Why I’m Proud of the Projects I’ve Built
— My Case Studies

Over the years, I’ve had the chance to build, grow, and optimize a wide range of digital projects – from self-built travel blog networks that generate passive income, to paid advertising campaigns that moved the needle for real businesses. Each project taught me something new, representing hours of strategy, testing, and iteration that turned into measurable results.

🎯 This section steps back to share why I do this work, what these projects mean, and where you can explore the full story behind each one. 🚀✨

Philosophy & Transparency

Why I Build Case Studies

02 Beyond Resumes

Complete Transparency

That transparency is something I care about, and it’s why I take the time to document these projects properly rather than just listing them as bullet points on a resume.

03 Continuous Growth

Honest Reflection

There’s also a personal reason: every project started as an uncertain idea. Writing case studies is my way of reflecting on what worked, what didn’t, and what I’d do differently next time to keep improving.


Expertise & Domains

What You’ll Find Across My Case Studies

The projects I’ve documented span a few different areas of digital marketing and web strategy:

02 PPC & Bidding

Paid Search & Bidding Strategy

Campaigns built around automated bidding models, budget scaling, and traffic optimization for specific client goals.

03 Expansion

Multi-Language & Multi-Market

Taking a working concept in one language or region and successfully adapting it for new markets.

04 Organic Growth

SEO & Organic Growth

Practical, hands-on search engine optimization work: from technical fundamentals to content structure and backlink strategy.

05 Agency Work

Client & Agency Work

Hands-on campaign management for businesses across different industries, each with its own goals, budget constraints, and audience.

06 Core Focus

Measurable Impact

What ties all of these together is a focus on results that can actually be measured — traffic, conversions, revenue, or return on ad spend. I’m not interested in vanity metrics; I want to know that the work I did had a real, quantifiable impact.


Featured Portfolio

A Few of the Projects I’m Most Proud Of

If you want to go deeper into any of these, each one has its own dedicated write-up.

  • 01

    One of the projects closest to my heart is the travel blog network I built from the ground up. What started as a single German-language blog turned into a whole ecosystem of city-specific and niche travel sites, translated into multiple languages and monetized through affiliate ticket sales and advertising.

  • 02
    Kiel Campaign Strategy ↗ Paid Advertising

    On the paid advertising side, I’ve worked on campaigns like the one detailed in my Kiel case study, where the focus was on structuring and scaling a local campaign to get the most out of a defined budget with high precision.

  • 03
    Learnlight Corporate Growth ↗ Specialized Niches

    My Learnlight case study covers a campaign built around a very specific audience and product — language training for businesses — where messaging and targeting precision made a real difference in performance.

  • 04
    Casinos.de Vertical ↗ Regulated Verticals

    Similarly, the casinos.de project is a good example of working in a highly competitive, tightly regulated vertical, where compliance and careful campaign structuring are just as important as creative strategy.

  • 05
    French Market Expansion ↗ Market Expansion

    For a look at how I approach entering a new geographic market, the French market case study walks through the process of adapting an existing strategy for French-speaking audiences — from language and cultural nuances to competitive differences.

  • 06
    My Magic Story ↗ Product Building

    And finally, one of the more personal projects I’ve documented is My Magic Story, which shows a different side of the kind of work I do — building something from an idea, shaping its positioning, and growing it over time.


Core Commitments

Why Case Studies Matter — Beyond the Portfolio

I think it’s worth saying this clearly: these case studies aren’t just marketing material for me. They’re a record of how I think and how I work. If you’re considering working with me, or you’re just curious about digital marketing and want to see real examples instead of theory, I’d genuinely encourage you to read through a few of them.

A few things I try to be consistent about across every case study:

02 Metrics

Real Numbers

Traffic figures, conversion improvements, ROAS, and other measurable outcomes wherever I can share them.

03 Strategy

Full Context

Explaining the market, the constraints, and the goals — focusing heavily on the overarching strategy, not just isolated tactics.

04 Growth

Lessons Learned

Because every project, successful or not, teaches something valuable worth carrying forward into future work.


Conclusion & Takeaways

Final Thoughts

Building a portfolio of case studies has been one of the more rewarding parts of my work. It forces me to slow down, reflect, and articulate what I actually did and why — which, in turn, makes me better at the next project.

02 Navigation

Explore By Interest

If you’re exploring this site, I’d recommend starting with whichever case study is closest to your own interests — content and SEO, paid advertising, market expansion, or niche industries — and going from there. I’ll keep adding to this collection as new projects reach a point where there’s a real story to tell.

03 Appreciation

What I’ve Actually Done

Thanks for taking the time to read this far. I hope these case studies give you a genuine sense of how I approach digital marketing — not just what I say I can do, but what I’ve actually done. 🚀
