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 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.
- 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.
- Add the <!DOCTYPE html> declaration — Browsers switch from quirks mode to standards mode — the layout stops drifting between them.
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.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- Medium — Performance — 1 of 13 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Medium — Performance — 1 scripts or stylesheets are sent without gzip or Brotli compression.
- 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 — 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 — Privacy — The site loads Google Analytics, Yandex Metrica, Meta Pixel 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, terms, imprint).
