Priority fixes for coop.se
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 7 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.
On Cloudflare: Use Cache Rules to set edge and browser TTLs for static file paths.
59% of Food & Grocery Delivery peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Harden
HSTS kept for at least a year
Observed: Strict-Transport-Security was sent with a max-age of 30 days, below the one-year benchmark.
What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.
On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.
42% of Food & Grocery Delivery peers do this.
Priority 3 · 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.
63% of Food & Grocery Delivery peers do this.
Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for coop.se, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
On Cloudflare: Cloudflare documents which CAs its managed certificates need; include them in your CAA records.
9.7% of Food & Grocery Delivery peers do this.
