The ENBRU system

Every page, built and checked the same way.

We don't build pages by hand in a page builder. Our own production system turns content into a finished static website and applies every standard below automatically — on every page, for every client.

How a page is made

From content to a finished site, in five steps.

  1. Content and structure

    Your texts, services, contact details and photos are entered once as structured data. The system generates every page from that single source, so information is never out of sync between pages.

  2. Security scan

    The system scans the site for every outside resource it actually uses and writes a Content Security Policy made for exactly that site, plus a full set of security headers.

  3. Pre-flight checks

    Before building, it checks that every linked file exists, that images are in modern formats, that there is no unused CSS and that all text is correctly encoded. Every problem is reported and fixed before the build.

  4. Build

    HTML, CSS and JavaScript are minified, structured data and HTML are validated, images are converted to WebP in four widths and the sitemap is updated with the date of every change.

  5. Handover

    The finished site is a folder of plain files. It runs on any server, with no database and no software to install.

Standards

What every ENBRU page includes.

Not a checklist we try to remember — rules the system applies and checks for us.

Performance

  • Static HTML, no database, no server-side processing
  • Minified HTML, CSS and JavaScript
  • WebP images in 480, 768, 1200 and 1920 px widths
  • Responsive srcset, so phones load small images
  • Compression and long-term browser caching
  • Built to score 90–100 in Google Lighthouse

Security

  • Content Security Policy written for each site
  • HTTPS enforced with Strict-Transport-Security
  • Clickjacking and content-type sniffing blocked
  • Referrer and permissions policies
  • Known scanner bots and sensitive file types blocked
  • Email and phone assembled only on click, hidden from spam bots

Search engines

  • Unique title and description on every page
  • Structured data (JSON-LD): business, services, offers, FAQ, breadcrumbs
  • Structured data validated at every build
  • sitemap.xml with real change dates, robots.txt
  • Canonical addresses and one preferred domain version
  • llms.txt, so AI assistants describe the business correctly

Code quality

  • HTML validated against W3C standards
  • No broken internal links or missing files

All of this, on your page.

Every standard above is part of every page we build — not an extra you pay for.
