Priority fixes for eurostar.com
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.
54% of Trains & Public Transport peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · 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.
28% of Trains & Public Transport peers do this.
Priority 3 · Harden
DNSSEC signed
Observed: No DS record was found for eurostar.com 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.
On Amazon Route 53: Enable DNSSEC signing for the hosted zone and establish the chain of trust at the registrar.
13% of Trains & Public Transport peers do this.
