Priority fixes for pantip.com

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

1. Priority 1 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 0 seconds, short of the 30-day benchmark.

   Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.

   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.

   51% of Forums & Communities peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

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 Next.js: Add the header in the headers() option of next.config.js for all routes.

   28% of Forums & Communities peers do this.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 11 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.

   On Next.js: The next/image component serves optimized formats automatically.

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.

   On Next.js: Use the next/script component with an appropriate loading strategy.
