What the site checks found
- Critical — SEO — robots.txt disallows crawling of the home page — search engines are shut out of the site.
- 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 — Both www.erlit.ru and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- 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 — Response headers publish exact software versions: server: nginx/1.30.6.
- Low — Security — No CAA record — any certificate authority may issue a certificate for this domain.
- Medium — Performance — 1 of 12 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 gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
- Low — Performance — 10 static files are served over HTTP/1.1 while the pages use HTTP/2.
- Low — Links — Internal links that reach their page through a redirect: 1 of 10 checked.
