Priority fixes for chileautos.cl

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

1. Priority 1 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 0 days, below the one-year benchmark.

   Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.

   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 Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.

   41% of Cars & Automotive peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Accelerate

   Modern image formats in use

   Observed: The homepage had 44 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.

   On Next.js: The next/image component serves optimized formats automatically.

   47% of Cars & Automotive peers do this.

   What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.

   63% of Cars & Automotive peers do this.

4. Priority 4 · Enable

   Social preview image set

   Observed: The homepage had no og:image, so shared links may show without a preview image.

   What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.

   62% of Cars & Automotive peers do this.
