Byteweb builds marketing sites, landing pages and e-commerce storefronts for DACH and EU clients — focused sites in about a week, richer e-commerce rebuilds in 2–3 weeks. We work in Astro, Next.js, Shopify or Shopware with a headless CMS (Sanity, Storyblok, Payload) of your choice, wired up for Meta and Google ads with tracking, A/B tests and CRM sync. Multilingual (DE / EN / FR / IT) with proper hreflang and localized SEO.

Fundamentals

Web design & e-commerce that converts

A good website is more than a pretty layout: it loads fast, works on every device, is findable in search, and guides visitors toward action. We pair web design with performance and conversion engineering — marketing sites, landing pages and e-commerce stores that don't just look good, they measurably sell.

Technically we pick the right stack instead of a stock theme: Astro or Next.js for speed, Shopify or Shopware for e-commerce, a headless CMS (Sanity, Storyblok, Payload) for editing. Multilingual with proper hreflang, EU-hosted and GDPR-compliant, wired for Meta and Google ads with tracking and A/B tests — so every click has a purpose.

What you get

Truly fast

Sub-second loads on mobile, image/ font pipelines that just work. Your ads stop bleeding budget to slow pages.

A design people remember

Editorial typography, considered motion, emotional photography. Not another template.

Built to convert

Tracking, A/B tests, lead capture and CRM sync wired in. Every click has a purpose.

Multi-language ready

DE / EN / FR / IT — proper hreflang, localized URLs, localized SEO. Launch once, grow everywhere.

Use cases

What we build

From a focused landing page to a rich online store.

Marketing websites

Fast, conversion-focused company sites that build trust and generate leads.

Landing pages for ads

Focused pages for Meta and Google campaigns — tracked, A/B-tested, optimised for cost-per-lead.

E-commerce stores

Shopify or Shopware storefronts with clean checkout, payment integration and product management.

Website relaunch

Outdated, slow sites rethought — faster, sharper, higher-converting, without losing SEO.

CMS & editing

An editor-friendly headless CMS so your team maintains content instead of opening tickets.

CRO & optimisation

Ongoing conversion sprints based on real analytics — the site gets better after launch.

How we build sites

  1. 01

    Brand + message

    We clarify the offer and the voice before we touch Figma. Good sites start with sharp words.

  2. 02

    Design

    Art direction + component system. We show you the whole site, not an isolated mockup.

  3. 03

    Build

    Modern stack, fully typed, CMS of your choice. Editor-friendly, developer-friendly.

  4. 04

    Launch + iterate

    Analytics, CRO sprints, ads support. A site is a product — it gets better after launch.

Frequent questions

Do you use WordPress?

Only when it's genuinely right. We default to Astro or Next.js with a headless CMS for speed, but we happily work in Shopify, Shopware and WordPress.

Can you handle our Meta / Google ads too?

We partner with performance marketers we trust, and wire the site up so their work compounds — not leaks.

Can we edit content ourselves?

Yes. We ship with a friendly CMS (Sanity, Storyblok, Payload, Shopify) so your team can write, not ticket.

Timing?

A focused marketing site: about one week. A rich e-commerce rebuild: 2–3 weeks. We tell you honestly what's possible.

Shopify or Shopware for my store?

Shopify is fast to launch and low-maintenance — ideal for most DACH merchants. Shopware shines for complex B2B requirements and full data ownership. We recommend honestly based on your case, not on commission.

Is the website SEO- and ads-ready?

Yes. Clean technical SEO, fast load times, structured data and localized URLs come as standard — plus tracking and A/B tests so your ad budget doesn't leak to slow pages.
