From the audit of their public home page on 25/10/2026, worst first. Each links to what it means and how it is fixed.

• medium
  Excessive DOM size

  A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.

• 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
  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
  Stylesheets loaded in body

  Stylesheets in the body block rendering of subsequent content and can cause visible layout shifts as styles are applied incrementally.

• 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
  Duplicate heading text on same page

  Duplicate headings reduce the uniqueness and semantic clarity of the page structure.

• 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.
