Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Declare the page language on the <html> element — Screen readers pick the right pronunciation and translation tools work.
- Set width=device-width in the viewport meta tag — Phones lay the page out at their own width instead of shrinking a desktop one.
- Add alt text to the images that are missing it — Search engines can index the images and screen-reader users learn what they show.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- 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.
What the site checks found
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- Low — Security — Response headers publish exact software versions: x-powered-by: PHP/8.1.34.
- 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 — Performance — 4 of 10 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.
