Why is SSL important?

SSL encrypts data transmitted between a user's browser and the web server, protecting sensitive information like passwords and credit card numbers from interception.

What happens if my certificate expires?

Browsers will show a severe security warning (e.g., "Your connection is not private") to visitors, which severely impacts trust and traffic.

How often should I check SSL?

It's best practice to monitor SSL expiration continuously. Certificates typically expire every 90 days (Let's Encrypt) or every 1 year.
