What Dr Urls found on estreia.pt

From the audit of their public home page on 21/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Links implemented with JavaScript only

  While Google can execute JavaScript, it does not always follow JavaScript-based navigation.

• high
  Slow server response time (TTFB > 3s)

  Page speed is a confirmed Google ranking factor, and TTFB is the foundational component.

• high
  Time to First Byte (TTFB) is slow

  TTFB directly impacts all subsequent loading metrics.

• medium
  Above-fold images not prioritized

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

• medium
  Data table missing header cells

  Screen readers rely on <th> elements to announce column and row headers as users navigate table cells.

• medium
  Elements with positive tabindex

  Positive tabindex values force elements to appear first in the tab order regardless of their position in the DOM.

• 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
  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
  Thin content (too few words)

  Google's Helpful Content system explicitly targets thin, low-value pages.

• low
  ETag header missing on resources

  Without ETags, browsers cannot efficiently validate whether cached resources have changed.

• low
  Excessive inline JavaScript

  Inline JavaScript cannot be cached by the browser and must be parsed and executed every time the page loads.
