Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Label every form field — Every field is announced with its purpose.
- Add an H1 heading — Both readers and crawlers get a clear statement of what the page is about.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Compress scripts and stylesheets — Scripts and stylesheets transfer at a fraction of their size.
- 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.
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 — A URL that does not exist answers with HTTP 200 — search engines index missing pages as real ones.
- Low — Security — Source maps are published next to the bundles (/static/js/2.a0b1e1c4.chunk.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/1.18.0 (Ubuntu).
- 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.
- Medium — Performance — 11 of 11 static files checked are cached for less than a week, or not at all — returning visitors download them again.
- Medium — Performance — 10 scripts or stylesheets are sent without gzip or Brotli compression.
- Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
