What Dr Urls found on zichtbarewebsite.be

From the audit of their public home page on 24/10/2026, worst first. Each links to what it means and how it is fixed.

• 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
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• 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.

• 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
  Key resources not preloaded

  Without preloading, the browser discovers critical resources late in the parsing process, delaying their download.

• low
  Missing preconnect hints for critical origins

  Each new origin connection requires DNS resolution, TCP handshake, and TLS negotiation, adding 100-300ms of latency.
