What Dr Urls found on kloos.at
From the audit of their public home page on 25/10/2026, worst first. Each links to what it means and how it is fixed.
- highContent wider than viewport on mobile
Horizontal scrolling on mobile is one of the most common mobile usability failures flagged by Google's Mobile-Friendly Test and Google Search Console.
- 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.
- mediumAbove-fold images not prioritized
The Largest Contentful Paint (LCP) element is often a hero image.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- 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.
- mediumOpen Graph og:image tag missing
Social media posts with images receive significantly more engagement than text-only posts.
- mediumScripts without async or defer
Synchronous scripts halt HTML parsing while the browser downloads and executes them.
- mediumStylesheets loaded in body
Stylesheets in the body block rendering of subsequent content and can cause visible layout shifts as styles are applied incrementally.
