Priority fixes for aftonbladet.se
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
Why it matters: When your link is shared in chat apps and social networks, the preview image is what people see first.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
71% of News & Media peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
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.
66% of News & Media peers do this.
Priority 3 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for aftonbladet.se, 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.
13% of News & Media peers do this.
Priority 4 · Harden
DNSSEC signed
Observed: No DS record was found for aftonbladet.se 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.
6.1% of News & Media peers do this.
