Priority fixes for purehtml5.cc
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HTTP requests move to HTTPS
Observed: A request to http://purehtml5.cc/ 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.
Priority 2 · Enable
robots.txt published
Observed: No robots.txt file was returned at the site root.
What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.
83% of Puzzles & Video Games peers do this.

Priority 3 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 4 hours, 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.
Priority 4 · 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.
