Priority fixes for webcartop.jp

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

1. Priority 1 · Enable

   Mobile viewport configured

   Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.

   Why it matters: Without it, phones render the page at desktop width and shrink it, which makes text tiny and hard to use.

   What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.

   97% of Cars & Automotive peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

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.

   91% of Cars & Automotive peers do this.

3. Priority 3 · 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.

4. Priority 4 · 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.

   On WordPress: Caching plugins or your host can set long browser cache lifetimes for theme and plugin assets.
