Priority fixes for ziggo.nl
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 21 images and none used loading="lazy".
Why it matters: Images below the fold are only downloaded when the visitor scrolls near them, which frees bandwidth for what is visible first.
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
66% of Telecommunications & Internet peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 3 external scripts without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
37% of Telecommunications & Internet peers do this.
Guide: Control Third-Party Scripts Before They Control Your Page
Priority 3 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
13% of Telecommunications & Internet peers do this.
Priority 4 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from DigiCert Ireland Limited had a 364-day validity period, longer than the 100-day maximum that applies from March 2027.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
28% of Telecommunications & Internet peers do this.
