Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- 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.
- Load the first image eagerly — The largest image starts downloading with the page instead of after it.
- Write meta descriptions for the pages without one — Google stops inventing snippets and shows the copy you wrote.
- Update the copyright year — The footer stops telling everyone the site was abandoned.
- Give every button an accessible name — Every control announces what it does instead of being read out as a button.
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 — Security — The TLS certificate expires in 15 days.
- Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
- 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.
- Low — Performance — The HTML is compressed with gzip but not with Brotli, which every current browser accepts and which is typically 15–20% smaller.
