Measured, not claimed

Accessibility

A perfect score — the standard BFSG asks of you, met and measured rather than promised.

SEO

Semantic markup, clean structure and fast pages: the technical base ranking depends on.

Layout shift

Nothing jumps around as the page loads. Google calls anything under 0.1 "good".

Google Lighthouse 12.8.2, mobile profile, run against fiberseats.de on 10 July 2026. Run it yourself — we publish the site so you can.

Under the hood

Development that removes the risk

Everything below is standard on every Chris Katzer build — no upsell, no surprise invoice.

Core Web Vitals

Optimised assets, lazy loading and clean code so Google and your visitors love it.

Mobile

Mobile-first

Designed and tested on real devices — most of your customers arrive on a phone.

BFSG & DSGVO

Accessible and privacy-compliant by default, so you're covered under 2025+ German law.

A clean content system — or we handle every change for you. No code, ever.

Integrations

Booking, shop, CRM

Reservations, payments, forms and tools wired in cleanly and kept working.

Built to rank

Semantic markup, fast pages and structured data — the technical base SEO needs.

Locked down

SSL, backups, monitoring and updates handled — your site just stays up.

How we build

From brief to live in weeks

A calm, transparent process — you always know what's happening and what's next.

01

Structure

We map the pages, content and goals so the build is aimed at conversions from day one, not decoration.

02

Build & test

Hand-coded, benchmarked against Core Web Vitals and tested on real devices before anything goes live.

03

Launch & maintain

We ship it, monitor it, and keep it fast and compliant every month — updates included, no per-change fees.

Your current site costs you customers.
