Priority fixes for misskey.io

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

  1. Priority 1 · Accelerate

    Static files cached for 30 days or more

    Observed: A same-site stylesheet or script was cacheable for 7 days, short of the 30-day benchmark.

    Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.

    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.

    55% of Social Media & Networking peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

  2. Priority 2 · Harden

    HSTS kept for at least a year

    Observed: Strict-Transport-Security was sent with a max-age of 30 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.

    On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.

    38% of Social Media & Networking 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.

    64% of Social Media & Networking peers do this.

  4. Priority 4 · Accelerate

    No render-blocking scripts in <head>

    Observed: The homepage <head> loaded 1 external script without async or defer.

    What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

    54% of Social Media & Networking peers do this.
