What Dr Urls found on spinnwerk.at

From the audit of their public home page on 21/10/2026, worst first. Each links to what it means and how it is fixed.

• medium
  Cache-Control header missing

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

• 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
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• 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.

• low
  Excessive inline CSS

  Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.

• low
  Excessive inline JavaScript

  Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.

• low
  JavaScript files are not minified

  JavaScript is the most expensive resource type per byte because it must be downloaded, parsed, compiled, and executed.

• low
  Link is named for screen readers but has no anchor text

  Nothing is broken for users.

• low
  WebSite schema markup missing

  Google reads WebSite structured data on the home page when choosing the site name it shows above your results.
