Priority fixes for prontotour.com

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

1. Priority 1 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   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.

   46% of Travel Bookings & Trip Planning peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · 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.

   68% of Travel Bookings & Trip Planning peers do this.

3. Priority 3 · Accelerate

   HTTP/3 advertised

   Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.

   What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

   33% of Travel Bookings & Trip Planning peers do this.

4. Priority 4 · Harden

   X-Content-Type-Options: nosniff

   Observed: The homepage response did not include X-Content-Type-Options: nosniff.

   What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.

   57% of Travel Bookings & Trip Planning peers do this.
