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 a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Serve every asset over https:// — Browsers stop blocking assets and warning about the padlock.
- Add a twitter:card meta tag — Links shared on X get a preview card instead of a bare URL.
- 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.
What the site checks found
- Low — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- Medium — SEO — No sitemap.xml found at either the conventional paths or the one robots.txt names.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- 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 — Performance — 9 static files are served over HTTP/1.1 while the pages use HTTP/2.
- Low — Security — The Content-Security-Policy is report-only — violations are logged but nothing is blocked.
- 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.
- Low — Links — Internal links that reach their page through a redirect: 2 of 10 checked.
