Priority fixes for btimes.jp
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HTTP requests move to HTTPS
Observed: A request to http://btimes.jp/ was not redirected to HTTPS.
Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.
What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.
88% of Uncategorized peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
Priority 2 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for no max-age, short of the 30-day benchmark.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
44% of Uncategorized peers do this.
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for btimes.jp 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.
39% of Uncategorized peers do this.
Priority 4 · Accelerate
Modern image formats in use
Observed: The homepage had 34 images and none used WebP or AVIF.
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.
33% of Uncategorized peers do this.
