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.

60% of E-Commerce & Marketplaces peers do this.
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.
70% of E-Commerce & Marketplaces peers do this.
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.
44% of E-Commerce & Marketplaces peers do this.
