Priority fixes for dieselogasolina.com

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.

   90% of Cars & Automotive peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

2. Priority 2 · 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.

   83% 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.

   41% of Cars & Automotive peers do this.

4. Priority 4 · Accelerate

   Modern image formats in use

   Observed: The homepage had 35 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.

   47% of Cars & Automotive peers do this.
