Our Story

I'm Gema Calderón Sayoux, a freelance digital analytics consultant based in Barcelona. I help service businesses understand which traffic actually brings in customers, and fix what isn't being measured properly. I combine SEO, Google Ads diagnostics and GA4/Google Tag Manager tracking with Microsoft Clarity and BigQuery-powered Looker Studio reporting. My goal is simple: reliable data, clear diagnoses and practical next steps. I also collaborate with agencies on a white-label basis.
