What Dr Urls found on webseitenoptimierung-hamburg.de

From the audit of their public home page on 20/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Links implemented with JavaScript only

  While Google can execute JavaScript, it does not always follow JavaScript-based navigation.

• 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
  Above-fold images not prioritized

  The Largest Contentful Paint (LCP) element is often a hero image.

• 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
  Image missing alt attribute

  Image alt text is the primary way search engines understand image content.

• 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
  Missing skip-to-content navigation link

  WCAG 2.4.1 requires a way to bypass blocks repeated on every page.

• 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
  Apple touch icon missing

  The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.

• low
  Below-the-fold images not lazy loaded

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

And 9 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
