What Dr Urls found on yannandco.ch
From the audit of their public home page on 22/10/2026, 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.
- mediumForm inputs missing associated labels
Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.
- mediumForm inputs missing autocomplete attribute
WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.
- 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.
- 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.
- lowApple touch icon missing
The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.
- lowBroken heading hierarchy
Heading hierarchy provides a semantic outline of the page content.
- lowETag header missing on resources
Without ETags, browsers cannot efficiently validate whether cached resources have changed.
- lowTitle tag is too long
Truncated titles hide important information and can reduce click-through rates.
