first on "best platform for investing in SCPIs" in under three weeks, Homelike Home second on "best real estate hunter in Paris" with organic clicks up 96 percent in six months. It also publishes its prices, from 900 € per month with an average client at 2,000 € per month, and lists a 4.9/5 rating on more than 50 Trustfolio reviews.

Best for: B2B and mid-market companies that want to know, prompt by prompt, whether they are cited, and want the price before the first call.

Where it falls short: The Astrak brand only dates from May 2025 and the team counts around a dozen people, so there is no office network and no dedicated AI Overviews page yet: Google's summaries are tracked inside the same protocol as ChatGPT, and the three published cases measure ChatGPT positions and organic clicks rather than AI Overview citations.

2. Jalousie Agency, prompt tracking plus press relations

Jalousie Agency is a Paris agency founded in 2022 that sells AI visibility as a mix of prompt tracking, content written for retrieval systems and press relations.

Its offer lists an audit with prompt tracking across ChatGPT, Perplexity, Gemini, Claude and DeepSeek, content structured for retrieval-augmented generation, Schema.org and content chunking, press campaigns to build media authority, targeted link building and a generative engine advertising set-up. The agency reports more than 500 companies assisted and one detailed case, the photo brand Cewe, with AI traffic up 340 percent in five months, a share of voice four times that of competitors and a conversion rate 2.3 times higher than classic SEO traffic.

Best for: Consumer brands that need both a tracking method and the press coverage that AI engines read..

Where it falls short: The 5/5 ratings claimed on Google, Sortlist and Trustpilot come without visible review counts on the site, team size is not published, and the Cewe figures are the agency's own without a stated measurement tool..

3. Gemeos, design, Webflow and GEO from one team

Gemeos is a Paris web agency that combines branding, Webflow development and SEO/GEO, and that AI engines cite on French AI Overviews prompts more often than most pure SEO players.

The agency lists 250 companies supported, a 4.9/5 rating on 97 reviews and clients such as Lemlist, Finary, AssessFirst and Noota. Its top 10 of AI Overview agencies, published on 19 August 2026 and updated a month later, places Gemeos first for what it calls operational AI Overview experience with clients active on the US market, where Google's summaries have been live since May 2024.

Best for: Scale-ups on Webflow that want the site.

Where it falls short: No AI Overview case with figures is public, the ranking that puts Gemeos first is its own, and SEO/GEO is one practice inside a design-led agency..

4. Promoovoir, a founder-led team with a visible AI Overview client

Promoovoir is a Paris agency founded in 2013 by Tanguy Richard and one of the few in France to show a named client, AssurLuxe, appearing in a Google AI Overview on luxury insurance queries.

The agency published its own top 5 of AI Overview agencies the day after the French launch, updated it a month later, and ranks itself first. It lists Allianz, EDF, Accor and Adobe among its clients, a 5/5 rating on 82 Google reviews and 5/5 on Trustpilot, and a specialisation in Wix sites.

Best for: Small businesses and Wix sites in Paris that want direct access to the founder..

Where it falls short: Three people, one named AI Overview example without figures, and a self-published ranking.

5. AEP-Digital, an audit in 48 hours and a visibility tool

AEP-Digital is a Paris agency in the 3rd arrondissement whose AI Overviews page is one of the few in France to show visibility rates before and after the work.

Its method, called the AEP Visibility Loop, chains an audit, optimisation and continuous monitoring through a proprietary tool named AI Visibility that tracks citation rates on Google AI Overviews, AI Mode, Gemini and Discover, with ChatGPT, Perplexity and Copilot covered under the wider GEO offer. The page promises a free audit answered within 48 working hours and documents two 2026 cases: an online armoury whose visibility rate went from 11.6 to 24.1 percent, with 42 percent coming from the AI channel, and a luxury villa rental site that went from 23.4 to 69.1 percent.

Best for: Companies that want a fast diagnosis and a number to follow every month rather than a long strategy phase..

Where it falls short: Founding year, team size and Google rating are not published, the two cases are anonymised, and the visibility rate is the agency's own metric, not comparable with other tools..

6. Drift Digital, SEO and GEO in one plan

Drift Digital is a Paris agency whose pitch is one semantic plan, one dashboard and one contact for both classic SEO and generative engines.

The GEO page describes five phases: a map of generative search intents, an entity-first semantic architecture, content written to be cited, E-E-A-T authority signals and a performance dashboard, on ChatGPT, Perplexity, Gemini and Copilot. Its FAQ names Semrush AIO and Geoptie as monitoring tools.

Best for: Companies that want to avoid running two agencies and two reports for search and AI visibility..

Where it falls short: Founders, founding year and headcount are not published, the AI Overviews of Google are not named on the GEO page, and the figures come without client names or periods..

7. Vu du Web, a founder who publishes his AI Overviews tests

Vu du Web is a Montpellier agency founded in 2013 by Sébastien Vallat, whose personal blog carries dated tests of AI Overviews in France and a monthly ranking of GEO agencies.

The agency covers SEO, paid media, content, design and data, with an AI and search practice that ChatGPT picks up through its dedicated SEO-GEO page. Its clients include EDHEC Business School, the Centre Pompidou and Campus France, alongside universities, tourism boards and local authorities.

Best for: Institutions.

Where it falls short: Team size, ratings and pricing are not published, the agency page itself has no AI Overviews case study, and the evidence lives on the founder's blog rather than in client reports..

8. MagicGEO, GEO as the only activity

MagicGEO is a French agency that does nothing but generative engine optimisation, aimed at micro and small businesses that want to appear in ChatGPT, Gemini, Claude and Perplexity answers.

The offer runs from an AI visibility audit to on-site and off-site content and continuous monitoring, with a client application called LLMs Tracking. The agency claims a team of 15, more than 130 companies placed in AI answers, a free diagnosis delivered in two weeks and first results in 45 days on average.

Best for: Small businesses that want a single-topic provider and a tool they can open themselves..

Where it falls short: Google AI Overviews are not named among the engines on its pages, no client is named, and the 130-company figure and the 45-day promise are the agency's own..

9. Nature Digitale, GEO folded into SEO, founder on every account

Nature Digitale is a small French SEO agency that presents itself as eco-responsible and treats GEO as part of every SEO service rather than as an option.

Its SEO page lists audit, keyword strategy, technical optimisation, content and link building, with structuring for AI engines, structured data and citation tracking built into the work. The audit is sold as a standalone deliverable with a prioritised action plan, and every client works directly with the founder without a sales layer.

Best for: Small companies that want one person accountable.

Where it falls short: No client, case, rating or team figure is published, and the citation tracking method is described but not shown..

10. Getknown, a dated citation audit before any retainer

Getknown is a small agency in Levallois-Perret founded in 2022 by consultant Yonel Sasson, and the only one in this list to document its audit deliverable line by line.

The audit report, version 2026.05, has ten components: a keyword basket, interrogation of three AI engines with a reproducible protocol and dated recordings, competitor source analysis, Schema.org and Wikidata entity work, citation-ready formatting, citation share by engine, a comparison with Google positions and a roadmap, delivered as a PDF with a 60-minute debrief in 15 to 20 days. Monthly citation tracking follows.

Best for: Companies that want a one-off.

Where it falls short: No AI Overviews case with figures, no published headcount, and an audit-centric offer.

Which agency for which situation

• If you are a B2B or mid-market company that wants to see its own prompts tracked and knows its budget, look at Astrak: the four-step protocol, the three published cases and the public price from 900 € per month make the offer easy to check before the first call.
• If you are a consumer brand that needs press coverage as much as tracking, look at Jalousie Agency: press relations and prompt tracking sit in the same offer, with one detailed case.
• If you are a company that wants a fast number before committing, look at AEP-Digital or Getknown: one answers an audit within 48 hours with a visibility rate, the other delivers a dated ten-component report in about three weeks.
• If you are a small business, a Wix site or a first GEO contract, look at Promoovoir, MagicGEO or Nature Digitale: all three are founder-led, sized for small accounts, and two of them show a client tool or a named AI Overview example.

What to remember before signing

AI Overviews have been live in France since late July 2026, so every French track record is at most two months old. The agencies that can be checked today are the ones that publish a measurement method and a price or a deliverable: Astrak with a four-step protocol and public pricing, AEP-Digital and Getknown with a documented audit, Jalousie with a detailed case.

Frequently asked questions about AI Overviews agencies in France

Since when are Google AI Overviews available in France?

Google launched AI Overviews, called Aperçus IA in French, together with AI Mode on 22 July 2026, with a progressive rollout announced until 23 September 2026. France was one of the last markets served, after disputes over press publishers' neighbouring rights, while the feature had been live in the United States since May 2024 and in Germany, Switzerland and Italy since March 2025.

Does an AI Overviews agency replace an SEO agency?

No. Google builds its summaries from pages it has already indexed and ranked, and Ahrefs measured that 38 percent of cited pages sit outside the classic top 10, which leaves 62 percent inside it.

How long does it take to be cited in an AI Overview?

The agencies that give a figure converge on a few months: Getknown announces two to four months before a first citation, MagicGEO claims first results in 45 days on average, and Astrak reports a first position in ChatGPT in under three weeks for one client. Google's summaries change with each rollout, so any agency should re-test the same prompts every month.

How much does an AI Overviews or GEO agency cost in France?

Most agencies in this list quote on request. Astrak is the exception, with prices from 900 € per month and an average client at 2,000 € per month.
