Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Give every form a submit control — Visitors can actually send the form.
- Add an H1 heading — Both readers and crawlers get a clear statement of what the page is about.
- Add alt text to the images that are missing it — Search engines can index the images and screen-reader users learn what they show.
- Give every button an accessible name — Every control announces what it does instead of being read out as a button.
- 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 — 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.vsu.by and the canonical host serve the site with HTTP 200 — the whole site exists at two addresses.
- Medium — SEO — 3 hreflang links are not confirmed by a link back from the other language: / → /be/ (be-by), / → /cn/ (zh-cn), / → /en/ (en-gb). Google ignores one-way pairs.
- 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/5.6.40.
- 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 — 18 of 18 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.
