Priority fixes for americanmuscle.com

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

1. Priority 1 · Accelerate

   Modern image formats in use

   Observed: The homepage had 102 images and none used WebP or AVIF.

   Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.

   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 Cloudflare: Cloudflare Polish can convert images to WebP.

   47% of Cars & Automotive peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 10 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.

   45% of Cars & Automotive peers do this.

3. Priority 3 · 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 Cloudflare: Add the header with a response header transform rule.

   55% of Cars & Automotive peers do this.

4. Priority 4 · Harden

   Content Security Policy present

   Observed: The homepage response did not include a Content-Security-Policy header.

   What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

   31% of Cars & Automotive peers do this.
