WWW/Non-WWW Redirect Analysis

Our checker evaluates how your website handles the www and non-www versions of your domain to prevent duplicate content issues.

  • Redirect configuration: We verify that one version properly redirects to the other using permanent redirects.
  • Consistency check: We ensure both versions don't serve different content simultaneously.
  • Canonical domain: We identify your preferred domain version (www or non-www).

Based on these findings, you can implement proper redirects to consolidate your domain authority and avoid SEO penalties from duplicate content.

WWW/Non-WWW Redirect Best Practices​

❌ Bad Practice​

# Both versions accessible with no redirection
http://example.com/ - Status 200
http://www.example.com/ - Status 200
(Search engines see these as separate sites with duplicate content)

# Using temporary redirects instead of permanent
http://example.com/ → http://www.example.com/ - Status 302
(Doesn't properly consolidate link equity)

# Redirect chains
http://example.com/ → http://www.example.com/ → https://www.example.com/
(Creates unnecessary additional requests and latency)

# Inconsistent redirects across the site
http://example.com/page1 → http://www.example.com/page1
http://example.com/page2 → http://example.com/page2
(Inconsistent preferred domain signals)

# Different content on www vs. non-www versions
http://example.com/ - Shows homepage content
http://www.example.com/ - Shows different homepage content

✅ Good Practice​

# Consistent permanent redirect from non-www to www
http://example.com/ → http://www.example.com/ - Status 301
http://example.com/about → http://www.example.com/about - Status 301

# OR consistent permanent redirect from www to non-www
http://www.example.com/ → http://example.com/ - Status 301
http://www.example.com/contact → http://example.com/contact - Status 301

# Combined with HTTPS for optimal configuration
http://example.com/ → https://www.example.com/ - Status 301
http://www.example.com/ → https://www.example.com/ - Status 301

# Consistency across all pages and subdomains
All URLs follow the same redirection pattern

# Canonical tags matching redirect pattern
<link rel="canonical" href="https://www.example.com/page" />
