What Dr Urls found on bright.swiss

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.

• 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.

• medium
  Image file too large (>500 KB)

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

• 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.

• 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
  ETag header missing on resources

  Without ETags, browsers cannot efficiently validate whether cached resources have changed.

• low
  Excessive DOM nesting depth

  Deeply nested DOM trees increase the complexity of CSS selector matching and layout calculations.

• 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
  H1 heading is too long

  A concise H1 provides a clear, focused signal about the page's primary topic.

• low
  Iframe missing title attribute

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

• low
  Images not using modern format

  WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.
