Starting point

Outdated WordPress website with a 6s load time, poor Google rankings, no CMS for editors and no GDPR compliance.

Solution & result

Complete rebuild in Next.js with Sanity CMS, Core Web Vitals optimization, technical SEO and GDPR-compliant hosting.

Load time reduced from 6s to 0.8s, Google page 1 ranking for 12 target keywords, organic traffic +180% in 3 months.

The problem

Outdated websites cost more than they bring in

  • Every extra second of load time costs 7% in conversions — a slow website actively loses customers
  • Google ranks slow websites lower — competitors with fast sites gain visibility at your expense
  • WordPress without professional maintenance: outdated plugins, security gaps and editors who are afraid to change content
Our answer

Modern web technology with measurable performance

  • Next.js with static generation: load times under 1 second, 95+ Lighthouse score — Google loves it
  • Headless CMS (Sanity, Contentful): editors maintain content themselves, no dependency on developers for text changes
  • GDPR-compliant hosting in Germany, cookie consent, privacy-compliant analytics — no risk of legal cease-and-desist letters

FAQ

Frequently asked questions

Everything you need to know about Web Development at a glance.

01What does a professional corporate website cost?+

A modern corporate website with CMS, SEO setup and GDPR compliance starts at a fixed price of €8,000. More complex projects with customer portals or multilingual content range from €15,000 to €40,000. Binding quote within 3 business days after a free initial consultation.

02Why Next.js instead of WordPress?+

Next.js generates static HTML pages — that makes the website 5–10x faster than WordPress and eliminates security gaps caused by PHP plugins. Editors still manage content comfortably via a headless CMS such as Sanity. For performance-critical projects, it is the superior choice.

03Can we maintain content ourselves?+

Yes, that is standard. We set up a headless CMS (Sanity or Contentful) — your editors edit text, images and page structure directly in the browser without developer skills. We train your team at handover.

04What is included in the SEO setup?+

Technical SEO: structured data (Schema.org), Open Graph, sitemap, robots.txt, canonical URLs, Core Web Vitals optimization. On-page: meta titles and descriptions for all pages, heading hierarchy, internal linking structure. No tricks — clean, sustainable visibility.

05How long does a typical website project take?+

Standard corporate website (8–15 pages, CMS, SEO): 4–6 weeks. More complex portals with a login area or multiple languages: 8–12 weeks. You see a clickable prototype before development — no surprises at launch.

06Do you also take over maintenance of existing websites?+

Yes. We offer maintenance contracts from €150/month: monthly security updates, performance monitoring, backups and up to 2 hours of content changes included. For WordPress migrations to modern Next.js, we offer package prices.
