Priority fixes for autotrack.nl

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 1 external script without async or defer.

   Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.

   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.

   On Next.js: Use the next/script component with an appropriate loading strategy.

   45% of Cars & Automotive peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

2. Priority 2 · Harden

   Certificate lifetime of 100 days or less

   Observed: The certificate from Amazon had a 197-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.

   58% of Cars & Automotive peers do this.

3. 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.

   8.9% of Cars & Automotive peers do this.

4. Priority 4 · Harden

   DNSSEC signed

   Observed: No DS record was found for autotrack.nl at its parent zone, so its DNS answers are not DNSSEC-signed.

   What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.

   8.3% of Cars & Automotive peers do this.
