What Dr Urls found on rexx-systems.com

From the audit of their public home page on 26/10/2026, 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
  Excessive DOM size

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

• 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.

• 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
  JavaScript files are not minified

  JavaScript is the most expensive resource type per byte because it must be downloaded, parsed, compiled, and executed.

• low
  Missing preconnect hints for critical origins

  Each new origin connection requires DNS resolution, TCP handshake, and TLS negotiation, adding 100-300ms of latency.

• low
  Too many on-page links

  PageRank is divided among all links on a page, so more links means less equity passed to each destination.
