Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Add the <!DOCTYPE html> declaration — Browsers switch from quirks mode to standards mode — the layout stops drifting between them.
- Stop robots.txt from disallowing the whole site — Search engines are allowed to read the site at all.
- 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.
- Set font-display: swap on the web fonts — Text is readable in a fallback face from the first paint instead of being hidden.
- Send X-Content-Type-Options: nosniff — Browsers stop guessing content types and executing files as scripts.
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.
- 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.
- High — Images — Images that do not load: 5 of 6 checked — the pages show a broken picture where they were.
- Low — Infrastructure — The icon the pages declare answers HTTP 403, so tabs and bookmarks fall back to a blank page symbol.
- Low — Security — Response headers publish exact software versions: server: nginx/1.30.6.
- Medium — Security — No SPF record — anyone can send email that claims to come from this domain.
- 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 — Links — Internal links leading to an error page: 4 of 10 checked.
