Free WWW vs Non-WWW Canonical Redirect Checker
Test domain canonicalization, verify 301 permanent redirects, and prevent duplicate content indexation penalties.
Quick Answer & Overview
A WWW redirect checker verifies whether the www and non-www versions of a website resolve to a single canonical URL via a permanent 301 HTTP redirect. Proper canonical redirects prevent duplicate content penalties and consolidate domain search authority.
Enter Web Domain Name
Provide your root domain address (e.g. yourwebsite.com) without specifying prefixes.
Simultaneous Dual Requests
Our scanner sends separate HTTP requests to both http://yourdomain.com and http://www.yourdomain.com.
Trace HTTP Status Redirects
Verify whether 301 Moved Permanently status codes funnel both variants into a single HTTPS canonical URL.
Consolidate Link Equity
Ensure search engines pass 100% of backlinks to one unified domain version to maximize domain authority.
Quick Answer: What is a WWW vs. Non-WWW Redirect Checker?
A WWW vs. Non-WWW Redirect Checker tests whether your domain resolves to a single unified canonical address (either https://example.com or https://www.example.com). If both versions respond without a 301 permanent redirect, search engines treat them as duplicate websites, diluting domain authority and splitting backlinks.
Domain Canonicalization Health Scenarios
| Redirect Configuration | HTTP Response Code | SEO Health Status | Action Needed |
|---|---|---|---|
| 301 Permanent Redirect | 301 Moved Permanently | Optimal (Passing 100% Equity) | None required; website is properly canonicalized. |
| 302 Temporary Redirect | 302 Found | Suboptimal (Equity not passed) | Update web server configuration to permanent 301. |
| No Redirect (Both Return 200) | 200 OK on both | Duplicate Content Hazard | Immediately set up server-side 301 redirect rule. |
Frequently Asked Questions
What is the difference between WWW and Non-WWW domains?
Technically, www is a subdomain of your root domain. While both formats serve the identical website, search engines treat https://example.com and https://www.example.com as two separate websites unless a 301 redirect is configured.
Which domain format is better for SEO: WWW or Non-WWW?
Google does not prefer one format over the other. What matters strictly for SEO is consistency: choosing one version as canonical and permanently redirecting all alternate variations to it.
What happens if a website does not redirect WWW to Non-WWW?
Without a canonical redirect, both versions can get indexed by search engines. This leads to duplicate content penalties, split backlink equity, and lower overall search ranking performance.
Which HTTP redirect status code should be used?
Always use a 301 Moved Permanently redirect. 301 redirects tell search bots that the change is permanent, transferring nearly all accumulated PageRank authority to the target canonical URL.
How do I configure a WWW redirect in Apache or Nginx?
In Apache, add RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC] and RewriteRule ^(.*)$ https://%1/$1 [R=301,L] to your .htaccess. In Nginx, declare a separate server block listening to the www host and return 301 https://$host$request_uri;.
