In short:
- Google’s AI Overviews answer above the classic results and cite web sources: being cited has become an acquisition channel in its own right.
- Six agencies were assessed on 22 October 2026 against eleven public, verifiable criteria: Eskimoz, datashake, Peak Ace, Semji, Noiise and Jloo.
- Eskimoz has the highest overall score (9 out of 11), ahead of datashake, Peak Ace and Semji (8 out of 11 each). A serious agency commits to method and measurement, as Google keeps control over source selection in AI Overviews.
In two years, GEO (Generative Engine Optimization) has gone from niche concept to budget line. The agency market is still young: the most advanced players publish their tools, their results and their studies. This ranking assesses six players that have built an optimisation offer for Google’s AI Overviews and generative engines, against the same criteria and based on the information they publish. The scoring grid and detailed results are in the “Ranking methodology” section.

1. Eskimoz, platform and barometers
An SEO agency with offices in Paris, London, Milan, Madrid and Düsseldorf, Eskimoz has made GEO an offer in its own right, led by Sara Chourak, GEO Manager. It offers an audit of the brand’s presence in generative engines (ChatGPT, Perplexity, AI Overviews), semantic content optimisation and citation tracking in its proprietary platform, the Eskimoz App, which includes a GEO monitoring module.
The agency has published a series of nine barometers on the presence of French companies in ChatGPT, Gemini and Perplexity, based on the analysis of 1,200 websites and 50,000 prompts over 60 days. It also organises its own conferences (twelve in 2025 according to its events page) and publishes client case studies.
2. datashake, published GEO results
datashake is a digital marketing group founded by two former members of Google’s European headquarters, based in Paris and New York. Its SEO and GEO offer, led by a Team Lead SEO/GEO, follows a four-step method: a visibility audit that identifies topics to cover and content likely to be picked up by AI assistants, content structured to answer the question first, technical and E-E-A-T optimisation, then ongoing management of presence in the engines.
The agency publishes case studies in which it reports results measured in generative engines: according to the agency, impressions on ChatGPT rose by 60% for Celio, and by 83% on ChatGPT and 113% on Gemini for Morning. In May 2026 it organised a conference in Paris, “From SEO to GEO: the new rules of visibility on LLMs”.
3. Tied - Peak Ace, tool-based tracking across markets
A German agency based in Berlin, Levallois-Perret and Nantes, Peak Ace presents a complete “LLMO & GEO” offer, from audit to tracking. Visibility tracking in the models relies on Peec AI, its default tool, complemented by dedicated reports on LLM traffic.
The agency publishes an “LLM Branchen Benchmark 2026”, which compares the visibility of industries in AI answers, and regularly organises its own events, the Peak Ace Digital Marketing Meetups. A relevant profile for targeting generative engines across several European markets.
3. Tied - Semji, the platform that measures AI visibility
Based in Lyon and led by its co-founder Bertrand Girin, Semji is first and foremost the publisher of a content platform for AI search and Google, which also offers support services. Its Intelligence Hub module tracks brand visibility across six engines (mention rate, citation rate, position), and a free GEO audit is available on its website.
Semji publishes quantified case studies (Groupe SEB, Point-P, Macif), a study on how SEO and content professionals use AI, and organises SEO Square every year, whose eleventh edition took place online on 13 and 14 October 2026. An approach suited to organisations that produce a lot of content.
5. Noiise, the Acoustiik tool
With seven offices in France, including Lyon and Paris, Noiise combines SEO and GEO in a single engagement. Its GEO offer includes an AI visibility audit, support and an in-house tracking tool, Acoustiik, which centralises the brand’s mentions and citations in AI engines along with the associated sentiment.
The agency has published a white paper, “Exclusive study: who really influences AI answers?”, and client case studies in organic search (Huttopia, Coudre.shop, Fortify).
6. Jloo, the GEO audit from Nantes
An SEO and GEO agency in Nantes that reports more than 800 clients and more than 20 SEO experts, Jloo offers a GEO audit dedicated to presence in generative engines. It publishes quantified SEO case studies, such as Kodak (organic traffic multiplied by ten in eight months) or 1001lits, and has a 4.7 out of 5 rating on Trustpilot. A progressive approach, suited to companies discovering the subject.
How AI Overviews pick their sources
Understanding the selection criteria helps evaluate an agency’s pitch:
- Domain authority: sites recognized in their field are overrepresented
- Extractable structure: explicit headings, lists, tables, direct answers at the top of sections
- Structured data: Schema.org markup makes information extraction reliable
- Freshness: up-to-date content dominates on evolving topics
- Factual accuracy: sourced figures and verifiable citations
Our detailed analysis of the phenomenon is in AI Overviews: how brands get cited.
Points to check before signing
- GEO case studies with AI visibility measurements
- A pitch that treats AI Overviews as a lever in its own right, beyond classic SEO
- A citation monitoring tool for generative engines
- Commitments focused on method and measurement: Google alone controls answer generation
Ranking methodology
Each agency is assessed against the same eleven criteria, based on public information about it (its official website, its offer, events and resources pages, the trade press) and on reviews published on Google and Trustpilot, collected on 22 October 2026. The first three criteria are common to all Journal Marketing agency rankings; the other eight are chosen for this ranking, including the last four, specific to GEO.
Scoring grid. Each criterion is worth 1 point if it is met (Yes); all other criteria are marked N.A (not applicable, as the data was not found by the editorial team) and are worth 0 points. All criteria have the same weight, 1/11 of the overall score each. The position follows from the overall score. In case of a tie, the player benefiting from a sponsored feature, indicated in the article, comes first and holds its own rank alone; then the player with more points on the GEO criteria, then alphabetical order. Among the other players, two players with the same overall score and the same points on the GEO criteria are ranked as tied at the same rank, and this is shown next to their rank.
| Criterion | What earns the point |
|---|---|
| 1. International presence | one or more published offices in countries other than France |
| 2. Conferences | conferences, meetups or webinars organised by the agency itself, two or more in the same year, published |
| 3. Expertise lead | a lead of the SEO or GEO expertise named with a job title |
| 4. GEO offer | a published offer for visibility in generative engines |
| 5. Published prices | published fees or price benchmarks |
| 6. Case studies | published client case studies with results |
| 7. Client reviews | an average rating of 4.5 out of 5 or higher on Google or Trustpilot |
| 8. AI visibility audit | an audit of the brand’s presence in AI answers offered |
| 9. Citation tracking tool | a tool tracking citations in AI answers named in the offer (in-house or third-party) |
| 10. Quantified GEO case studies | published case studies with results measured in generative engines |
| 11. Published AI search study | a study or barometer on AI search published by the agency |

Frequently asked questions
What is the best GEO agency in 2026?
Eskimoz has the highest overall score in this 2026 ranking (9 criteria out of 11), ahead of datashake, Peak Ace and Semji (8 out of 11 each). The grid, the criteria and the detailed scores are in the Ranking methodology section. The final choice still depends on your volume, your markets and your budget.
What are Google AI Overviews?
They are the AI-generated synthetic answers Google displays above classic results. They rely on cited web sources, and their presence strongly reshapes click distribution on the results page.
Can anyone guarantee a presence in AI Overviews?
Presence depends on Google, which fully controls generation and source selection. A good agency works on what favours citation (structure, authority, structured data) and thus maximizes citation probability; a serious commitment therefore covers method and measurement.
