SSL certificate
Why it matters
An invalid, expired or mismatched SSL certificate shows a full-page browser warning, which stops almost every visitor.
How to fix it
- Renew the certificate before it expires – enable automatic renewal.
- Make sure it covers every hostname you use (with and without www).
Check it with
- SSL Certificate Checker – Check an SSL/TLS certificate’s validity, expiry date, issuer, hostnames and protocol.
Scoring: a passed check earns its full weight, a warning half and an error none. How the SEO score works
