Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Let the viewport be zoomed — Anyone who needs larger text can zoom the page.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- 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.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
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.
- Low — Performance — The HTML is sent with no Cache-Control, Expires, ETag or Last-Modified — every visit re-downloads it in full.
- 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 — 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 — Security — The zone is not signed with DNSSEC, so a forged DNS answer cannot be detected.
- High — Images — Images that do not load: 5 of 8 checked — the pages show a broken picture where they were.
- Low — Infrastructure — The icon the pages declare answers HTTP 423, so tabs and bookmarks fall back to a blank page symbol.
- High — Links — Internal links leading to an error page: 10 of 10 checked.
