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 protects rankings, backlinks and user journeys.
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 final redirect map becomes deployable 301 rules for CSV, JSON, Apache, Nginx or a CMS import workflow.

Generate URL matches
Exact, canonical, pattern and fuzzy matching with TF-IDF scoring.
03
Review & approve
Triage by match type with bulk actions and explainable chips.
04
Export 301s
Download deploy-ready redirect rules in CSV or JSON.

Use cases
URL redirect mapping for every migration type
01
Replatforming
Moving from one CMS to another with completely new URL structures — without dropping a single ranking page.
The biggest risk in any replatform isn't the build — it's the redirect map. We turn 80 hours of mapping into an afternoon.
Magento → Shopify — category & product flows
WordPress → Headless — slug normalization
Custom CMS migrations — any source format
Bulk auto-accept — 92%+ confident matches
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
Reorganizing URL hierarchy, renaming categories or normalizing slugs — without breaking link equity.
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
