What Dr Urls found on primeup.de

From the audit of their public home page on 06/11/2026, worst first. Each links to what it means and how it is fixed.

• high
  Multiple canonical tags found

  Multiple canonical tags with different URLs create conflicting signals that Google may resolve by ignoring all of them and choosing its own canonical.

• 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
  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
  Nested interactive elements detected

  Nested interactive elements produce unpredictable behavior across browsers and assistive technologies.

• 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.

• medium
  Too many external CSS stylesheets

  Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.

• medium
  Web font uses font-display: block

  font-display: block hides text for up to 3 seconds while the web font downloads.

• low
  Below-the-fold images not lazy loaded

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

• low
  CSS files are not minified

  Unminified CSS files are larger than necessary, increasing download time and delaying rendering.

• low
  ETag header missing on resources

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