What Dr Urls found on closbrothers.pl
From the audit of their public home page on 21/10/2026, 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.
- highStructured data has validation errors
Invalid structured data is completely ignored by search engines — it provides no benefit and the page will not be eligible for rich results.
- mediumAbove-fold images not prioritized
The Largest Contentful Paint (LCP) element is often a hero image.
- mediumAnimations without prefers-reduced-motion
WCAG 2.3.3 requires that motion animation triggered by interaction can be disabled.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumFocus indicators removed or hidden
Focus indicators are essential for keyboard navigation.
- 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.
- mediumImage missing alt attribute
Image alt text is the primary way search engines understand image content.
- 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.
- mediumMissing canonical tag
Canonical tags are the strongest signal you can send to search engines about which URL should be indexed when multiple URLs serve similar content.
- mediumNo :focus-visible styles detected
WCAG 2.4.7 requires a visible focus indicator for all interactive elements.
