The problem
Why manual URL mapping breaks at scale
Building a redirect map by hand takes days and is highly error-prone.
Missed redirects cause 404s, lost rankings and broken user journeys.
Spreadsheets cannot explain why two URLs match - making redirect QA painful.
URL mapping explained
What is URL mapping in SEO?
URL mapping in SEO is the process of connecting every important old URL to the best matching new destination before a migration goes live. The result is a reviewed URL map that keeps legacy entry points connected to relevant pages.
A URL mapping tool or URL mapping generator speeds up that work by comparing old and new crawl exports, suggesting matches and showing why each URL pair was selected.
URL matching is the comparison step, URL mapping is the reviewed old-to-new dataset, and redirect mapping turns that dataset into the 301 rules used during a website migration.
This is not a URL shortener or a basic redirect checker. It is a purpose-built URL mapper and URL redirect mapper for planning, reviewing and exporting redirects before a migration goes live.
02
URL mapping
The approved old-to-new pairs form a complete URL map, including confidence scores, review states and migration QA notes.
03
Redirect mapping
The accepted redirect map can be exported as CSV or JSON, or sent to Google Drive with its match details.
How it works
How the URL mapping generator builds your redirect map
01
Add both URL sets
Upload CSV, TSV, Excel or JSON, crawl the sites, or reuse a project.
02
Run the pipeline
Fixed matching stages process only the URLs that earlier stages leave open.
03
Review and approve
Filter by type, score, status and guard flags, then use row or bulk actions.
04
Export accepted matches
Download CSV or JSON, or send the reviewed result to Google Drive.

Safety guards

Use cases
URL redirect mapping for every migration type
01
Replatforming
Move from one CMS to another while keeping old paths and their proposed new destinations in a reviewable file.
Product, category and content URLs often follow different rules. Match them in one workspace without treating every page type as interchangeable.
Magento → Shopify - category & product flows
WordPress → Headless - slug normalization
Custom CMS migrations - any source format
Review states - accepted, review or blocked
02
Domain consolidation
Merging multiple domains or subdomains into one canonical structure with safe locale-aware redirects.
Multi-brand mergers and international consolidations need locale guards - match nl/de/en separately, not as one pile.
Multi-brand merge - preserve link equity
Subdomain to folder - blog., shop. → /
International consolidation - per-locale matching
Locale guard - no cross-language mixups
03
Site restructure
Reorganize URL hierarchy, rename categories or normalize slugs while keeping the old-to-new decisions visible.
Even small slug changes accumulate fast. Pattern recognition picks up entire family rewrites in one pass.
Category renames - family-level mapping
Depth changes - /a/b/c → /a/c flattening
Slug normalization - casing, dashes, accents
Pattern detection - auto-learn rewrites
