How to Verify Your SSL Certificate is Working Properly

In today’s digital landscape, securing your website with an SSL (Secure Sockets Layer) certificate is no longer optional—it’s essential. An SSL certificate not only encrypts sensitive data but also boosts your website’s credibility and search engine rankings. However, simply installing an SSL certificate isn’t enough. You need to ensure it’s working properly to avoid potential security risks, browser warnings, or a poor user experience.

In this guide, we’ll walk you through the steps to verify that your SSL certificate is functioning as it should. Whether you’re a website owner, developer, or digital marketer, these tips will help you maintain a secure and trustworthy online presence.

Why Verifying Your SSL Certificate Matters

Before diving into the steps, let’s quickly cover why verifying your SSL certificate is so important:

1. Data Security: A properly functioning SSL certificate ensures that data transmitted between your website and its users is encrypted and secure.
2. SEO Benefits: Google prioritizes HTTPS websites in search rankings, so a valid SSL certificate can improve your SEO performance.
3. User Trust: Visitors are more likely to trust and engage with your website if they see the padlock icon in their browser’s address bar.
4. Avoid Browser Warnings: If your SSL certificate is misconfigured or expired, users may encounter warnings like “Your connection is not private,” which can drive them away.

Now that you understand the importance, let’s explore how to check if your SSL certificate is working properly.

Step 1: Check for the Padlock Icon in the Browser

The easiest way to verify your SSL certificate is by visiting your website and looking for the padlock icon in the browser’s address bar. Here’s what to do:

1. Open your website in a browser (e.g., Chrome, Firefox, or Safari).
2. Look for a padlock icon to the left of the URL.
3. Click on the padlock to view details about the SSL certificate, such as its validity and issuing authority.

If the padlock is missing or there’s a warning, it’s a sign that your SSL certificate may not be configured correctly.

Step 2: Use an Online SSL Checker Tool

Online SSL checker tools are a quick and reliable way to test your SSL certificate. These tools analyze your certificate and provide detailed reports on its status. Popular options include:

• SSL Labs’ SSL Test: This free tool provides an in-depth analysis of your SSL certificate, including its expiration date, supported protocols, and overall grade.
• Why No Padlock?: This tool identifies mixed content issues, which occur when your website loads both secure (HTTPS) and insecure (HTTP) elements.
• SSL Checker by DigiCert: A simple tool to verify if your SSL certificate is installed correctly and valid.

To use these tools, simply enter your website’s URL, and the tool will generate a report highlighting any issues.

Step 3: Verify HTTPS Redirection

Even with a valid SSL certificate, your website may still load over HTTP if redirection isn’t set up properly. To ensure all traffic is redirected to HTTPS:

1. Type your website’s URL with “http://” in the browser.
2. Check if it automatically redirects to “https://”.
3. If it doesn’t, you’ll need to configure a 301 redirect in your server settings or .htaccess file.

Proper HTTPS redirection ensures that all users access your site securely, regardless of how they type the URL.

Step 4: Check for Mixed Content Issues

Mixed content occurs when your website loads both secure (HTTPS) and insecure (HTTP) resources, such as images, scripts, or stylesheets. This can compromise your site’s security and trigger browser warnings. To identify and fix mixed content:

1. Use browser developer tools (press F12 or right-click > Inspect) to check for mixed content warnings in the console.
2. Use online tools like “Why No Padlock?” to scan your site for insecure elements.
3. Update all resource URLs to use HTTPS instead of HTTP.

Step 5: Confirm SSL Certificate Validity and Expiration

SSL certificates have an expiration date, and failing to renew them on time can lead to browser warnings and security vulnerabilities. To check your certificate’s validity:

1. Click on the padlock icon in your browser’s address bar.
2. View the certificate details, including the expiration date.
3. Set up reminders to renew your SSL certificate before it expires.

Alternatively, SSL checker tools can also provide expiration details.

Step 6: Test Your SSL Configuration for Vulnerabilities

A properly functioning SSL certificate should be free of vulnerabilities. Use tools like SSL Labs’ SSL Test to check for:

• Weak encryption algorithms
• Outdated SSL/TLS protocols
• Vulnerabilities like Heartbleed or POODLE

Addressing these issues ensures your SSL certificate provides maximum security.

Step 7: Monitor Your SSL Certificate Regularly

SSL verification isn’t a one-time task. Regular monitoring helps you stay ahead of potential issues. Consider using automated SSL monitoring tools like:

• UptimeRobot: Monitors your SSL certificate and alerts you if it’s about to expire.
• Certbot: Automates SSL certificate renewal for websites using Let’s Encrypt.
