CEO & Digital Strategist · ZDS Digital · B2 Performance
I've spent more than 20 years in SEO and digital marketing. I started building sites when Google was not yet the centre of the world, founded B2 Performance in 2008, and since 2024 I have been leading ZDS Digital — the agency that brings together everything I learned across fifteen years of projects for a large Spanish hotel group, Mercadona, Kika-Leiner, Concept Middle East and others.
What I work on now: AI visibility. How a brand shows up in answers from ChatGPT, Claude, Gemini and Perplexity — search’s new point zero. To answer that with data rather than theory, we actively help build Runtruffle in a development partnership on behalf of PlayaMedia: a tracker that queries four AI assistants (ChatGPT, Claude, Gemini and Perplexity) and Google’s AI Overviews every day.
I write about what I see in real projects — no marketing theatre, no smoke. If something does not work, I say so. If something works, I say that too.
