Born in Cartagena in 1972, Sico balances SEO with his other great passion: surfing. He lives in a small village in Galicia, where he swears many of his best strategies come to him in the water at dawn. He also plays the drums and firmly believes that work-life balance is what sustains a long career in an industry that's constantly changing.
