What Dr Urls found on jvmimpact.ch

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.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Above-fold images not prioritized

  The Largest Contentful Paint (LCP) element is often a hero image.

• medium
  Duplicate ID attributes found

  Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.

• medium
  Form inputs missing associated labels

  Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.

• medium
  Form inputs missing autocomplete attribute

  WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.

• medium
  Icon-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.

• medium
  Image file too large (>500 KB)

  Images typically account for 50-75% of a page's total weight.

• medium
  Images missing width and height attributes

  Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.

• low
  Below-the-fold images not lazy loaded

  Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.

• low
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• low
  Duplicate heading text on same page

  Duplicate headings reduce the uniqueness and semantic clarity of the page structure.

• low
  Image has empty alt attribute

  If a content-relevant image has an empty alt attribute, search engines cannot understand what the image depicts, and it will not appear in image search results.
