What Dr Urls found on sibseo.be
From the audit of their public home page on 25/10/2026, worst first. Each links to what it means and how it is fixed.
- highTime to First Byte (TTFB) is slow
TTFB directly impacts all subsequent loading metrics.
- mediumCache-Control header missing
Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.
- lowETag header missing on resources
Without ETags, browsers cannot efficiently validate whether cached resources have changed.
- lowExcessive inline CSS
Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.
- lowKey resources not preloaded
Without preloading, the browser discovers critical resources late in the parsing process, delaying their download.
- lowTitle tag is too long
Truncated titles hide important information and can reduce click-through rates.
