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.
- Name the mobile menu button — Screen-reader users hear "Menu" instead of an unnamed button.
- 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.
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.
- Medium — Performance — 18 of 18 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Medium — Performance — 1 scripts or stylesheets are sent without gzip or Brotli compression.
- 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.
