Bulk Redirect Mapper — 301 Rules for Site Migrations
Auto-generate 301 redirect mapping rules for site migrations. Upload old URLs and get Apache, Nginx, or CSV redirect rules instantly. Free migration tool.
What is a Bulk Redirect Mapper?
The Bulk Redirect Mapper generates the redirect configuration rules you need when migrating URLs en masse. Paste your list of old URLs and corresponding new destination URLs, and the tool outputs complete redirect rules in your choice of format — Apache .htaccess, Nginx server block, or CSV — ready to copy and deploy to your server or CDN without manual rule-writing.
When Should You Use Bulk Redirect Mapper?
Use this before any site migration: CMS replatform, URL structure change, domain consolidation, or HTTPS switchover. Redirect mapping is one of the most time-consuming parts of any migration, and getting it wrong means permanent loss of rankings for affected URLs as their link equity fails to transfer. This tool converts a migration spreadsheet into deployable rules in minutes rather than hours of manual configuration.
How to Read Bulk Redirect Mapper Results
Review the output carefully before deploying — check that no old URL patterns are accidentally too broad. A pattern matching /products will also match /products-old and any other URL beginning with that string unless anchored precisely. After deploying, test a representative sample of the generated rules using the Bulk Redirect Checker or Redirect Chain Checker to confirm they fire correctly and each old URL reaches the intended new destination in a single hop.
What Should You Know Before Using Bulk Redirect Mapper?
Build your redirect map in a spreadsheet with one column for old URLs and one for new destinations before using this tool, sorted by page importance (organic traffic, backlinks) so you can prioritise fixing errors in your most valuable redirects first. After deploying, monitor Google Search Console's Coverage report for a spike in 404 errors in the week following launch — any new 404s indicate missing redirect rules that need to be added before rankings for those URLs are permanently lost.
Frequently Asked Questions
What is a redirect map and why do I need one for a migration?
A redirect map is a spreadsheet of old URLs paired with their new destination URLs, used to configure 301 redirects during a site migration. Without a redirect map, traffic and PageRank accumulated by old URLs is lost when those URLs return 404 after the migration. The Bulk Redirect Mapper converts your spreadsheet into deployable server configuration rules.
How do I create redirect rules in Apache .htaccess?
The Bulk Redirect Mapper generates Apache .htaccess redirect rules in the correct Redirect or RewriteRule syntax. Paste your old and new URL pairs and select Apache as the output format. The tool handles path-only redirects, full-URL redirects, and domain changes. Copy the generated rules into your .htaccess file and test with the Bulk Redirect Checker after deployment.
How do I create redirect rules for Nginx?
Select Nginx as the output format in the Bulk Redirect Mapper. The tool generates rewrite directives in correct Nginx syntax for your server block configuration. Place the generated rules in the appropriate server block and reload Nginx. Test each rule with the Bulk Redirect Checker after deployment to confirm the redirects are firing correctly.
What should I do if a redirect is missing after a migration?
Monitor Google Search Console's Coverage report and your site's 404 error rate in the week after migration. Any new 404s appearing after launch indicate missing redirect rules. Use the Bulk Status Checker to identify which old URLs are returning 404, add them to your redirect map, and deploy the missing rules immediately to prevent ranking loss.
How far in advance should I prepare my redirect map?
Prepare your redirect map before the migration goes live — ideally two to four weeks in advance. Map every URL that has organic traffic, backlinks, or internal links pointing to it. Sort by importance (organic traffic, referring domains) so you can prioritise fixing errors in the most valuable redirects. Test the complete map in a staging environment before the live cutover.
