About Melanie

I make marketing success measurable.
Strategic web tracking and clear data for informed decisions in the SME sector.

I help small and medium-sized companies to open the black box of their online marketing. Instead of controlling budgets based on gut feeling, I create the technical and strategic foundation for reliable decisions.

My focus is on well-thought-out tracking architectures that deliver clean and reliable data along the entire customer journey – DSGVO-compliant and future-proof.

With over 7 years of experience in performance marketing, I combine technical tracking know-how with a clear understanding of marketing goals. I know which data is truly relevant – and how it needs to be used to manage campaigns profitably.
I work at the interface of marketing, IT, and controlling and translate requirements into functioning tracking solutions.

Key Areas:

Tracking Architecture:Conception and implementation of scalable setups (incl. server-side and cross-domain tracking)
Measurement Plans:Definition of relevant KPIs and clean conversion funnels
Data Quality:Analysis of existing setups and resolution of tracking problems
Enablement:Empowering internal teams through structured workshops and practical training

Selected Results:

+25% online ticket sales through data-based optimization of marketing measures
