What Dr Urls found on denniszijlstra.com

From the audit of their public home page on 12/11/2026, worst first. Each links to what it means and how it is fixed.

• high
  Content wider than viewport on mobile

  Horizontal scrolling on mobile is one of the most common mobile usability failures flagged by Google's Mobile-Friendly Test and Google Search Console.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Empty heading tag found

  Empty headings waste an opportunity to provide keyword signals and structural context.

• medium
  Font size too small for mobile

  Small text forces mobile users to pinch-to-zoom to read content, creating a poor experience.

• 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 empty anchor text

  Anchor text is one of the strongest signals search engines use to understand the content of the linked page.

• medium
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• medium
  Tap targets too small or too close together

  Small or crowded tap targets cause accidental taps, frustrating mobile users and increasing bounce rates.

• medium
  Touch targets too small

  WCAG 2.5.8 (Target Size) recommends a minimum target size of 44x44px.

• low
  Below-the-fold images not lazy loaded

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

• 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.
