Priority fixes for icloud.com
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 1 days, 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.
35% of Cloud Storage & File Transfer peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · 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.
44% of Cloud Storage & File Transfer peers do this.
Priority 3 · 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.
5.3% of Cloud Storage & File Transfer peers do this.
Priority 4 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
17% of Cloud Storage & File Transfer peers do this.
