I’m Matthis Duarte
Over 10 years of experience in SEO and Organic Growth, I’ve driven millions in organic revenue for international brands in some of the most competitive verticals. A recognized voice in SEO and AI search, I work across technical SEO, site migrations, international search, and AI visibility, how brands show up inside ChatGPT, Perplexity and Gemini. I’m the founder of Knownful, based in Europe and working in English, French and Spanish.
What I actually do.
I solve two problems. The first is technical SEO, the architecture, crawl budget, internal linking, and rendering issues that kill organic visibility. The second is AI brand visibility, making sure your brand shows up when LLMs answer your customers’ questions.
Technical SEO
Site migrations, log analysis, hreflang, Core Web Vitals, crawl budget. The unsexy work that moves the needle.
AI brand visibility
Tracking and improving how brands appear inside ChatGPT, Perplexity and Gemini, backed by 10,000+ brand mentions tracked every month.
Why I built Knownful.
The content problem
I got tired of SEO content that was either too basic to be useful or too theoretical to be actionable. Knownful is the site I wanted when I was starting out, deep, data-driven, practitioner-led.
The AI visibility gap
The brands that figure out AI visibility now will have a meaningful advantage in 18 months. Most are completely unprepared. I want to help ambitious teams be in the group that’s ready.
Background
French, based in Valencia. Studied geopolitics at Paris Panthéon-Sorbonne before landing in SEO, which made more sense than it sounds. Self-taught in Python, which I use daily to automate analysis and build tools.
Outside work
I play chess competitively, including international tournaments. More overlap with SEO than most expect: both reward preparation, pattern recognition, and thinking several moves ahead.
Deep preparation, pattern recognition, and thinking several moves ahead: the same instincts that win at chess are the ones I bring to search and AI visibility.
