Priority fixes for seiska.fi

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

1. 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.

   87% of News & Media peers do this. Limit: Only the standard location was requested, once, at the time of the check.

2. Priority 2 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 0 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.

   35% of News & Media peers do this.

3. Priority 3 · 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.

   On Next.js: Use the next/script component with an appropriate loading strategy.

4. Priority 4 · Harden

   Framing restricted

   Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.

   What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.

   On Cloudflare: Add the header with a response header transform rule.
