Quality
Measured,
not claimed.
We audit every SHOPin storefront with the same public tools you'd use to check it yourself — GTmetrix for performance, WAVE for accessibility, the W3C validator for valid markup. Here are the latest results for the live demo, with links to the source reports.
- GTmetrix Grade A
- 0 accessibility errors
- WAVE AIM score 10/10
- W3C valid HTML
Performance
GTmetrix Grade A.
Server-side rendering, layered caching and image optimization are configured out of the box — so pages load fast on real-world connections, not just on paper.

Standards
Valid HTML. Zero warnings.
Markup is checked against the W3C Nu Html Checker — the same validator the standards body maintains. Every audited page parses clean: no errors, no warnings, UTF-8 throughout.

How we test
Reproducible by anyone.
Performance is measured with GTmetrix running Lighthouse 12.6.1 in Chrome from a London test server. Reports are public — open any link above and you'll see the same Grade A and Core Web Vitals.
Accessibility is evaluated with WAVE by WebAIM, and markup is validated with the W3C Nu Html Checker. Automated checks catch structural, ARIA and standards issues; we pair them with manual keyboard and screen-reader passes, because a clean automated report is a floor, not a finish line.
