Why Redirect Mapping Is Critical for Migrations
Protect Rankings During URL Changes
During replatforms and URL structure updates, unmapped legacy URLs are one of the biggest SEO risk factors. A clean 301 map protects link equity, preserves indexed URLs, and reduces crawl waste. This tool accelerates mapping by suggesting likely targets while still giving you full manual control over final destinations.
Confidence-Based Workflow
Exact and unique slug matches are marked high confidence, while token similarity matches are marked medium or low for manual review. This helps teams prioritize QA effort where it matters most.
How to Use This Tool
Input Old and New URL Sets
Paste URL lists directly or upload `.xml`, `.txt`, or `.csv` files for both the old site and the new site.
Generate the Mapping
Run automatic matching to produce a redirect table with confidence scores and matching methods.
Review Low-Confidence Rows
Filter by confidence and update destination URLs in-line to finalize any uncertain mappings.
Export Implementation Files
Download CSV for documentation or export direct redirect rules for Next.js, Apache `.htaccess`, or Nginx.
