What Dr Urls found on w-4.ch
From the audit of their public home page on 24/10/2026, worst first. Each links to what it means and how it is fixed.
- highCacheable response sets a cookie, so no CDN will cache it
The two headers contradict each other, and the contradiction is silent: the page looks cached, the CDN is configured, and every request still pays full origin latency.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- mediumAbove-fold images not prioritized
The Largest Contentful Paint (LCP) element is often a hero image.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- mediumEmpty heading tag found
Empty headings waste an opportunity to provide keyword signals and structural context.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- mediumFocus indicators removed or hidden
Focus indicators are essential for keyboard navigation.
- mediumImages missing width and height attributes
Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.
- mediumLink has empty anchor text
Anchor text is one of the strongest signals search engines use to understand the content of the linked page.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
