Review the certificate details, including the expiration date, common name, issuer, and any intermediate certificates.

Ensure that the website's HTTPS connection is secure and does not trigger any browser warnings indicating potential security risks.
By following these steps, you can effectively verify the validity of an SSL certificate and ensure that the website you are visiting utilizes a secure and trusted SSL configuration.
