Detailed comparison

How the agencies differ

Capabilities and focus

The two agencies overlap across their broader search briefs, which makes a direct comparison useful. Primelis is assessed as established for AI SEO and leading for established SEO work. Its distinctive listed capabilities include Enterprise SEO, International SEO, Growth. SEO.fr is assessed as established for AI SEO and leading for SEO, with SEO, Technical SEO, Content helping to distinguish its offer. These labels compare the range and public evidence visible during the August 2026 assessment; they are not guarantees of a particular ranking, citation or commercial outcome. Buyers should ask each agency to show recent work that matches the technical environment, market and search problem in the brief.

Working model and engagement

Primelis is listed for enterprise organisations in the $$$ engagement band. SEO.fr is listed for mid-market organisations in the $$ band. The dollar symbols are relative comparison bands rather than quoted fees, and a higher band is not a quality score. Scope, senior involvement, location, contract length and implementation support can all change the real cost. Because both agencies are listed in France, buyers can concentrate on delivery model and team fit rather than comparing two entirely different market contexts. Ask both agencies to price the same written scope so that retainers, projects and optional work can be compared on a like-for-like basis.

Evidence and expected output

Leading Search List reviewed 1 public source for Primelis and 1 for SEO.fr. That evidence supports an editorial comparison, but it does not replace buyer due diligence. Primelis and SEO.fr have different stated buyer fits. Before appointing either agency, request a named delivery team, a ninety-day plan, reporting examples and two case studies that resemble your organisation. For AI SEO, ask how the agency measures visibility in Google AI Overviews, ChatGPT, Gemini and Perplexity without separating that work from technical SEO, authority and useful content. The strongest proposal should connect outputs to a commercial objective and state which recommendations the agency will implement itself.
