Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Declare the page language on the <html> element — Screen readers pick the right pronunciation and translation tools work.
- Add the responsive viewport meta tag — The layout adapts to phones instead of being zoomed out.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Add alt text to the images that are missing it — Search engines can index the images and screen-reader users learn what they show.
- Write meta descriptions for the pages without one — Google stops inventing snippets and shows the copy you wrote.
- Update the copyright year — The footer stops telling everyone the site was abandoned.
What the site checks found
- Low — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- 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.
- 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 compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Medium — Images — Images that do not load: 1 of 8 checked — the pages show a broken picture where they were.
- Low — Infrastructure — The icon the pages declare answers HTTP 404, so tabs and bookmarks fall back to a blank page symbol.
- 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.
- Medium — Privacy — None of the scanned pages links a privacy policy (missing: privacy, imprint).
