Redirect Map Checker
A redirect map checker reviews your list of old and new addresses before you put it live. Paste the pairs and this free tool finds redirects that loop, chains that pass through several steps, the same old address sent to two places, and duplicate rows. It can also rewrite every chain so it points straight to the final address.

A → B → C (Final Destination)What is a redirect map checker and when should you use it?
A redirect map is the list you prepare before a site move or a URL clean-up. Mistakes in the map become mistakes on the live site: a loop stops a page from loading, and a chain sends visitors through extra steps. Checking the map first is quicker than fixing the server later. Turn the checked list into code with the .htaccess Redirect Generator or the Nginx Redirect Generator. You can also clean messy spreadsheets with our Bulk Redirect Formatter or generate standalone page tags with our Redirect Code Generator. Auditing redirect maps before deployment prevents crawling loops, multi-hop redirect chains, and 404 crawl errors. Once your map is verified, generate server configuration rules using the .htaccess Redirect Generator for Apache or the Nginx Redirect Generator for NGINX. For large site migrations, standardize redirect syntax using the Bulk Redirect Formatter, validate legacy-to-new parity with the Old vs New URL Mapping Validator, and export plugin-ready files with the WordPress Redirection CSV Builder. Coordinate your technical transition with the SEO Migration Checklist Generator, protect on-page copy using the Content Change Comparison Tool, test pattern expressions with the Regex Tester, clean URL datasets with the CSV Deduplicator, and inspect URL paths with the URL Parser.

Result interpretation & practical applications
When evaluating the output of the redirect map checker, review the parsed metrics against your specific site architecture. Outputs are formatted for direct implementation into your HTML source, web server configuration, or Google Search Console audit files.
Always inspect generated values for contextual nuance. Automated tools highlight structural patterns, but manual verification confirms that technical directives align with your overarching SEO strategy.
Technical rules and limitations
- Permanent redirects (301 and 308) tell Google the new address should be the one shown in results; temporary ones (302, 303, 307) keep the old address.
- Each extra step in a chain is one more request for the visitor.
- The checker never visits your URLs; it only checks the list.
Google's guide to redirects and Google Search and the HTTP semantics in RFC 9110 specify standard redirect behavior.
Common mistakes and troubleshooting
- Sending page A to B and B back to A.
- Leaving old chains from earlier moves in place.
- Sending one old address to two different new ones.
- Mixing temporary and permanent codes in one chain.
No tool can promise how a search engine will crawl, index, or rank your pages. This tool generates and validates code against documented technical specifications; you determine where to deploy it, and you should always test changes on staging environments first.
