Priority fixes for telcel.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.

   72% of Telecommunications & Internet peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

2. Priority 2 · 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.

   54% of Telecommunications & Internet peers do this.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 64 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.

   52% of Telecommunications & Internet peers do this.

4. Priority 4 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 29 days, 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.

   41% of Telecommunications & Internet peers do this.
