I make sure the numbers behind your marketing are right.
Most websites lose a large part of their data before anyone sees it, so the reports everyone works from are already wrong. I find what is missing, put it back, and make the numbers match what actually happened. For webshops, agencies and marketing teams across Europe.
I'm Freek Kampen, a web analytics consultant. Twelve years of this: two of them inside Google, the rest running measurement and advertising for brands across Europe.
Dutch by birth, Barcelona by choice. I live here with my wife and our son, and I still start most days with a cortado and a spreadsheet.
You cannot make marketing decisions on data that is missing.
Each of those quietly removes a share of your data before it reaches a report. Which ones apply, and how badly, is exactly what an audit establishes. It is routinely the difference between a channel that looks unprofitable and one that pays for itself.
Indicative ranges, measured across my own client base
I get called when the numbers stop making sense and nobody can say why.
I spent two years inside Google before agency life and ten years after that running advertising and analytics for brands across Europe. I learned the difference between data that looks important and data a marketing director can act on by Tuesday. Most of what I do is close that gap.
Today I run New North Digital — a small Dutch consultancy — from Barcelona, where the cortados are better and the time zone still works for clients in Amsterdam. I like to build tools that make life for data-driven marketers easier.
I work best with marketing teams who already have ambition and budget but lack measurement they can trust. If that's you, the contact form below is the right place to start.

Don't take my word for it.
I had a great experience working with New North Digital on a Business Intelligence project to develop a measurement plan for a server-side tracking implementation on Buienalarm, our weather platform (both app and web). I would definitely recommend New North Digital as a reliable and knowledgeable partner for digital analytics and measurement strategy.
We have been struggling with the problem of conversions not being assigned correctly in Google Analytics for a long time. We have been helped perfectly to solve this problem. Special thanks to Freek!
Freek helped us fantastically with our Google Analytics and tracking to gain better insight into our data. He responds quickly, thinks along and makes sure that everything runs smoothly. His help is super valuable! I would definitely recommend Freek to anyone looking for expertise in this area.
After months of frustration with a persistent tracking problem — five different agencies couldn't solve it — we contacted Freek from New North Digital. He quickly resolved what others had deemed impossible. Clear communication, in-depth expertise, and above all: results. Highly recommended for anyone with complex tracking or analytics issues.
