(001b) — Where the market stays quiet

Others sell you 48 months.
We sell you a website.

Five things that go wrong daily at Dutch web design agencies (per Higherlevel and Trustpilot) — and how we do it differently.

01 / Contract

No 48-month lock-in.

No multi-year contract, no mandatory subscription. You pay for a website, not for the right to escape one. Maintenance is optional, cancelable per month.

× €129/mo × 48 = €6,192 → ✓ €1.995 — done.

 02 / Ownership

Your site. Literally.

Domain, code, hosting, Analytics, Search Console — everything in your name from day one. No proprietary CMS you can't leave. Switch any time, no remaining value, no cancellation fee.

× Code in agency's name → ✓ Code in your name.

 03 / Price

The quote = the invoice.

No "starting at €349" that turns into €1,800 six weeks later. One amount, one scope, one week. Mobile optimization, GDPR, SEO foundation and content migration are standard in every package.

× Hidden change orders → ✓ Fixed total price.

 04 / Reachability

Phone support after launch, 7 days a week.

Three weeks after go-live, any agency can stop answering the phone. We don't — weekends and evenings too. No maintenance contract required. Twan and Lorenzo are both reachable.

× "Open a ticket" → ✓ Lorenzo's mobile number.

 05 / Audit-before-signing

Free audit. Before you sign anything.

Within 48 hours, a full report on your current site — Lighthouse, Core Web Vitals, UX, GDPR, mobile, SEO. With an honest take on whether a rebuild makes sense at all. Sometimes we say: do this and this, you're done.

× 1h sales pitch → ✓ 48h report.

(SEO) — Not a separate service

SEO lives in every line.

Schema.org markup, semantic headings, Open Graph, sitemap, GDPR link, KvK in footer — we set this up by default on every build. We also measure it at others. Here are 6 audits of major Dutch retailers, run with our open-source tool.

What we ship by default on every build

  • Schema.org JSON-LD — LocalBusiness, ProfessionalService, Service, FAQPage. Required for rich results and LLM citations.
  • Full meta set — title, description, canonical, Open Graph (4 tags), Twitter Card, hreflang where needed.
  • Mobile-first markup — viewport, responsive images with srcset, Core Web Vitals below Google's thresholds (LCP, CLS, INP).
  • GDPR compliant — privacy page, cookie banner, KvK in footer, postal address, structured data correct.
  • Local SEO — Google Business Profile setup, areaServed schema, local keyword research per industry.
  • Security headers — HSTS, CSP, X-Frame, nosniff, Referrer-Policy. Google ranks secure sites higher.

What we ship separately (at no extra cost)

  • Sitemap.xml + robots.txt — auto-generated, submitted to Google Search Console + Bing Webmaster Tools.
  • llms.txt + llms-full.txt — structured content dump for ChatGPT, Claude, Perplexity. So you get cited instead of skipped.
  • Content cluster with pillar pages — industry and city pages that link internally for topical authority.
  • Ongoing monitoring — our CLI runs weekly on your site. Daily PageSpeed measurement in your own HQ dashboard.
  • Honest SEO report — no "€499/mo SEO packages". We measure, fix what's fixable, and write down what's still missing.

Do you only work around Mijdrecht and Utrecht?

No. We're based in Mijdrecht but work worldwide. Whether you're in Amsterdam, Antwerp, Berlin, London or New York — everything runs remote with weekly preview links, in any time zone. Within 30 km of Mijdrecht we also visit in person.

What does a full rebrand or rebuild cost?

From €1,495 fixed for a review-rebuild on your existing domain. New site from €2,495. Multi-page sites and web shops by quote. Fixed scope, fixed price, no per-hour billing surprises. Send us your current site and we'll work it out.

Which SMBs do you most like to help?

Companies with a working product but a dated site: cobblers, bakers, realtors, physiotherapists, landscapers, electricians, local service providers, trades. Solo or small team. If your business works well offline, we make sure it works online too.

Do you build web shops too?

Yes. Shopify, WooCommerce or headless. First the free check, then advice on which direction fits your product and margins.

Do you also do hosting and maintenance?

No hosting. You arrange that yourself with the provider that fits best (Mijn Domein, TransIP, Cloudflare). 7-day support we do have: reachable on weekends for your site too.
