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.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Set font-display: swap on the web fonts — Text is readable in a fallback face from the first paint instead of being hidden.
- 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.
What the site checks found
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- Medium — Security — No SPF record — anyone can send email that claims to come from this domain.
- 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.
- Low — Infrastructure — The domain publishes no MX records, so it cannot receive email.
- Low — Privacy — The site loads Google Analytics, Google Tag Manager, Google Ads, 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 — SEO — The sitemap lists 1 pages that are not meant to be indexed — noindex, an error status or another canonical: /kursy-dlya-uchenikov-5-8-klassov.
