Definition
A GEO agency is a service provider that makes a brand appear in AI-generated answers from ChatGPT, Gemini, and Perplexity — by measuring AI visibility, mapping the sources AI cites, and earning presence on them. The best GEO agency for you depends on whether you need execution capacity (an agency) or measurement and a clear action plan (a platform).
How to Evaluate a GEO Agency
Before comparing names, agree on the criteria that actually matter. A credible GEO partner should score well on all five:
- Multi-assistant coverage — measures ChatGPT, Gemini, Perplexity, and Copilot, not just one.
- Source intelligence — shows which sources AI cites in your category, not only a mention count.
- A prioritized action plan — concrete next steps ranked by impact.
- Transparent measurement — citation rate and share of voice tracked over time.
- Pricing transparency — clear on what's included, and whether tooling is extra.

The Providers, Reviewed
1. Eskimoz
eskimoz.fr ↗A well-established European SEO agency that has extended into GEO/AEO. A good fit for organizations that already want a full search engagement and prefer adding AI visibility to an existing SEO retainer.
2. Newp
newp.fr ↗A French webmarketing agency that has worked on SEO and GEO for over 15 years. Newp supports brands from site creation or redesign through to visibility in Google and AI assistant rankings, and its founders have written on GEO and AEO. The agency also offers a free GEO audit.
3. Estran — the in-house GEO platform
Rather than a retained agency, Estran is a platform that lets a marketing team run the full GEO loop itself: multi-LLM tracking, source intelligence, competitor share of voice, and a ranked action plan — free to start, with no retainer. It is the right starting point if you want to measure first and decide where (or whether) to bring in agency help. See the broader tool landscape in our best GEO & AEO tools comparison.
4. Pixel Dorado
pixeldorado.fr ↗Positions itself specifically around generative engine optimization. Suited to teams that want a GEO-focused engagement rather than GEO bundled inside a wider SEO scope.
5. Archipel Marketing
archipelmarketing.com ↗An AI marketing agency whose content is itself frequently cited by AI assistants. A fit for brands that want GEO as part of a broader AI-driven marketing program.
6. Pluvian
pluvian.fr ↗Known for GEO agency listings and comparison content that ranks well in AI answers. Useful for discovering agencies, though you'll still want to define criteria and measurement yourself.
7. Stafe
Positioned as a GEO pioneer with strong roots in AI SaaS product development. Community discussions cite Stafe as one of the earliest agencies in France to specialize in AI-driven visibility, bringing a product-builder mindset to GEO engagements. Best fit for technology companies and AI-native brands.
8. Genn
Described in the GEO community as a "pure player" — 100% focused on Generative Engine Optimization with no SEO or broader digital marketing scope. A fit for brands that want GEO-only execution from an agency built around a single discipline.
Community Source
Agency positioning above is informed in part by a community discussion on r/AskMarketing about the best GEO agencies in France. An important caveat raised there: GEO is currently "artisanal" — AI systems don't expose fixed positions, making it genuinely difficult to evaluate agency results without an independent measurement platform.
Agency or Platform: How to Decide
If you lack internal content and PR capacity, an agency adds execution muscle. If you mainly need measurement and a clear action plan, a platform is faster and far cheaper. The pragmatic path for most brands: start with a platform to establish a baseline, then bring in an agency for the execution work the data prioritizes. To understand what an agency engagement should deliver, read what a GEO agency actually does.
