What Dr Urls found on one-com.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.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- highPage contains no internal links
Pages without internal links prevent crawlers from discovering other content on your site and trap users with no way to continue navigating.
- 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.
- 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.
- mediumNo :focus-visible styles detected
WCAG 2.4.7 requires a visible focus indicator for all interactive elements.
- lowApple touch icon missing
The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.
- lowH1 heading is too long
A concise H1 provides a clear, focused signal about the page's primary topic.
- 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.
- lowMeta description is too long
Truncated descriptions cut off your message to potential visitors.
And 1 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
