Which is the best Google AI Overviews SEO agency in France in 2026? On 22 September 2026 we reviewed the websites of more than thirty French agencies offering GEO or AI Overviews services (Aperçus IA in French) and kept seven, ranked alongside Astrak. The main criterion is not reputation: AI Overviews and AI Mode launched in France on 22 July 2026, so no agency has more than two months of French data. What can be checked is what each agency publishes: a dedicated offer, a measurement protocol, dated results, a price.
This ranking is separate from our ranking of the best GEO agencies, which covers ChatGPT, Perplexity and every generative engine. Here, only Google counts. Astrak wrote this ranking and puts itself first: the criteria are set out below so you can judge for yourself.
The three AI Overview agencies publishing the most evidence
GEO and AI Overviews SEO agencies in France: what each one publishes
Rather than a score out of 10, the table shows what can actually be found on each agency’s website as of 22/09/2026.

Astrak
SEO and GEO agency, AI Overview service page
Astrak is a French SEO and GEO agency working with B2B and mid-market companies, industrial groups, professional firms and SaaS vendors. Its AI Overview agency page describes a five-step method with a deliverable at each step: a panel of 20 to 30 business queries, a baseline reading on AI Overviews, AI Mode, ChatGPT, Perplexity and Gemini, a positioning audit (what AI engines say about the brand, its offer and its prices), a map of the cited sources, then weekly tracking.
The agency distinguishes mentions, the brand name written in the answer, from citations, the page linked among the sources, and puts the mention rate first in its reporting. Its published cases are measured on ChatGPT and in Google clicks: Inter-Car, the first vehicle recycler recommended by ChatGPT with AI sessions up 72%, or Homelike Home, second on ChatGPT and +96% clicks in six months. It displays a price: from €900 per month, with an average budget of €2,000 per month.
Strengths
- Method published in full, the same for every client.
- Positioning audit included: what AI engines say about the brand, and where errors come from.
- Mention rate tracked separately from citation rate.
- Starting price displayed, 4.9/5 from 50+ Trustfolio reviews, CESEO and QASEO certifications.
Things to check
- Published cases are measured on ChatGPT and in clicks; client cases measured in AI Overviews are still under observation.
- A team of 8: limited capacity for simultaneous engagements.
Stafe
SEO and GEO agency in Avrillé (Angers)
Stafe, based in Avrillé near Angers with 17 years of experience, has no page dedicated solely to AI Overviews but includes them in its GEO offer, updated on 11/09/2026. Its in-house tool, the « Stafe GEO Visibility Report », measures the brand’s citations every month in ChatGPT, Perplexity, Gemini, Claude, Copilot and Google AI Overviews, against its direct competitors. The agency has also published an article on the impact of AI Overviews on traffic (30/06/2026, updated 31/07/2026).
Its price list is the most detailed in the panel: GEO audit from €2,500 to €5,000 excl. VAT, tracking from €850 to €2,500 excl. VAT per month. Its published cases, such as Vert la Pub (+24% quote requests via ChatGPT) or Tréca (AI traffic multiplied by 2.4 in six months), concern AI assistants, and the agency says so itself: it does not yet have enough hindsight for French AI Overviews figures.
Strengths
- Named tracking tool covering AI Overviews every month.
- Public audit and tracking prices.
- Named client cases with figures.
Things to check
- No offer page dedicated to AI Overviews.
- No AI Overviews results specific to France yet.
Vigeon
Independent GEO consultancy in Toulouse
Vigeon is an independent GEO consultancy based in Toulouse, founded by Reda Slimani and deliberately kept small. Its method, called V·I·G·I·E, runs in five steps over twelve months, with no commitment and a monthly PDF report. In the first week, the consultancy builds 8 to 12 buyer questions and records them in anonymous browsing on ChatGPT, Perplexity, Gemini and AI Overviews, with dated screenshots.
The published case, Laucked, shows Google impressions multiplied by 3.4 between April and May 2026 and citations by Perplexity and Gemini in the 04/06/2026 reading. It does not concern AI Overviews, but it is dated and presented with its limits: the consultancy points out that these indicators are neither leads nor revenue. The website only gives market price ranges.
Strengths
- Dated baseline reading that includes AI Overviews.
- Dated proof, presented with its limits.
- No minimum commitment.
Things to check
- No dedicated AI Overviews page or published AI Overviews result.
- Own prices not displayed.
Premiere.Page
Agency in Anglet founded in 2013
Premiere.Page, an agency founded in 2013 in Anglet, published on 23/07/2026, the day after the launch, an article on the arrival of AI Overviews in France, and offers GEO services from €690 excl. VAT per month, one of the lowest entry prices in the panel.
It is the only agency in the panel, apart from Astrak, to publish AI visibility data for a named client: according to the agency, baiebrassage.fr totals 44.7k impressions in Google’s AI features over three months, recorded in Search Console, with a demo video filmed from France. The period is not precisely dated and the curve starts before the French launch, which the agency attributes to citations obtained abroad.
Strengths
- Data for a named client, with a demo.
- Entry price displayed.
- Content published the day after the launch.
Things to check
- No dedicated AI Overviews offer page.
- Imprecise measurement period, to be clarified.
Cleatis
Lyon agency, dedicated AI Overviews page
Cleatis, a certified Google Partner agency based in Lyon and Brignais, relaunched in 2020 after a first company founded in 2010, has a page dedicated to « AI Overviews Google (AEO) ». The page sets out five rules for being picked up in an AI Overview, including answering in the first lines and providing verifiable elements, and measurement cross-checks Search Console impressions with manual verification. Its AI visibility audit tests 30 to 60 questions across several engines, with listed deliverables.
Its GEO agency page rules out any guarantee, stating plainly that a guaranteed position in ChatGPT or in an AI Overview does not exist. The AI Overviews page, for its part, publishes no price, no client case and no update date.
Strengths
- Offer page dedicated to AI Overviews.
- Clear method and cautious stance on guarantees.
- Clearly scoped audit.
Things to check
- No GEO or AI Overviews results published; the site’s case figures concern SEO.
- Undated page, price not displayed.
SLASHR
Lille agency, in-house tracking tool
SLASHR, a Qualiopi-certified agency in Lille, relies on an in-house tool, Janus, which tests six engines (Google AI Mode on its GEO page, Google AI Overviews on its audit page) and tracks mention rate, share of voice, cited sources and query fan-out. Its tracking explicitly separates mention rate from link rate and cited sources.
Prices are displayed: audit from €1,500 to €5,000 excl. VAT, engagements from €1,200 excl. VAT per month. The published case studies with figures, including Vestiaire Collective in the United States, are SEO cases, and the page’s introduction still presents the French rollout as a summer 2026 announcement, without the 22 July date.
Strengths
- Named proprietary tool covering Google’s engines.
- Mentions and sources tracked separately.
- Public prices.
Things to check
- List of tracked engines differs from one page to another.
- Introduction on the French launch needs updating.
Semsew
Lille-area agency, GEO and AI Overview page
Semsew, a brand of the company ReInvent based in Sainghin-en-Weppes near Lille, claims more than fifteen years of expertise and has a page on optimisation for Google AI Overview and AI engines. Its method has four workstreams, including an AI Overview audit, and the agency offers a white paper on AI Overviews in France, July 2026 edition.
The GEO case published on 22/07/2026, from 0 to 18 AI citations per month in six months across 40 queries replayed twice a month, concerns Perplexity, ChatGPT Search and Gemini, for an anonymous client. A blog article also reports appearing in AI Overviews on 34% of 80 queries as early as March 2026, before the French launch: a point to clarify. Its quote configurator shows an indicative price from €350 excl. VAT per month.
Strengths
- Offer page naming AI Overviews.
- Quantified measurement protocol on AI engines: 40 queries replayed twice a month.
- Indicative entry price displayed, the lowest in the panel.
Things to check
- AI Overviews result predating the French launch.
- Anonymous GEO case, undated period; price to be confirmed on quote.
Lemon Interactive
Lille agency since 2009, 25 experts
Lemon Interactive, based in Lezennes near Lille since 2009 with 25 experts, presents a five-step GEO offer and names its tools: Haloscan, Ahrefs, Search Console, Yourtext.guru. On 24/07/2026 it published an article on AI Overviews in France with six actions to apply, updated on 17/08/2026.
The agency claims more than 30 clients supported in AI optimisation and a « +30% share of voice at 3 months » on average, without a date or scope. Its monthly report covers ChatGPT, Gemini and Perplexity, but not AI Overviews.
Strengths
- Named tools and a structured method.
- Dated, updated AI Overviews content.
Things to check
- AI Overviews missing from the monthly report.
- Undated result figures.
Agencies we reviewed but left out
Five other agencies were reviewed closely. Darwin Agency, in Aix-en-Provence, tracks its clients’ visibility with its BrandSight tool on ChatGPT, Gemini, Claude and Mistral, but not on AI Overviews. Adimeo has a GEO page with no section on AI Overviews. Etowline, in Metz, offers a calculator of traffic lost to AI Overviews, but measures visibility on ChatGPT, Gemini and Perplexity. Enjin, in Cholet, claims a client featured in AI Overviews with +28% visibility on a page updated in December 2025, before the French launch. Axess includes AI Overviews in its protocol and displays its prices, but it is a group of 300 employees, far from the profile of the specialised agencies in this ranking.
Some twenty other agencies had, as of 22/09/2026, only a blog article on the subject, with no offer or measurement dedicated to AI Overviews.
How to choose an agency for Google AI Overviews?
Five questions are enough to sort providers. Which queries will you measure me on, and how often? Without a fixed, dated panel, no progress can be demonstrated. Do you track mentions or only citations? For a company, seeing its name recommended in the answer matters more than a link among the sources. With which tool? An unnamed « monitoring platform » cannot be checked. When are your results from? An AI Overview result from before 22 July 2026 was not measured on Google France. How much does it cost? Five agencies out of eight display a price.
Finally, be wary of any guaranteed citation: Google chooses its sources from its index, query by query, and no agency controls that choice. What we measure is detailed on our AI Overview agency page, and the wider framework on our GEO agency page.

Frequently asked questions
Which is the best AI Overview agency in France?
As of 22/09/2026, three agencies publish the most verifiable evidence on AI Overviews: Astrak (full method, positioning audit, displayed price), Stafe (monthly report including AI Overviews, detailed prices) and Vigeon (dated baseline reading including AI Overviews). The right choice depends on your size and the level of proof you require.
Should an agency track mentions or citations?
Both, but not with the same weight. A citation is a page linked among the sources; a mention is the brand name written in the answer. For a publisher, citations bring traffic. For a company, mentions matter more: they put the brand on the prospect’s shortlist.
Can a GEO agency handle AI Overviews?
Often, but not always. The levers overlap (citable content, third-party sources, structured data), but AI Overviews depend on Google’s index: a GEO agency without solid SEO foundations will struggle to get its clients named there.
How much does an AI Overview agency cost?
Of the eight agencies ranked, five display a price: Semsew from €350 excl. VAT per month (indicative), Premiere.Page from €690 excl. VAT per month, Stafe from €850 to €2,500 excl. VAT per month for tracking, Astrak from €900 per month and SLASHR from €1,200 excl. VAT per month. The others work on quotes.
Can a citation in an AI Overview be guaranteed?
No. Google selects its sources query by query, and the answer changes from one day to the next. An agency can increase the likelihood of being cited and named, and measure it, but not guarantee it.
Where do you stand in Google AI Overviews?
We record your business queries in AI Overviews, AI Mode and ChatGPT, and show you which brands Google recommends instead of you.
