How to use the Redirect Mapping Tool
- Paste the old and new URLs, choose sitemaps or CSV files, or try the example.
- Select Suggest redirects and review each match, starting with medium and low confidence.
- Download the map as a CSV, or copy the pairs into the Redirect Rules Generator.
Supported files and limits
- Matches by the same address with a different ending (.html, trailing slash), then the same page name, then the words the addresses share, such as /products/oregano-dried.html and /shop/dried-oregano/.
- Old pages without a match can fall back to the closest section that still exists. Pages that are gone are listed, not sent to the home page.
- Only the addresses are compared; no pages are fetched. Domains are ignored, so old and new sites can have different domains.
- Up to 10,000 old and 10,000 new URLs. Sitemap index files are not followed: use their child sitemaps.
Common questions
What is a redirect map?
A list of every old URL of a website next to the new URL it should redirect to. It is the plan for a migration: the 301 redirects are written from it, so visitors and search engines land on the right page.
How accurate are the suggestions?
High confidence matches share the page name or nearly all words. Medium and low ones are a starting point: two addresses can share words without the pages being about the same thing, so check them before you use the map.
Should old pages without a match redirect to the home page?
No. Google treats a redirect to an unrelated page, like the home page, as a missing page. Redirect to a close equivalent or the section it belonged to, or let it return 404 or 410.
Are my URL lists sent anywhere?
No. The lists are compared in your browser and nothing is sent to our server or anyone else.
