What Dr Urls found on gilles.ch

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
  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
  Cache-Control header missing

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

• medium
  Empty heading tag found

  Empty headings waste an opportunity to provide keyword signals and structural context.

• medium
  Image file too large (>500 KB)

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

• medium
  Link has malformed or empty href

  Malformed links cannot pass link equity and waste crawl budget when search engines attempt to follow them.

• 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
  ETag header missing on resources

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

• low
  Image has empty alt attribute

  If a content-relevant image has an empty alt attribute, search engines cannot understand what the image depicts, and it will not appear in image search results.

• low
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.
