What Dr Urls found on taismo.de

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.

• high
  Insufficient color contrast ratio

  Low contrast text is difficult or impossible to read for users with low vision, color blindness, or in bright ambient lighting.

• high
  Slow server response time (TTFB > 3s)

  Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.

• high
  Structured data has validation errors

  Invalid structured data is completely ignored by search engines — it provides no benefit and the page will not be eligible for rich results.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• high
  Video without captions

  WCAG 1.2.2 requires captions for all prerecorded audio content in synchronized media.

• medium
  Button 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.

• medium
  Cache-Control header missing

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

• 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.

• medium
  Link has malformed or empty href

  Malformed links cannot pass link equity and waste crawl budget when search engines attempt to follow them.

• 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.
