What Dr Urls found on webrunner.fr
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.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- 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 file too large (>500 KB)
Images typically account for 50-75% of a page's total weight.
- 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.
- 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.
- mediumWeb font uses font-display: block
font-display: block hides text for up to 3 seconds while the web font downloads.
- lowBelow-the-fold images not lazy loaded
Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.
And 14 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
