What Dr Urls found on h2a.lu

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.

• high
  Insufficient color contrast ratio

  Low contrast text is difficult or impossible to read for users with low vision, color blindness, or in bright ambient lighting.

• high
  Multiple <title> tags found

  When multiple title tags are present, search engines must choose one, and they may not pick the one you intend.

• high
  Structured data has validation errors

  Invalid structured data is completely ignored by search engines — it provides no benefit and the page will not be eligible for rich results.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• 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
  Too many external CSS stylesheets

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

• low
  CSS files are not minified

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

• 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
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

And 6 more. 7 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
