Priority fixes for grubiks.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.
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.
23% of Puzzles & Video Games peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · 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.
58% of Puzzles & Video Games peers do this.
Priority 3 · 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.
17% of Puzzles & Video Games peers do this.

What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
