About Daniel

🚀 Want more qualified leads, a compelling website, and predictable customer acquisition?

I support startups and growth-oriented companies in specifically improving their online presence – with professional web design, search engine optimized content, and data-driven marketing strategy. My focus is on clear communication, strong brand impact, and measurable results.

As a performance marketer & web designer (WordPress) with a focus on conversion optimization, I help companies turn online visitors into paying customers – efficiently, thoughtfully, and without detours.

📈 Typical Projects:
– Building & optimizing WordPress websites
– SEO strategies including keyword research, structure & content
– Google Ads (Search Network) with conversion tracking & manual conversion value for more realistic control

🔍 What sets me apart:
I think entrepreneurially, work analytically, and deliver plain text instead of buzzwords. My claim: Results that pay off – not just look good.

    I help startups scale faster – with clear positioning, scalable marketing systems, and websites that function like a sales funnel.

    I identify growth levers in product, funnel, and communication and optimize for asymmetric ROI: Less input, more output.

    🔍 I eliminate bottlenecks,
    ⚙️ systematize lead generation,
    📈 and build digital assets that don't just look good but bring in customers.

    My goal isn't pretty design – my goal is: Growth Infrastructure.
    I think in terms of CAC, LTV, scalability, and Product-Market-Message Fit.
