Priority fixes for fritz-berger.de

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 206 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.

   47% of E-Commerce & Marketplaces peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

   DMARC policy enforces quarantine or reject

   Observed: The DMARC policy for fritz-berger.de was p=none, which asks receivers to take no action on failing mail.

   What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.

3. Priority 3 · 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.

4. Priority 4 · Accelerate

   HTTP/3 advertised

   Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.

   What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

   47% of E-Commerce & Marketplaces peers do this.
