Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Let the viewport be zoomed — Anyone who needs larger text can zoom the page.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- 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 — 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 — Security — The home page is served with Access-Control-Allow-Origin: * — scripts on any other site can read it.
- 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 — SEO — Sitemap URLs answering with an error: 3 of 3 checked — the sitemap is sending crawlers at pages that are gone.
- High — Links — Internal links leading to an error page: 10 of 10 checked.
