Priority fixes for archive.org
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://archive.org/ 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.
89% of Literary & Knowledge peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
Priority 2 · 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.
69% of Literary & Knowledge peers do this.

Priority 3 · Enable
Meta description written
Observed: The homepage had no meta description.
What to do: Write a short, specific description of the page for people, not a list of keywords.
88% of Literary & Knowledge peers do this.

Priority 4 · Harden
HSTS kept for at least a year
Observed: Strict-Transport-Security was sent with a max-age of 182 days, below the one-year benchmark.
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.
