SSL Certificate Checker

Check your website's SSL certificate — validity, expiry date, issuer, TLS protocol, and whether HTTP redirects to HTTPS.

Why SSL matters for SEO

  • —HTTPS is a confirmed Google ranking signal since 2014
  • —Chrome marks non-HTTPS sites as 'Not Secure' — destroying user trust
  • —An expired SSL certificate will block visitors with a scary warning
  • —Always redirect HTTP to HTTPS with a 301 to consolidate link equity
