What Dr Urls found on optimazing.be

From the audit of their public home page on 22/10/2026, worst first. Each links to what it means and how it is fixed.

• 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 file too large (>500 KB)

  Images typically account for 50-75% of a page's total weight.

• 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
  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.

• medium
  User scaling disabled in viewport

  Disabling pinch-to-zoom prevents users with low vision from enlarging text and content to a readable size.

• low
  Below-the-fold images not lazy loaded

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

• 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
  Iframe missing title attribute

  Without a title, screen reader users cannot determine the purpose of the iframe without navigating into it.
