Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Add the <!DOCTYPE html> declaration — Browsers switch from quirks mode to standards mode — the layout stops drifting between them.
- 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.
- 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.
What the site checks found
- Medium — SEO — Both www.z4.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- 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.
- Medium — Performance — 13 of 13 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.
- Low — Privacy — The site loads Yandex Metrica with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
