Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Send a Permissions-Policy header — Camera, microphone and geolocation stay switched off for embedded content.
- Introduce a Content-Security-Policy — Injected scripts stop being able to run.
- Point the aria-* attributes at ids that exist — The controls announce the name the markup was already trying to give them.
- Add a skip link to the main content — Keyboard users reach the content without tabbing through the whole menu.
- Add Open Graph tags (og:title, og:description, og:image) — Shared links get a proper preview card instead of a bare URL.
- Name the sitemap in robots.txt — Every crawler finds the sitemap without having to guess its path.
What the site checks found
- Low — SEO — robots.txt has no Sitemap: line — crawlers have to guess where the sitemap is.
- Low — SEO — No entry in the sitemap carries a lastmod date, so crawlers cannot tell which pages have changed since they last read them.
- Low — SEO — Pages the crawl found that the sitemap does not list: 3 of 4 — crawlers have to reach them through links alone.
- Low — Security — The home page is served with Access-Control-Allow-Origin: * — scripts on any other site can read it.
- 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.
- Medium — Performance — 2 of 6 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Low — Performance — The HTML is compressed with zstd but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Medium — Links — Internal links leading to an error page: 1 of 10 checked.
- 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.
