Priority fixes for backmarket.it

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

1. Priority 1 · Accelerate

   Modern image formats in use

   Observed: The homepage had 149 images and none used WebP or AVIF.

   Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.

   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 Cloudflare: Cloudflare Polish can convert images to WebP.

   47% of E-Commerce & Marketplaces 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

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 183 days, below the one-year benchmark.

   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.

   32% of E-Commerce & Marketplaces peers do this.

3. Priority 3 · Harden

   CAA records limit who can issue certificates

   Observed: No CAA record was found for backmarket.it, so any public certificate authority may issue for it.

   What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.

   On Cloudflare: Cloudflare documents which CAs its managed certificates need; include them in your CAA records.

   16% of E-Commerce & Marketplaces peers do this.

4. Priority 4 · Harden

   DNSSEC signed

   Observed: No DS record was found for backmarket.it at its parent zone, so its DNS answers are not DNSSEC-signed.

   What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.

   On Cloudflare: Enable DNSSEC in DNS > Settings and add the DS record at the registrar.

   7.7% of E-Commerce & Marketplaces peers do this.
