Why SSL Certificates Matter

SSL (Secure Sockets Layer) certificates encrypt the connection between your website and visitors, protecting sensitive data like passwords and credit card numbers. They're essential for:

🔒 Security
Encrypts data in transit
✓ Trust
Shows the padlock icon in browsers
📈 SEO
Google ranks HTTPS sites higher
📋 Compliance
Required for PCI DSS, HIPAA, etc.

What Happens When SSL Expires?

When your SSL certificate expires, browsers display scary warning messages to visitors. Most users will leave immediately, and search engines may penalize your rankings. For e-commerce sites, an expired certificate means lost sales and damaged reputation.

SSL Certificate Best Practices

  • Monitor expiry dates — Set up automated alerts at 30, 14, and 7 days before expiry
  • Use auto-renewal — Services like Let's Encrypt offer free auto-renewing certificates
  • Check the full chain — Ensure intermediate certificates are properly configured
  • Use strong protocols — Disable TLS 1.0/1.1, use TLS 1.2 or 1.3
