What Dr Urls found on top-seo.es

From the audit of their public home page on 11/11/2026, worst first. Each links to what it means and how it is fixed.

• 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
  Focus indicators removed or hidden

  Focus indicators are essential for keyboard navigation.

• medium
  No :focus-visible styles detected

  WCAG 2.4.7 requires a visible focus indicator for all interactive elements.

• medium
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• low
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• 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
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

• low
  Images not using modern format

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

• 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
  Title tag is too long

  Truncated titles hide important information and can reduce click-through rates.
