Priority fixes for mitsubishi-motors.co.jp

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

1. Priority 1 · Harden

   HTTP requests move to HTTPS

   Observed: A request to http://www.mitsubishi-motors.co.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.

   On Cloudflare: Turn on Always Use HTTPS under SSL/TLS > Edge Certificates.

   95% of Cars & Automotive peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.

   What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.

   93% of Cars & Automotive peers do this.

3. Priority 3 · Enable

   XML sitemap discoverable

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

   83% of Cars & Automotive 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.

   On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.

   41% of Cars & Automotive peers do this.
