Frequently Asked Questions
Is SSL/HTTPS a Google ranking factor?
Yes. Google confirmed HTTPS as a ranking signal in 2014. While it's a lightweight factor, HTTPS is essential for user trust, data security, and is required for HTTP/2, service workers, and many modern web features.
What does this SSL checker verify?
It checks certificate validity, expiration date, issuer, protocol version (TLS 1.2/1.3), cipher suites, certificate chain completeness, HSTS headers, and mixed content issues that could trigger browser warnings.
What is mixed content and why does it matter?
Mixed content occurs when an HTTPS page loads resources (images, scripts, CSS) over HTTP. Browsers may block these resources or show security warnings, breaking functionality and reducing user trust.
