Why it matters: HSTS tells browsers to use only HTTPS for this site. Preload allows inclusion in browsers’ built-in HSTS lists.

We check Chromium’s built-in list. hstspreload.org checks eligibility for submission (HSTS header, redirect chain). Results may differ for domains that are preloaded but no longer meet current eligibility rules.

Negotiated (ALPN h2)

ALPN: h2

HTTP/3 (QUIC)

Not advertised

The server does not advertise HTTP/3 (QUIC) via the Alt-Svc header.

Recommendations for acerositasa.com.ar

Based on this scan, here are the 6 next steps that would most improve security and SEO for acerositasa.com.ar.

  1. Fix the SSL certificate

    High impact

    The certificate for acerositasa.com.ar is not valid. Browsers show a full-page warning for invalid certificates, which drives most visitors away immediately.

  2. Shorten the redirect chain (3 hops)

    Recommended

    Requests to acerositasa.com.ar pass through 3 redirects before reaching the final URL. Each hop adds latency and dilutes SEO signals — aim for a single 301 from HTTP to the canonical HTTPS URL.

    301 vs 302 vs 307: which to use Re-check the redirect chain

  3. Enable HSTS (Strict-Transport-Security)

    Recommended

    acerositasa.com.ar does not send the Strict-Transport-Security header. Without it, returning visitors can still be downgraded to HTTP by an attacker on the network. One header makes browsers always use HTTPS.

  4. Add 6 missing security headers

    Recommended

    acerositasa.com.ar sends 0 of 6 recommended security headers — missing: HSTS, CSP, X-Frame-Options…. Most take one line of server config and protect against clickjacking, MIME sniffing and data leaks.

  5. Consider HTTP/3

    Nice to have

    acerositasa.com.ar supports HTTP/2 but does not advertise HTTP/3 (QUIC). HTTP/3 improves performance on lossy mobile networks. If you are behind Cloudflare or a modern CDN it is usually a toggle.

    How to enable HTTP/2 and HTTP/3 Why HTTP/3 detection tools disagree

  6. Add a CAA DNS record

    Nice to have

    acerositasa.com.ar has no CAA record, so any certificate authority can issue certificates for it. A CAA record limits issuance to the CAs you actually use — a cheap defense against mis-issuance.
