Guillaume Bourdon
Founder of Beeleven, a GEO agency in Paris, and creator of Detekia.
Background
Guillaume Bourdon has 15 years of experience in digital marketing, growth and SEO.
He founded Beeleven, a French agency specialized in GEO (Generative Engine Optimization), because brands had no way of knowing what generative AI engines say about them. Beeleven measures what ChatGPT, Gemini, Perplexity and Claude answer on an industry's queries, then helps brands get cited.
He designed Detekia, the free GEO score that evaluates whether a page is ready to be cited by AI engines, with a deterministic and public method. Beeleven runs AI visibility audits for brands in every sector, from SMEs to large groups.
Topics
- GEO and AI search optimization
- AI visibility audits
- Citability and content structure
- Structured data and AI crawler access
- Measuring visibility against competitors
