WordPress WWW & Non-WWW Duplicate Content Fix
What You Are Experiencing
Do any of these sound familiar?
When your WordPress site is accessible via multiple URLs—such as both www.yourdomain.com and yourdomain.com, or http:// and https://, or with and without a trailing slash—search engines see these as distinct pages. This creates wordpress www and non www duplicate content, diluting your site's authority and harming its search rankings. It's a common, critical SEO problem that needs a precise fix.
If any of these match, you are in the right place. For more general canonical issues, see our WordPress Canonical URL Wrong or Pointing to Homepage — General Fix page.
Root Cause
Why this happens
The core reason for wordpress www and non www duplicate content, HTTP/HTTPS, or trailing slash issues is often a combination of misconfigured server settings, incorrect WordPress URL settings, and sometimes conflicting plugins. When a server allows a page to load under multiple variations (e.g., http://example.com, https://example.com, https://www.example.com/, https://www.example.com), search engines treat each as a separate entity.
WordPress itself needs explicit direction. If the 'WordPress Address (URL)' and 'Site Address (URL)' in General Settings are not precisely aligned with your desired canonical, it can lead to internal links and canonical tags referencing the wrong version. Furthermore, an improperly configured SSL certificate or a lack of server-level redirects (often in .htaccess for Apache or Nginx configuration) means the server isn't forcing the correct, single URL.
This ambiguity dilutes your site's SEO authority, as link equity and ranking signals are split across multiple URLs instead of consolidating to one. It's a fundamental problem that requires a systematic approach to ensure every page has one definitive, canonical URL. For broader issues, understanding why a WordPress canonical URL might be wrong is key.
Try This First
Steps you can take right now
Work through these in order. Each step is safe unless noted otherwise.
Check WordPress General Settings
Navigate to your WordPress dashboard, then go to Settings > General. Ensure that both the 'WordPress Address (URL)' and 'Site Address (URL)' fields precisely match your desired canonical URL, including WWW or non-WWW, and HTTPS. If you want https://www.example.com, both fields should reflect this exactly. Inconsistencies here are a primary cause of wordpress www and non www duplicate content.
Verify HTTPS Configuration
If your site should be using HTTPS, ensure your SSL certificate is correctly installed and active. Many hosts provide one-click SSL installation. If your site still loads on HTTP, even after setting HTTPS in General Settings, you likely have a server-level misconfiguration or mixed content issues. This is crucial for resolving wordpress http and https duplicate content.
Implement .htaccess Redirects
Access your site's root directory via FTP or your hosting file manager and locate the .htaccess file. Before making any changes, download a backup of this file. Incorrect edits can break your site. Add rules to force WWW or non-WWW, and HTTPS. For example, to force non-WWW and HTTPS, you might add specific rewrite rules. This is a common method to consolidate URLs and prevent wordpress trailing slash duplicate content by enforcing a consistent URL structure.
RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^ https://yourdomain.com%{REQUEST_URI} [L,R=301,NE]Review Canonical Tags
Inspect the source code of your pages to see the <link rel="canonical" href="..."> tag. Ensure it points to the single, preferred version of each page. If you're using an SEO plugin like Yoast SEO or Rank Math, verify its settings for canonical URLs. Sometimes, plugins can override WordPress settings or introduce their own canonical issues. Incorrect canonicals are a direct cause of wordpress www and non www duplicate content.
If none of these steps resolved it, this is where professional help saves time.
If you've tried the above steps and your site still suffers from duplicate content issues, the problem is likely more complex, involving server configuration, database inconsistencies, or plugin conflicts. At this point, attempting further DIY fixes can risk data loss or site downtime. Our experts can quickly diagnose and resolve these intricate problems without risk.
