Priority fixes for parool.nl

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

1. Priority 1 · Accelerate

   Modern image formats in use

   Observed: The homepage had 153 images and none used WebP or AVIF.

   Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   On Next.js: The next/image component serves optimized formats automatically.

   44% of News & Media peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 1 external script 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.

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

3. Priority 3 · Enable

   What to do: Point every alternate address (http, www or apex, old paths) straight to the final URL in a single redirect.

4. Priority 4 · Harden

   Certificate lifetime of 100 days or less

   Observed: The certificate from DigiCert Inc had a 198-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.

   66% of News & Media peers do this.
