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 <!DOCTYPE html> declaration — Browsers switch from quirks mode to standards mode — the layout stops drifting between them.
- Add the responsive viewport meta tag — The layout adapts to phones instead of being zoomed out.
- Add an H1 heading — Both readers and crawlers get a clear statement of what the page is about.
- Write meta descriptions for the pages without one — Google stops inventing snippets and shows the copy you wrote.
- Turn on gzip or brotli compression for HTML — HTML transfers shrink by roughly 70%, cutting load time on every visit.
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.
- Medium — SEO — Both www.coslight.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- 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: x-powered-by: PHP/5.4.16.
- 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 — 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, terms, imprint).
