Quality guardrails
Most outdated sites break in the same handful of ways. SOSEI fixes every one of them on the way through, so no rebuild goes live still carrying them.
- Invisible to AI search
- Contrast and structure that fail WCAG 2.1 AA
- No cookie consent
- Assets loaded from someone else's servers
- Nothing telling Google what the business is
Every page is built to WCAG 2.1 AA — the standard US ADA claims and the European Accessibility Act both point to — with contrast and structure enforced by the builder, not left to the design.
