Priority fixes for chess-samara.ru
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
Why it matters: A canonical link tells search engines which URL to show when the same page is reachable at several addresses.
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. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.chess-samara.ru.
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.
21% of Puzzles & Video Games peers do this.
Priority 3 · 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.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
41% of Puzzles & Video Games peers do this.
Priority 4 · 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.
On Cloudflare: Add the header with a response header transform rule.
31% of Puzzles & Video Games peers do this.
