Freelancer profile translated to English.
Back to original languageAbout Sylvain
I am a Principal SEO and AI Search Specialist at HubSpot, where I lead AEO/GEO experimentation and technical SEO strategy for microapps, blogs, and more. In short, I spend my days figuring out how to make content visible, not only on Google, but also in AI responses like ChatGPT, Perplexity, and Gemini.
On Malt, I work with SaaS and eLearning companies that need a technical audit that leads somewhere, meaning a clear action plan with measurable results, not a 40-page PDF that ends up in a drawer.
Core Web Vitals, crawlability, AEO optimization, indexing issues, schema markup: that's what I focus on. I don't do everything. However, what I do, I do at the level HubSpot expects.
The services provided are:
📋 Technical SEO audit execution
🗺️ Natural traffic growth strategy development
🤖 AI traffic experimentation and what works for you
👨💻 Technical optimizations (Core Web Vitals: LCP, CLS, INP)
✍️ Crawl budget improvement
🔗 Internal and external link optimization
🗐 Tag automation (Schema, title, H, etc...)
Specializing in SaaS, news sites, educational content, and travel/heritage/tech blogs, I also adapt very well to small business websites for which I achieve excellent results.
Feel free to contact me to discuss your project and how I can help you achieve your online visibility goals.
