Priority fixes for keiba.jp

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   HTTP/2 negotiated

   Observed: The TLS handshake selected http/1.1 instead of HTTP/2.

   Why it matters: HTTP/2 sends many files over one connection, which speeds up pages with lots of images, styles and scripts.

   What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.

   91% of Sports Broadcast & Fantasy Games peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

2. Priority 2 · Harden

   TLS 1.3 negotiated

   Observed: The TLS connection negotiated TLSv1.2.

   What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.

   90% of Sports Broadcast & Fantasy Games peers do this.

3. Priority 3 · Enable

   Meta description written

   Observed: The homepage had no meta description.

   What to do: Write a short, specific description of the page for people, not a list of keywords.

   91% of Sports Broadcast & Fantasy Games peers do this.

4. Priority 4 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   27% of Sports Broadcast & Fantasy Games peers do this.
