Priority fixes for tinkercad.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.
57% of Design & Content Creation 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: The homepage response did not include a Strict-Transport-Security header.
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 Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.
37% of Design & Content Creation peers do this.
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for tinkercad.com was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
41% of Design & Content Creation peers do this.
Priority 4 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
80% of Design & Content Creation peers do this.
