Junto
Junto is a Paris performance marketing agency on rue Saint-Fiacre in the 2nd arrondissement. Its site states it has worked with more than 800 companies since 2016 across SEO, paid media, CRM, data and AI search visibility.
It runs two separate AI search service lines, an AI SEO offer and a standalone AI Overview optimisation service, each with its own multi-step method covering citability audits, entity and schema design, and continuous citation monitoring through its own tracking platform. Its client roster includes named enterprise accounts across automotive, professional services and higher education.
You are a mid-size or enterprise brand wanting AI search work built on the same data platform as your existing SEO and paid media.
- Runs two distinct named AI search service pages rather than folding GEO into a generic SEO pitch
- Publishes a monthly price range for ongoing SEO work, which most of this market does not
- Built its own SEO and AI citation tracking platform rather than relying only on third-party tools
- A 46 percent traffic increase from conversational surfaces is attributed to one case study and is self-reported
- The AI Overview service is quoted on request, so the published monthly ranges cover standard SEO packages rather than AI search work
Optimize 360
Optimize 360 is a Paris search and digital performance agency on rue Daguerre in the 14th arrondissement, operating since 2012 with further offices in Lyon, Bordeaux, Lille, Rennes, Rouen, Aix-en-Provence and Geneva.
Its GEO page lays out a five-phase process from an AI presence audit through schema and trust signal implementation to monthly citation monitoring, and names eight platforms it tracks including Google AI Overviews and AI Mode, Copilot, ChatGPT, Gemini, Perplexity, Claude and Mistral AI. Naming Mistral is unusual among French agencies.
You want one agency tracking visibility across the full spread of assistants used in France, including the domestic model.
- Names Mistral AI as a tracked platform, which every other agency in this market omits
- Its GEO page sets out eight concrete levers, including Wikidata and Wikipedia development and Reddit presence, not just content edits
- Operating from the same Paris office since 2012, with seven further French and Swiss locations
- Named case study clients are mostly hospitality, real estate and finance businesses rather than large multi-market brands
- GEO pricing is described only as a monthly retainer starting from several thousand euros, with no figure published
SEO.fr
SEO.fr is a search agency in Guyancourt, in the Yvelines department of Ile-de-France, operating since 1998. Its services span SEO, GEO, paid search, combined search and experience work, web analytics and hosting.
Its GEO page sets out a six-step process running from an AI visibility audit through a brand mention strategy, citation-focused content, link building aimed at the articles assistants reference, technical work on llms.txt and schema, and ongoing tracking through its own visibility checker tool. It names five target surfaces.
You want a long-established agency with nearly three decades of search history to add a dedicated GEO workstream.
- Nearly 30 years of continuous operation, longer than any other agency in this market
- Built a named purpose-specific AI visibility checker rather than relying on generic reporting
- Its six-step GEO method is documented publicly rather than described in one marketing paragraph
- Guyancourt is roughly 20 kilometres from central Paris, further out than the others here
- No pricing, team size or named GEO client case study is published
EPIXELIC
EPIXELIC is a 14-person web agency in Maisons-Alfort, in the Val-de-Marne department bordering Paris, operating since 2004. It offers website creation, SEO, paid search and GEO.
Its site states plainly that it supports clients on SEO, Google Ads and GEO so they appear in the answers of ChatGPT, Gemini and Perplexity. The description is a single paragraph rather than a documented method, so the depth of the GEO offer is harder to verify than at the larger agencies here.
You are a smaller business near Paris wanting one small team handling a website, SEO and a first step into AI search together.
- Names the specific assistants it targets rather than referring to AI search in the abstract
- Small stable team, including staff who teach at a Paris university and an engineering school
- Real address a short distance from central Paris, useful for in-person meetings
- Advertises a first-page Google ranking as part of its offer, a claim worth pressing on since ranking outcomes are hard to write into a contract
- The GEO description is one paragraph with no named method, tracking process or GEO-specific client example, the thinnest evidence in this list
How we ranked these agencies
- Whether GEO is a named service on the agency's own site, not a blog topic
- Third-party review score on Clutch, GoodFirms or G2 where published
- Named services and a clear, public description of the offer
- Company longevity and team size
- Fit for enterprise versus small and mid-size brands
- Pricing transparency
- Evidence of real, named client work
Every agency listed is real and operating. Founding years, ratings and services come from the agency website or a third-party review platform, verified 2026-09-17. Where a figure is not published, the page says so rather than estimating.
Why work with a GEO agency in Paris
One agency here names Mistral AI as a tracked platform alongside ChatGPT, Gemini, Perplexity and Claude. Given Mistral's domestic profile, that is a genuinely relevant difference in France and nobody else in this market mentions it.
Paris agencies use the English term GEO on their French-language service pages rather than a homegrown label, so the French and English search terms reach the same pages. None of the six labels anything AEO, which is why this city has no AEO page.
Two of the six built their own AI citation tracking tools rather than reselling a third-party platform, which is unusual outside the largest markets.
Named clients skew toward large regulated and multinational accounts headquartered in the region, including a major bank, a pharmaceutical group and a utility. That reflects how much corporate head-office activity concentrates in the capital.
One agency publishes 1,335 to 2,670 euros a month for ongoing SEO packages, though its AI search work is quoted separately. Another describes GEO retainers only as starting from several thousand euros a month. The rest require a custom quote.
