Our certifications, our conferences, our awards
SEO is not a regulated profession: anyone can call themselves an expert. We take the exams that exist, we get on stage in front of our peers, and we are ambassadors for the tools we use every day. Here is the proof, and where to verify it.
Skills approved by a jury
Two exams issued by the French professional search federation. The only ones that are authoritative in the profession.
The highest level issued by the federation. The test: three hours of a complete audit of a real site, followed by an oral defense before a panel of peers that delves into every recommendation. Since 2026, the audit has included a GEO component, and the panel questions candidates about generative engines.
The exam that validates the mastery of the fundamentals and advanced techniques of search engine optimization. A written test graded by the federation, recommended as a prerequisite before taking the CESEO.
Official Google certification in audience measurement: property setup, explorations, and conversion attribution. It is what ensures that the numbers in our reports are read correctly before drawing up a strategy.
Official Google certification in paid search. We don't sell SEA campaigns, but understanding how auctions and ads work on a SERP changes the way you approach the organic part right below it.
The journey
Eight years of fieldwork, and the certifications earned along the way.
Email Marketing Certification
Issued by Digital Certification Agency, back when Leo worked in acquisition in the broad sense.
Google Analytics Individual Qualification
Official Google Analytics Certification, ID 9562404.
QASEO then CESEO
The two FePSeM qualifications, obtained in the order recommended by the federation.
Member of FePSeM
Astrak adheres to Federation of Search Marketing Professionals (formerly SEO Federation). Specifically: a signed code of ethics, a public directory where you can verify our membership, and peers who can be contacted in the event of a dispute. This is not a logo that you can buy.
Distinguished by those who make the tools
Ahrefs Ambassador
Léo Poitevin is one of the Ahrefs ambassadors. The program recognizes practitioners known for their advanced use of the tool and their contribution to the SEO community: you cannot apply, you are selected. Ahrefs then dedicated an article from his official blog to our method.
What others say
Mentions that we didn't write ourselves.

What we commits in writing
Enforceable commitments are often worth more than a badge.
No markup on link building
Netlinking budgets are passed on at cost. Our compensation is for consulting, strategy, and execution—never on a hidden commission on links.
Signed code of ethics
Our membership in the FePSeM commits us to enforceable professional rules, and our name appears in the federation's public directory.
Data coming from Google
Our clients have an in-house dashboard connected directly to Search Console and Google Analytics. The reporting figures do not go through us.
Clear contractual framework
Standard contract, non-disclosure agreement upon request, GDPR compliance on the processing of your analytics data.
The rest is elsewhere on the site
