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.
- Make each language version its own canonical — Each language version stays in the index for its own language.
- 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 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 — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- Medium — SEO — No sitemap.xml found at either the conventional paths or the one robots.txt names.
- Medium — SEO — A URL that does not exist answers with HTTP 200 — search engines index missing pages as real ones.
- Medium — SEO — 6 hreflang links are not confirmed by a link back from the other language: / → /be/ (be), / → /en/ (en), /en/konf-2002/ → /konf-2002/ (ru). Google ignores one-way pairs.
- Low — SEO — 5 alternates are in a different language from the hreflang code they are listed under: / → /be/ (be), /en/konf-2002/ → /konf-2002/ (ru), /en/konf-2002/ → /be/konf-2002/ (be).
- 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 — 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.
