What Dr Urls found on oneline.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.
- highToo many HTTP requests per page
Each HTTP request incurs overhead from DNS lookup, TCP connection, TLS handshake, and server processing.
- mediumButton has no accessible text
Buttons without accessible text are announced as just 'button' by screen readers, making them impossible to identify and use for visually impaired users.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- 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.
- mediumImage file too large (>500 KB)
Images typically account for 50-75% of a page's total weight.
- 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.
- 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.
- mediumToo many external CSS stylesheets
Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.
And 9 more. 6 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
