Priority fixes for chess.com

Ordered by impact and by how common each practice is among peers.

  1. Priority 1 · Harden

    HTTP requests move to HTTPS

    Observed: A request to http://www.chess.com/ was not redirected to HTTPS.

    Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.

    What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.

    On Cloudflare: Turn on Always Use HTTPS under SSL/TLS > Edge Certificates.

    89% of Puzzles & Video Games peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.

  2. Priority 2 · Accelerate

    Static files cached for 30 days or more

    Observed: A same-site stylesheet or script was cacheable for 28 days, short of the 30-day benchmark.

    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.

    44% of Puzzles & Video Games peers do this.

  3. Priority 3 · Enable

    XML sitemap discoverable

    Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.

    What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.

    60% of Puzzles & Video Games peers do this.

  4. Priority 4 · Harden

    CAA records limit who can issue certificates

    Observed: No CAA record was found for chess.com, 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.

    5.6% of Puzzles & Video Games peers do this.
