What Dr Urls found on agenciaseomadrid.tech

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
  Insufficient color contrast ratio

  Low contrast text is difficult or impossible to read for users with low vision, color blindness, or in bright ambient lighting.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Form inputs missing associated labels

  Unlabelled form fields are unusable for screen reader users, who represent a significant portion of potential customers.

• medium
  Form inputs missing autocomplete attribute

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

• 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.

• 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
  Below-the-fold images not lazy loaded

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

• low
  CSS files are not minified

  Unminified CSS files are larger than necessary, increasing download time and delaying rendering.
