High-impact, low-effort fixes, ranked by what this scan actually found.

Name the mobile menu button — Screen-reader users hear "Menu" instead of an unnamed button.
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.
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 — No robots.txt — crawlers get no guidance and no sitemap pointer.
Medium — SEO — No sitemap.xml found at either the conventional paths or the one robots.txt names.
Medium — SEO — Both www.h3o.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.
Medium — Performance — 11 of 11 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 — Security — Source maps are published next to the bundles (/js/main.min.js.map), which hands over the unminified source and the comments in it.
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/1.20.2.
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 — Infrastructure — The icon the pages declare answers HTTP 404, so tabs and bookmarks fall back to a blank page symbol.
