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.
Common issues this tool detects
Browsers block access to sites with expired SSL certificates.
Loading HTTP resources on HTTPS pages triggers warnings.
Certificate must match the exact domain or use wildcards.
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.
