Derrik Willemsen

My name is Derrik Willemsen. Digital marketing has been part of my life for almost 15 years, spanning nearly three decades of working with the web since building my first sites in the late nineties.

Since 2011, I have operated as an independent specialist, focusing fully on web analytics and conversion rate optimization (CRO). My expertise is providing valuable customer and behavioral insights, both on-site and within different digital channels. For my work, I use various tools, including Google Analytics, Looker Studio, Tableau, VWO, Hotjar, and GetFeedback, while continually sharpening my approach with modern AI-driven analysis.

Over the years, I have worked as an independent analyst and through two digital agencies for well-known brands such as Audi, Volkswagen, Continental, Centraal Beheer, a.s.r., and the news portfolio of Wegener Media. I have also carried out assignments related to web analytics, data collection, conversion optimization, and Google Ads for various companies in the SME sector.

Whether working independently on enterprise challenges or partnering with growing businesses, the common thread remains the same: creating engagement and measurable value by applying data.
