Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Label every form field — Fields become usable with a screen reader and clickable by their label.
- Add a twitter:card meta tag — Links shared on X get a preview card instead of a bare URL.
- Give every iframe a title — Screen-reader users hear what each embedded frame contains.
- Preconnect to the origins the page loads assets from — The DNS, TCP and TLS work for the other origins happens while the HTML is still parsing.
- Add loading="lazy" to the embedded frames — Embedded players and maps load when they are scrolled to, not before the page has painted.
What the site checks found
- Low — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- Medium — SEO — Both www.cropscience.bayer.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- High — Security — http:// does not redirect to https:// — the plain-text address stays reachable.
- 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: server: nginx/1.30.6.
- 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.
