Our calculations are based on real-world data from Google, Akamai, and 100+ optimization projects
We apply proven conversion improvement rates: 7% increase per second faster load time, based on Google's extensive research and industry benchmarks.
Your traffic X improved conversion rate X average order value = potential monthly revenue increase from performance optimization.
We use conservative multipliers (50-80% of theoretical maximum) to ensure realistic projections based on actual client results.
Performance improvements compound over time through better SEO rankings, reduced bounce rates, and increased customer lifetime value.

Our calculator is based on Google's Core Web Vitals research and data from over 100 real client optimization projects. While results can vary based on your specific industry and audience, the calculations use conservative estimates from proven performance studies. Most clients see results within 10-20% of our projections.
Typical improvements we deliver include 40-60% faster load times, 50-80% better LCP scores, and 70-90% improvement in CLS. The exact improvements depend on your current site's issues, but most sites can achieve "Good" Core Web Vitals scores with proper optimization.
Most performance optimization projects take 4-8 weeks depending on complexity. This includes technical audit, implementation, testing, and monitoring setup. Simple optimizations can show results within 2 weeks, while complex e-commerce sites may take 10-12 weeks for full optimization.
Custom web applications: 10-18 weeks. SaaS platforms: 12-20 weeks. E-commerce sites: 10-16 weeks. Complete redesigns: 8-14 weeks. Every project includes detailed planning, design, development, testing, and deployment phases. I provide weekly progress updates and maintain clear milestones throughout.
Everything needed for launch: strategy sessions, user research, complete UI/UX design, frontend development, backend integration, database setup, payment processing (if needed), deployment, monitoring setup, and 30 days of post-launch support. No hidden costs or surprise fees.
Yes. I offer maintenance packages starting at €500/month including security updates, performance monitoring, content updates, and technical support. Many clients prefer quarterly maintenance sessions for larger updates and improvements.
