Quick Wins

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

Declare the page language on the <html> element — Screen readers pick the right pronunciation and translation tools work.
Set width=device-width in the viewport meta tag — Phones lay the page out at their own width instead of shrinking a desktop one.
Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
Write meta descriptions for the pages without one — Google stops inventing snippets and shows the copy you wrote.
Replace the legacy doctype with <!DOCTYPE html> — The page renders in standards mode in every browser.
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 — Sitemap URLs answering with an error: 5 of 5 checked — the sitemap is sending crawlers at pages that are gone.
High — Security — http:// does not redirect to https:// — the plain-text address stays reachable.
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/1.30.4, x-powered-by: PHP/5.6.40.
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 — 18 of 18 static files checked are cached for less than a week, or not at all — returning visitors download them again.
Medium — Performance — 9 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.
Medium — Links — Internal links leading to an error page: 1 of 10 checked.
