Certificate Validity

Verifies if the SSL certificate is properly issued and trusted.

Expiration Date

Checks when the certificate expires and warns about upcoming renewals.

TLS Protocol

Identifies the TLS version being used for secure connections.

Why SSL Matters for SEO

HTTPS is a confirmed Google ranking signal. Sites without valid SSL certificates show security warnings that hurt user trust, increase bounce rates, and negatively impact conversions.

Expired certificate

Browsers block access to sites with expired SSL certificates.

Mixed content

Loading HTTP resources on HTTPS pages triggers warnings.

Frequently Asked Questions

How often should I check my SSL?

Set up automated monitoring, but manual checks before certificate expiry (30-60 days out) are recommended.

What TLS version should I use?

TLS 1.2 minimum, TLS 1.3 preferred. Disable TLS 1.0 and 1.1 for security.
