Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Add alt text to the images that are missing it — Search engines can index the images and screen-reader users learn what they show.
- Give every button an accessible name — Every control announces what it does instead of being read out as a button.
- 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.
- Serve every asset over https:// — Browsers stop blocking assets and warning about the padlock.
What the site checks found
- High — Security — http:// does not redirect to https:// — the plain-text address stays reachable.
- Low — Security — Response headers publish exact software versions: server: nginx/1.30.6, x-powered-by: PHP/8.5.12.
- Medium — Security — No DMARC record at _dmarc — nothing tells receiving servers what to do with mail that fails the SPF check.
- 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 — 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 — Privacy — The site loads Google Analytics, Yandex Metrica with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
