UBG. Agence Digitale

What Dr Urls found on ubg.digital

From the audit of their public home page on 23/10/2026, 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
  Excessive DOM size

  A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.

• medium
  Icon-only button missing aria-label

  Icon-only buttons are extremely common in modern UIs (hamburger menus, close buttons, search icons), but without aria-labels, they are completely opaque to screen reader users.

• 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.

• 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
  Data table missing caption

  Table captions help all users (including screen reader users) understand the purpose and context of the table before navigating its contents.

• 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.
