What Dr Urls found on alter-solutions.pt

From the audit of their public home page on 27/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Missing landmark elements

  WCAG 1.3.1 requires that page structure is programmatically determinable.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• high
  Too many HTTP requests per page

  Each HTTP request incurs overhead from DNS lookup, TCP connection, TLS handshake, and server processing.

• medium
  Above-fold images not prioritized

  The Largest Contentful Paint (LCP) element is often a hero image.

• medium
  Cache-Control header missing

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

• 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
  Missing skip-to-content navigation link

  WCAG 2.4.1 requires a way to bypass blocks repeated on every page.

• medium
  Open Graph og:image tag missing

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

• low
  Below-the-fold images not lazy loaded

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

• low
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• low
  CSS files are not minified

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