What Dr Urls found on joerg-seppel.de

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
  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
  Duplicate ID attributes found

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

• 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
  Web font uses font-display: block

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

• 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
  Excessive use of bold/strong tags

  Google considers <strong> tags as a mild emphasis signal for the bolded text.

And 7 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
