Priority fixes for gsfcarparts.com
Ordered by impact and by how common each practice is among peers.
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.
90% of Cars & Automotive peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · 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.
45% of Cars & Automotive peers do this.
Guide: Control Third-Party Scripts Before They Control Your Page
Priority 3 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
30% of Cars & Automotive peers do this.
Priority 4 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
On Cloudflare: Cloudflare Security Center can serve a security.txt file for the zone.
8.9% of Cars & Automotive peers do this.
