Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Add the responsive viewport meta tag — The layout adapts to phones instead of being zoomed out.
- Turn on gzip or brotli compression for HTML — HTML transfers shrink by roughly 70%, cutting load time on every visit.
- 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
- Low — SEO — Pages the crawl found that the sitemap does not list: 4 of 5 — crawlers have to reach them through links alone.
- Medium — SEO — Both www.dtn.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Medium — Security — The TLS certificate expires in 21 days.
- 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.
- 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 — 10 scripts or stylesheets are sent without gzip or Brotli compression.
- Low — Links — Internal links that reach their page through a redirect: 1 of 10 checked.
- 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.
