Priority fixes for kraemer.de
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
Why it matters: HTTP/3 runs over QUIC, which copes better with lossy mobile networks and recovers faster when a connection changes.
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. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Harden
X-Content-Type-Options: nosniff
Observed: The homepage response did not include X-Content-Type-Options: nosniff.
What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.
64% of E-Commerce & Marketplaces peers do this.
Priority 3 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
60% of E-Commerce & Marketplaces peers do this.
Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for kraemer.de, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
16% of E-Commerce & Marketplaces peers do this.
