What Dr Urls found on sedigital.es

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.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• 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
  Open Graph og:image tag missing

  Social media posts with images receive significantly more engagement than text-only posts.

• 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
  Apple touch icon missing

  The apple-touch-icon provides a branded icon when users bookmark your site on iOS devices.

• low
  Below-the-fold images not lazy loaded

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

• 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
  Link is named for screen readers but has no anchor text

  Nothing is broken for users.

• low
  Social media preview is incomplete

  Incomplete social previews reduce the visual appeal and click-through rate of shared links.
