What Dr Urls found on lecollectif.net
From the audit of their public home page on 23/10/2026, worst first. Each links to what it means and how it is fixed.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- mediumIcon-only button missing aria-label
Icon-only buttons are extremely common in modern UIs (hamburger menus, close buttons, search icons), but without aria-labels, they are completely opaque to screen reader users.
- 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.
- lowDuplicate heading text on same page
Duplicate headings reduce the uniqueness and semantic clarity of the page structure.
- lowETag header missing on resources
Without ETags, browsers cannot efficiently validate whether cached resources have changed.
- lowImages missing responsive srcset
Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
- lowImages not using modern format
WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.
