What Dr Urls found on smart-impact.ch

From the audit of their public home page on 24/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Missing landmark elements

  WCAG 1.3.1 requires that page structure is programmatically determinable.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Cache-Control header missing

  Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.

• medium
  Font size too small for mobile

  Small text forces mobile users to pinch-to-zoom to read content, creating a poor experience.

• medium
  Form inputs missing autocomplete attribute

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

• medium
  Image file too large (>500 KB)

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

• medium
  Render-blocking CSS or JavaScript

  Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.

• medium
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• low
  Data table missing caption

  Table captions help all users (including screen reader users) understand the purpose and context of the table before navigating its contents.

• low
  ETag header missing on resources

  Without ETags, browsers cannot efficiently validate whether cached resources have changed.

• low
  H1 heading is too long

  A concise H1 provides a clear, focused signal about the page's primary topic.

• low
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

And 2 more. 3 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
