HTTPS has become a standard requirement for modern websites. Installing an SSL certificate on a WordPress website helps protect visitor data, improve trust and create a secure connection between browsers and servers.
Although many hosting providers now offer free SSL certificates, WordPress website owners still need to configure HTTPS correctly to avoid security warnings and mixed content issues.
This guide explains how to install SSL certificate on WordPress website, configure HTTPS settings and ensure your website works correctly after migration from HTTP to HTTPS.
Why Install SSL Certificate on WordPress?
An SSL certificate encrypts communication between visitors and your website server.
Installing SSL provides several benefits:
- Protects user information
- Enables HTTPS connection
- Improves visitor trust
- Supports website security
- Creates a better technical SEO foundation

The general installation process includes:
- Open your hosting control panel.
- Find SSL or Security settings.
- Select your domain name.
- Install or activate the SSL certificate.
- Wait for certificate verification.
Step 3: Change WordPress Website URL to HTTPS
After installing SSL, WordPress needs to use HTTPS instead of HTTP.
Go to:
WordPress Dashboard → Settings → General
Change:
http://example.com
to:
https://example.com
Update both:
- WordPress Address (URL)
- Site Address (URL)
Step 4: Force HTTP Redirect to HTTPS
After enabling SSL, all visitors should automatically access the secure HTTPS version.
HTTP to HTTPS redirect prevents:
- Duplicate URLs
- Security warnings

- Incorrect indexing
Many hosting providers offer automatic HTTPS redirect options.
Step 5: Fix WordPress Mixed Content Issues
Mixed content happens when an HTTPS website still loads some resources through HTTP.
Common causes include:
- Old image URLs
- HTTP scripts
- Theme resources
- Plugin files
Solutions include:
- Update HTTP links to HTTPS
- Replace old media URLs
- Check theme settings
- Review plugin resources
Step 6: Update WordPress Database URLs
Some old HTTP URLs may remain inside the WordPress database.
Database updates may be required for:
- Posts
- Images
- Internal links
- Plugin settings
Step 7: Update Google Search Console
After switching WordPress to HTTPS, website owners should update search engine tools.
Recommended actions:
- Add HTTPS property
- Submit updated sitemap
- Monitor indexing status
- Check security issues
Step 8: Update Internal Links
Internal links should use HTTPS URLs after SSL installation.

- Navigation menus
- Blog articles
- Footer links
- Images
Step 9: Verify SSL Installation
After completing setup, confirm that SSL works correctly.
请检查：
- Browser lock icon
- HTTPS URL
- No security warnings
