Priority fixes for hankyu.co.jp

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

1. Priority 1 · Accelerate

   HTML compressed

   Observed: The homepage HTML (51 KB) was delivered without gzip, Brotli or zstd compression.

   Why it matters: Compression usually shrinks HTML several times over, so the first bytes of the page arrive sooner on slow connections.

   What to do: Enable Brotli or gzip for text responses (HTML, CSS, JavaScript, JSON, SVG) at the CDN or origin.

   86% of Trains & Public Transport peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · 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.

   41% of Trains & Public Transport peers do this.

3. Priority 3 · Enable

   XML sitemap discoverable

   Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.

   What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.

   66% of Trains & Public Transport peers do this.

4. Priority 4 · Harden

   DMARC policy enforces quarantine or reject

   Observed: The DMARC policy for hankyu.co.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.

   40% of Trains & Public Transport peers do this.
