What is an SSL Certificate?
SSL (Secure Sockets Layer) is a digital certificate that provides a secure, encrypted connection between a website's server and a visitor's web browser. When a website has a valid SSL certificate, its URL starts with https:// instead of http://, and a padlock icon appears in the browser's address bar.
Why Do You Need an SSL Checker?
- Prevent Expiration: SSL certificates are not permanent; they usually expire after 90 days to 1 year. If your certificate expires, browsers will block users from entering your site with a massive red warning reading "Your connection is not private."
- Verify Proper Installation: Sometimes, an SSL certificate is installed, but intermediate certificates (the chain of trust) are missing. This works on some desktop browsers but fails on mobile devices.
- SEO Rankings: Google has officially confirmed that having a secure HTTPS connection is a ranking signal. Sites without SSL are penalized in search results.
