What Dr Urls found on mcsaatchi.ch

From the audit of their public home page on 22/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Missing H1 heading

  The H1 tag tells both users and search engines what the page is about.

• 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.

• medium
  Cache-Control header missing

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

• medium
  Image file too large (>500 KB)

  Images typically account for 50-75% of a page's total weight.

• medium
  Missing meta description

  While meta descriptions are not a direct ranking factor, they significantly influence click-through rates.

• 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
  Thin content (too few words)

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

• medium
  Too many external CSS stylesheets

  Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.

• low
  CSS files are not minified

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