About Sillas

Since 2010, I’ve been helping businesses get more out of their SEO and drive digital growth, both internationally and across Scandinavia, with a strong focus on Denmark, Sweden, and Norway.

My journey started with my own successful SEO affiliate projects, quickly leading to leadership roles as Head of SEO at some of Denmark’s biggest online platforms. Along the way, I’ve also co-founded startups, worked as an SEO specialist at a digital agency, and run my own business as an independent SEO consultant.

With experience from both sides of the table - in-house and agency - I haven’t just delivered growth and gained a solid, hands-on understanding of SEO and digital marketing across diverse markets, particularly in the Scandinavian region.
