What is domain canonicalization & how it works
Every site is reachable as up to four variants — http/https × www/non-www. Search engines treat each as a separate URL, so unless they all funnel to one canonical address you can split ranking signals, duplicate content, and confuse analytics.
The fix is a consistent chain of 301 redirects from every variant to a single preferred host, ideally over HTTPS. This test requests all four variants, follows each redirect chain, detects loops, and reports whether they converge on one canonical host.
Canonical host
The single preferred version (e.g. https://example.com) all variants point to.
301 redirect
A permanent redirect that passes ranking signals to the target URL.
Redirect loop
A misconfiguration where variants redirect to each other endlessly.
How to use this tool
1
Enter a domain
Type a domain, e.g.
example.com — no scheme needed, all four variants are tested.2
Run the test
Click Test Redirection to request http/https and www/non-www and follow every redirect chain.
3
Review the chains
See each variant’s redirect path, the canonical host, and any loops or failures.
4
Fix the gaps
Add 301 redirects from every variant to your one canonical HTTPS host, then re-test.

Frequently asked questions
5 Q&A
Search engines treat www, non-www, http and https as separate URLs. If they resolve independently, ranking signals and crawl budget get split across duplicates. Redirecting all variants to one canonical URL consolidates that value.
Use a 301 (Moved Permanently) redirect. It tells search engines the move is permanent and passes ranking signals to the target, unlike a 302 (temporary) redirect which does not.
A redirect loop happens when variants redirect to each other endlessly (e.g. www → non-www → www), so browsers and crawlers never reach a final page. This test flags any variant that loops.
Yes. Redirect every http:// variant to its https:// equivalent as part of the same canonical chain, and pair it with HSTS so browsers upgrade automatically on future visits.
