    HTTPS / SSL Checker — is your site served securely?

    HTTPS — a site served over an encrypted connection with a valid SSL certificate — is the baseline for a trustworthy, modern site. This check confirms your page loads over HTTPS and that its certificate is valid. Without it, browsers warn visitors that your site is "Not Secure", search engines treat it as a negative, and any data exchanged is unencrypted.

    In short: Your page must be served over HTTPS with a valid, trusted, non-expired TLS certificate. It is the single most important trust signal — without it, browsers warn users away and engines distrust the page.

    What does the HTTPS / SSL check verify?

    It checks that your site is served securely and that its certificate is in good standing. Specifically:

    • HTTPS in use — the page loads over HTTPS, not plain HTTP.
    • Valid certificate — the SSL/TLS certificate is valid, trusted and matches the domain.
    • HTTP→HTTPS redirect — the insecure HTTP version redirects to the secure one rather than serving both.

    HTTPS with a valid certificate passes; a minor issue (such as HTTP not redirecting) is a warning; no HTTPS or an invalid certificate is a fail.

    How is it evaluated, and how is it scored?

    GEObubbly checks whether the page is served over HTTPS and whether its certificate is valid. It's a core, scored Security check that runs partially, since certificate validity is confirmed against the live connection.

    Why HTTPS matters for SEO and GEO

    HTTPS encrypts the connection between the visitor and your server using an SSL/TLS certificate, so the data exchanged can't be read or tampered with in transit. It has been a confirmed (if lightweight) Google ranking signal for years, but the bigger reasons are trust and access. Modern browsers label plain-HTTP sites as "Not Secure" in the address bar — a visible red flag that erodes confidence and deters visitors — and some browser features are restricted to secure contexts. For users, the padlock is a baseline expectation; its absence signals an untrustworthy or outdated site. Getting HTTPS right means installing a valid certificate (free options like Let's Encrypt make this easy), serving all pages over HTTPS, and redirecting the HTTP version to HTTPS so there's one secure canonical. It also pairs with avoiding mixed content — secure pages that still load insecure resources. For GEO, HTTPS is part of the baseline credibility engines expect; an insecure site is a weak candidate to be trusted and cited. It's the foundation of Security & HTML Quality.

    How this check scores
    Pass: Served over HTTPS with a valid, trusted certificate; HTTP redirects to HTTPS.
    Warning: HTTPS works, but HTTP isn't redirected, or HSTS is missing.
    Fail: Served over HTTP only, or the certificate is expired, self-signed, or hostname-mismatched.

    FAQ

    HTTPS is the secure version of HTTP: it encrypts the connection between a visitor's browser and your server using an SSL/TLS certificate, so the data exchanged can't be intercepted or altered in transit. It matters because it's a baseline of trust and security — a confirmed Google ranking signal, a requirement for the browser padlock that tells users your site is safe, and a prerequisite for some modern browser features. Without HTTPS, browsers flag your site as "Not Secure", which deters visitors. Today HTTPS is essentially mandatory for any credible site, not an optional extra.
