Priority fixes for messenger.com

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

1. Priority 1 · Harden

   Certificate has more than 14 days left

   Observed: The certificate from DigiCert Inc was due to expire on 2026-10-30 (7 days after the check).

   Why it matters: An expired certificate makes browsers show a full-page warning. Renewing well ahead of expiry leaves time to fix a failed renewal.

   What to do: Automate renewal with ACME (for example Let's Encrypt or your CDN's managed certificates) and add a renewal review to your release calendar so any certificate inside 21 days of expiry gets attention.

   96% of Social Media & Networking peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.

2. Priority 2 · Enable

   Mobile viewport configured

   Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.

   What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.

   92% of Social Media & Networking peers do this.

3. Priority 3 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 180 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.

   38% of Social Media & Networking peers do this.

4. Priority 4 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 1 external script without async or defer.

   What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

   54% of Social Media & Networking peers do this.
