Priority fixes for nps.gov
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for no max-age, 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.
On Cloudflare: Use Cache Rules to set edge and browser TTLs for static file paths.
30% of Government Services peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
On Amazon CloudFront: Set frame options in a response headers policy.
68% of Government Services peers do this.
Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 5 external scripts 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.
39% of Government Services peers do this.

Priority 4 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
41% of Government Services peers do this.
