SEO Migration Redirect Validator
Paste old URL,new URL pairs and verify permanent redirects, final targets, chain length, and query preservation.
Free SEO Migration Redirect Validator
URL migrations fail when old URLs redirect to the wrong target, use temporary status codes, drop parameters, or create long chains. This validator checks old-to-new pairs so you can confirm that important pages preserve SEO signals after a migration.
What a healthy migration redirect looks like
A healthy migration redirect uses a permanent status such as 301 or 308, reaches the expected new URL, keeps the chain short, and preserves query parameters when those parameters matter.
Use analytics to choose the URL list
Validate the URLs that actually receive visits, links, revenue, or search clicks first. Analytics and Search Console exports make that priority list much more useful than a raw crawl alone.
Frequently Asked Questions
Should SEO migrations use 301 redirects?
Permanent migrations usually use 301 or 308 redirects. Temporary redirects can be valid for short-term tests, but they are not the usual choice for permanent URL moves.
How long is too long for a redirect chain?
Aim for one hop from old URL to new URL. More than two or three hops should usually be cleaned up.
Should query parameters be preserved?
Often yes, especially for campaign tracking and filtered landing pages. Some migrations intentionally drop parameters, but that should be explicit.
What format should I paste?
Paste one pair per line as old URL,new URL. A header row such as old,new is allowed.
