Priority fixes for bangumi.org
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
Why it matters: A sitemap helps search engines find new and updated pages, especially on large or frequently updated sites.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
71% of Entertainment & Video Streaming peers do this. Limit: Only the standard location was requested, once, at the time of the check.
Guide: XML Sitemap Guide: Include Only URLs You Stand Behind
Priority 2 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
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 Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.
31% of Entertainment & Video Streaming peers do this.
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.bangumi.org.
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.
31% of Entertainment & Video Streaming peers do this.
Priority 4 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 274 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
54% of Entertainment & Video Streaming peers do this.
