What Dr Urls found on bisstek.com

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
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Cache-Control header missing

  Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.

• 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
  Form inputs missing autocomplete attribute

  WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.

• 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
  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
  Too many external CSS stylesheets

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

• low
  Below-the-fold images not lazy loaded

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