Quick Wins

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

Show a visible focus indicator — Keyboard users can see where they are on the page.
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.
Merge the SPF records into one — The SPF record starts being read instead of discarded.
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.

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 21 days.
Low — Security — No /.well-known/security.txt — anyone who finds a vulnerability has to guess where to report it.
Medium — Security — SPF records published: 2. The standard allows exactly one, and receivers discard all of them.
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 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 — Privacy — The site loads Meta Pixel with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
Medium — Privacy — None of the scanned pages links a privacy policy (missing: privacy, terms, imprint).
