Verify that all URL variants resolve to a single canonical. Our Canonical Checker tests http/https and www/non-www combinations, follows redirect chains, reports status codes, and supports bulk URL checking with 20+ user agents — helping you prevent duplicate content and consolidate ranking signals.
Duplicate content is one of the most common (and most overlooked) SEO problems. If the same page is accessible at multiple URLs without a canonical tag pointing to the preferred version, search engines have to guess which one to rank — and they often guess wrong. This tool checks any URL's canonical setup so you can catch issues before they silently erode your rankings.
Why Check Canonical URLs?
Redirect Chain Analysis
See the complete redirect chain for each URL variant. Identify unnecessary redirect hops that slow down crawling and waste link equity. Know exactly where http, https, www, and non-www requests end up.
Duplicate Content Prevention
When multiple URL variants serve the same content without proper redirects, search engines may index duplicates, splitting ranking signals. This tool verifies all variants converge to a single canonical URL.
Multi-Agent Testing
Test how your redirects behave for different user agents — Googlebot, Bingbot, Chrome, Safari, Facebook crawler, and more. Some servers redirect differently based on the requesting agent.
Bulk URL Checking
Switch to list mode to check up to 50 URLs at once. Get HTTP status codes, redirect counts, and final URLs for every entry. Export results as CSV for reporting.
