Why You Need an SSL Certificate
SSL (Secure Sockets Layer) encryption secures data exchanged between servers and users. By encrypting sensitive details, like personal data and payment information, an SSL certificate keeps it safe from third parties.
Additionally, sites with SSL tend to rank higher on search engines, and browsers label sites without SSL as “Not Secure.” With our SSL Certificate Checker, website owners can easily ensure their SSL setup is working as intended.

Common SSL Certificate Errors
SSL certificate issues can prevent your website from being fully trusted by web browsers, causing warnings or blocking users from accessing your site. Below are some common SSL errors and solutions:
- Expired SSL Certificate: An expired SSL certificate disrupts the secure connection. Renew your certificate promptly to keep your HTTPS status intact and maintain user trust.
- Certificate Chain Issues: If the chain of trust to a recognized root certificate authority (CA) is broken, browsers may show warnings. Installing the intermediate certificates correctly will resolve this.
- Mismatched Domain Name: If the domain on the certificate doesn’t match the URL domain, browsers may display security alerts. Double-check that the certificate is issued to the correct domain name to avoid disruptions.
- Self-Signed Certificate: Self-signed certificates aren’t recognized by most browsers. To establish trust, use an SSL certificate from a reliable certificate authority.
- Untrusted Certificate Authority: If the certificate is issued by an unknown CA, it may be flagged as insecure. Always use trusted SSL providers for a seamless experience.

Types of SSL Certificates
SSL certificates come in several types, each suited for different levels of security and trust:
- Domain Validation (DV): Verifies ownership of the domain, providing basic encryption. Ideal for smaller websites and blogs.
- Organization Validation (OV): Confirms both domain ownership and organization identity, adding a layer of trust for users.
- Extended Validation (EV): Provides the highest level of validation by thoroughly verifying the organization. EV certificates show a green address bar or padlock, enhancing credibility.
- Wildcard SSL: Covers a primary domain and all its subdomains, making it cost-effective for sites with multiple subdomains.
- Multi-Domain SSL (SAN): Secures multiple domains and subdomains with a single certificate, ideal for businesses managing several sites.
Each type varies in validation level, coverage, and cost, allowing website owners to choose based on their security needs.
Tips for SSL Installation
When installing SSL, follow these best practices:
- Use a Trusted Certificate Authority (CA): Choose a CA that’s widely trusted to establish credibility.
- Follow the Correct Installation Steps: Each server (e.g., Apache or NGINX) has specific steps for SSL installation. Incorrect steps can lead to issues, so follow instructions carefully.
- Test Regularly with the SSL Checker: Even after installation, use the tool periodically to confirm SSL validity.
- Monitor Expiration Dates: SSL certificates need regular renewal, and our tool highlights expiration dates so you can plan accordingly.
