Encountering a mix of http:// and https:// in the canonical URL of your WordPress website can be puzzling. This issue can affect your site’s SEO, user experience, and overall credibility. In this article, we’ll explore the root causes of this problem, its potential impact, and the steps you can take to resolve it effectively.

What is a Canonical URL?
A canonical URL is an HTML tag used to tell search engines the preferred version of a web page. It helps avoid duplicate content issues by specifying the authoritative page when multiple versions of the same content exist. For example, if your site is accessible via both http:// and https://, the canonical URL ensures search engines index the correct one.
However, when the canonical URL includes both http:// and https://, it signals a misconfiguration in your WordPress settings or hosting environment.
Why Does This Problem Occur?
The issue usually arises due to misconfigured settings, conflicts in plugins, or improper migration practices. Here are some common causes:
- Mixed Content Configuration:
- If your site hasn’t been fully migrated to HTTPS, some resources might still load over HTTP, leading to mixed content issues.
- Improper WordPress Settings:
- Incorrect entries in the WordPress Address (URL) and Site Address (URL) fields in your WordPress settings can cause the canonical URL to include both protocols.
- Cache Plugins or CDN Conflicts:
- Misconfigured caching plugins or Content Delivery Networks (CDNs) can serve pages with inconsistent protocols.
- Hardcoded URLs in Theme or Plugins:
- Some themes or plugins may use hardcoded http:// URLs, leading to inconsistencies.
- Insecure Redirects:
- If your site’s .htaccess file or server settings have incomplete or incorrect redirect rules, they may not enforce HTTPS properly.
- SSL Certificate Issues:
- An improperly installed SSL certificate can lead to some pages being served over HTTP instead of HTTPS.
Why Does This Matter?
Having both http:// and https:// in your canonical URL can create several issues:
- SEO Problems:
- Search engines may view the http:// and https:// versions as duplicate content, splitting your ranking power.
- Reduced Credibility:
- Visitors may see security warnings when accessing http:// pages, leading to trust issues.
- Lower Page Load Speed:
- Mixed content may prevent certain resources from loading securely, impacting site performance.
- Non-compliance with Google Standards:
- Google prioritizes HTTPS sites, and inconsistencies can harm your SEO rankings.
How to Fix This Issue
Follow these steps to resolve the issue:
1. Check WordPress URL Settings
Go to Settings > General in your WordPress dashboard and ensure that:
- WordPress Address (URL) is set to https://yourdomain.com.
- Site Address (URL) is set to https://yourdomain.com.
2. Force HTTPS with .htaccess
Add the following code to your .htaccess file to redirect all traffic to HTTPS:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
</IfModule>
3. Update Hardcoded URLs
Search for hardcoded http:// URLs in your theme and plugin files. Replace them with https:// or relative URLs. You can use plugins like Better Search Replace to streamline this process.
4. Fix Mixed Content Issues
Use tools like WhyNoPadlock or Chrome DevTools to identify insecure resources and update them to HTTPS.
5. Reconfigure Cache and CDN Settings
Ensure your caching plugin (e.g., WP Rocket, W3 Total Cache) and CDN (e.g., Cloudflare) enforce HTTPS across all assets. Clear the cache after making changes.
6. Install an SSL Plugin
Install and activate a plugin like Really Simple SSL to automate the process of enforcing HTTPS.
7. Test Your Website
After making changes, test your site to confirm the issue is resolved:
- Use tools like Google Search Console to check canonical tags.
- Verify that all pages redirect to HTTPS using tools like Redirect Checker.
Final Thoughts
Fixing the issue of http:// and https:// in your WordPress canonical URL is crucial for maintaining your site’s SEO health, security, and user experience. By addressing the root causes and implementing the solutions outlined above, you can ensure that your site adheres to best practices and performs optimally.
