Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send X-Content-Type-Options: nosniff — Browsers stop guessing content types and executing files as scripts.
- Send an X-Frame-Options header — The site cannot be framed for click-jacking.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Preconnect to the origins the page loads assets from — The DNS, TCP and TLS work for the other origins happens while the HTML is still parsing.
- Send a Permissions-Policy header — Camera, microphone and geolocation stay switched off for embedded content.
- Add rel="noopener" to target="_blank" links — External tabs can no longer reach back into the opener window.
What the site checks found
- Low — SEO — Sitemap URLs pointing at a different domain: 47 — they will be ignored.
- Low — SEO — No entry in the sitemap carries a lastmod date, so crawlers cannot tell which pages have changed since they last read them.
- Low — Performance — Redirects before the entry page is served: 2.
- Medium — Performance — 1 of 1 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- Low — Security — No CAA record — any certificate authority may issue a certificate for this domain.
- Low — Security — The zone is not signed with DNSSEC, so a forged DNS answer cannot be detected.
- Medium — Images — Images that do not load: 1 of 2 checked — the pages show a broken picture where they were.
