Enter a URL
To human visitors, entering [www.example.com](https://www.example.com) or simply example.com might feel identical, but search engine crawlers interpret them as two entirely independent websites hosted on different hostnames. If both versions are active and one does not permanently redirect to the other, search bots will index both domains simultaneously. This creates massive duplicate content issues, dilutes page authority, and confuses search algorithms. The A2ZRank WWW Redirect Checker is an instant, browser-based diagnostic utility designed to verify whether your domain correctly routes traffic to a single preferred canonical version using clean HTTP 301 redirects.
If you find that your domain is not redirecting properly, generate the necessary server configuration directives using our URL Rewriting Tool. Furthermore, to audit whether internal pages are pointing to mixed hostnames, crawl your site architecture with our Link Analyzer.
Configuring a single primary domain version is one of the most critical foundational technical SEO requirements. A proper 301 permanent redirect provides key structural benefits:
Consolidates Link Equity (PageRank): When third-party websites link to you, some link to the www version while others link to the non-www version. A permanent redirect consolidates all backlink equity into one unified domain authority score.
Prevents Duplicate Content Penalties: Search engines penalize sites displaying identical text across multiple URLs. Proper canonicalization ensures only one version appears on search engine results pages (SERPs).
Guarantees Seamless SSL & Security: Mixed setups frequently lead to SSL certificate mismatches and browser security warnings (e.g., "Your connection is not private") if the security certificate does not cover both wildcard subdomains.
Improves Web Analytics Accuracy: Running two versions splits traffic metrics in Google Analytics and Google Search Console, complicating accurate traffic and conversion reporting.
Enhances User Experience: Users expect your website to load effortlessly, regardless of how they type the address into their mobile or desktop address bars.
Instant Dual-Version Inspection: Tests both http://, https://, www, and non-www variations simultaneously to identify redirect loops or broken paths.
HTTP Status Code Verification: Reports exact server response headers, highlighting whether redirects use permanent 301 Moved Permanently, temporary 302 Found, or return direct 200 OK errors on both variants.
Canonical Consistency Report: Confirms whether the destination URL matches standard canonical tag declarations across your website.
Fast and Lightweight: Runs directly in your browser without requiring server installations, plugins, or third-party access tokens.
100% Free & Unlimited: Perform health checks across multiple personal, client, or competitor domains with zero usage restrictions.
Auditing your website’s redirect configuration takes four simple steps:
Enter Your Domain Name: Type or paste your root domain (e.g., example.com) into the input field.
Click "Check Redirect": The tool sends automated HTTP requests to both www and non-www protocols.
Inspect the Redirect Chain: Review the HTTP response headers to see if one version cleanly forwards to the primary version via an HTTP 301 status code.
Take Remedial Action: If both versions return a 200 OK status without redirecting, implement a 301 rule in your .htaccess, Nginx server block, or Cloudflare DNS dashboard.
No. Search engines have no algorithmic preference between [www.example.com](https://www.example.com) and example.com. What matters is choosing one preferred standard and consistently redirecting the other version to it.
Always use a 301 Moved Permanently redirect. A 301 redirect informs search engine crawlers that the move is permanent, ensuring 100% of accumulated link equity transfers to the canonical version.
Yes. If both versions are active without redirection, Google Search Console will flag pages with "Duplicate without user-selected canonical" or split your performance impressions across two separate domain properties.
