The local market
Paris supplies most of the French shortlist, while Lyon, Marseille and Montpellier add regional options. Eskimoz, Uplix and Primelis lead the 2026 order. French-language content and domestic search behaviour matter, but many larger briefs also require international SEO across Europe. The agencies below cover enterprise programs, technical SEO, eCommerce and AI-search visibility.
The service brief
Ask every shortlisted agency to show recent technical seo work that resembles your site, market and internal delivery model. Confirm which recommendations the agency will implement, which require your team and how success will be measured.
The commercial comparison
The shortlist contains 0 in $, 2 in $$, 2 in $$$. Treat the bands as a starting point for scoping, not a quality scale. Use one written brief so team seniority, included work, contract length and reporting can be compared fairly.
