In today’s digital age, securing your WordPress website isn’t optional; it’s essential. If you’ve ever wondered how to use an SSL certificate in WordPress, you’re in the right place. At WPDesigns, we help UK businesses create stunning, secure, and high-performing WordPress websites. One of the most vital steps in building user trust and improving SEO performance is installing and activating an SSL certificate.
This comprehensive guide explains how to install, enable, and set up an SSL certificate on WordPress, why it matters, and how it keeps your website safe from online threats.
Why an SSL Certificate Matters for WordPress Security
Before you set up SSL for WordPress, it’s important to understand what it does. SSL (Secure Sockets Layer) is a technology that encrypts the connection between your website and its visitors. This ensures that sensitive data such as login credentials, payment information, and contact forms remain private and protected.
When SSL is active, your website URL starts with https:// instead of http://. The “S” stands for “secure,” and browsers display a padlock symbol beside your website address.
Without SSL, users may see “Not Secure” warnings when they visit your website, which can hurt credibility and SEO rankings. In contrast, a site secured with SSL not only builds trust but also improves your chances of ranking higher on Google, as HTTPS is now a ranking factor.
Step-by-Step Guide: How to Use an SSL Certificate in WordPress
Here’s a simple, practical approach to installing and activating SSL for your WordPress website.
1. Obtain an SSL Certificate
The first step is acquiring an SSL certificate. Many web hosting providers, such as SiteGround, Bluehost, and WP Engine, offer free SSL certificates through Let’s Encrypt. This is the easiest and most reliable way to secure your website at no extra cost. Alternatively, if you require higher-level validation or warranties, you can purchase a premium SSL certificate from providers like Comodo, DigiCert, or Sectigo.
At WPDesigns, we recommend Let’s Encrypt for most small and medium WordPress sites as it provides robust encryption with minimal setup.
2. Activate and Install SSL on Your Hosting Account
Once you’ve obtained your SSL certificate, the next step is activation. Most hosting dashboards include an SSL or Security section where you can easily turn on HTTPS. In many modern hosting environments, SSL installation is fully automated; simply click ‘Enable SSL’ or ‘Activate HTTPS’ and your certificate will be installed.
If your web host doesn’t offer automated activation, you can contact their support team to guide you through the setup process.
3. Enable HTTPS on Your WordPress Site
After installing the SSL certificate, you’ll need to update your website’s settings so WordPress uses HTTPS.
Go to your WordPress Dashboard → Settings → General, and change both the WordPress Address (URL) and Site Address (URL) to start with https://.
This ensures all new traffic and links use the secure version of your site.
4. Update Internal Links and Media URLs
Even after switching to HTTPS, some old images, links, or scripts may still load over HTTP, causing mixed content errors in WordPress. These errors prevent your site from showing the padlock icon.
You can fix this by updating your internal links and media URLs. Tools like “Better Search Replace” or built-in hosting features can scan and correct outdated URLs automatically.
Quick Tip: Keeping all your website content secure ensures users never face browser warnings or insecure resource issues.
5. Use a Plugin to Simplify SSL Management
If you prefer a hands-off approach, installing a plugin such as Really Simple SSL can make the process effortless. Once activated, it automatically detects your SSL certificate, updates your URLs, and redirects visitors from HTTP to HTTPS.
This is particularly useful for beginners who want to enable HTTPS on WordPress without manually editing settings or configurations.
6. Redirect All Visitors from HTTP to HTTPS
To ensure everyone visits the secure version of your site, you must redirect HTTP traffic to HTTPS. This guarantees your website always loads safely and consistently.
If your hosting provider supports automatic redirects, enable them in your dashboard. Alternatively, security or SEO plugins often provide built-in redirection tools that make the process seamless.
7. Verify and Test Your SSL Setup
Once everything is configured, it’s time to check your SSL installation. Visit your website and confirm that the padlock symbol appears in the browser’s address bar.
You can also use SSL Labs’ SSL Test tool to verify that your certificate is correctly installed and rated as secure. This final step confirms that your site is fully protected and ready for visitors.
Extra Benefits of Using SSL in WordPress
Beyond data protection, SSL offers multiple advantages:
- Improved SEO: Google rewards HTTPS-enabled sites with better visibility.
- Higher Trust: Visitors are more likely to engage when they see the padlock icon.
- Enhanced Compliance: Many regulations require encrypted data transfer.
- Better Conversions: Secure websites encourage form submissions and sales.
Using SSL also helps differentiate your brand as professional, safe, and trustworthy, qualities that visitors and search engines value highly.
Common Issues: Fixing Mixed Content and Redirect Errors
Sometimes, after activating SSL, you may notice that your website still shows insecure warnings. This often happens due to mixed content errors, when some resources (like images or stylesheets) still load using HTTP.
To resolve this:
- Update all links to HTTPS.
- Clear your caching plugin or CDN cache.
- Ensure your theme and plugins are updated.
If the issue persists, contact your hosting support or a WordPress developer. At WPDesigns, we handle this for clients as part of our maintenance service.
