SSL Certificate Checker

Why Use an SSL Certificate Checker?

Our free SSL Certificate Checker allows you to instantly check the status of your website’s SSL certificate. With just a domain name, you can find out if your SSL is active, valid, and trusted, along with details such as the issuer, issue date, and expiry date. This tool is designed for website owners, developers, IT professionals, and SEO experts who want to ensure their websites remain safe, compliant, and secure.

Expired or misconfigured SSL certificates can cause browsers to display “Not Secure” warnings, scaring away visitors and damaging your SEO rankings. Our checker helps you proactively monitor SSL health and avoid unexpected downtime or security issues.

What Is an SSL Certificate?

An SSL Certificate (Secure Sockets Layer) is a digital certificate that encrypts the communication between a user’s web browser and the website server. By using HTTPS instead of HTTP, SSL ensures that all sensitive information — such as login credentials, banking details, and personal data — is transmitted securely. SSL certificates are issued by trusted Certificate Authorities (CAs) such as Let’s Encrypt, DigiCert, GoDaddy, GlobalSign, and Sectigo.

Today, SSL is not just about security. It has also become a mandatory SEO ranking factor. Google and other search engines favor HTTPS-enabled websites, meaning SSL can directly impact your website’s visibility and organic traffic.

When Should You Check SSL Certificates?

Regularly monitoring your SSL certificates is crucial for security, SEO, and user experience. Here are some cases when you should run an SSL check:

• ✔️ Before your SSL certificate expires (avoid downtime)
• ✔️ After migrating your website to a new hosting provider
• ✔️ To verify correct installation of SSL on your domain
• ✔️ To troubleshoot SSL-related errors and mixed content warnings
• ✔️ During audits for compliance, SEO, or performance

Frequently Asked Questions (FAQs)

1. What happens if my SSL certificate expires?

Once an SSL certificate expires, browsers will show a “Not Secure” warning. Users may refuse to enter personal details or make purchases, which can significantly reduce trust, conversions, and SEO rankings.

2. How often should I check SSL certificates?

You should check SSL certificates at least once a month, especially if your provider issues short-term certificates (e.g., Let’s Encrypt, which is valid for only 90 days).

3. Can this tool check SSL for any domain?

Yes, our SSL checker works for any domain with HTTPS enabled. Simply enter the domain name (with or without “https://”), and our tool will fetch its SSL details.

4. How do I renew an expired SSL certificate?

To renew your SSL certificate, contact your hosting provider or Certificate Authority. Many hosts also offer free SSL renewal through Let’s Encrypt, while premium providers like DigiCert and GlobalSign provide extended validity and warranty options.

5. Does SSL affect Google rankings?

Absolutely. Since 2014, Google has considered HTTPS a ranking factor. Websites without SSL may lose visibility in search results and experience higher bounce rates due to browser warnings.
