Redirect Mapping Checker
Upload or paste a migration mapping CSV to validate old URLs against expected new URLs. Find incorrect redirects, redirect chains, non-200 landing pages, request errors, and final URL mismatches before they affect users or search engines.
CSV
old_url + new_url
Bulk
Migration validation
QA
Chains, 200s, errors
Built for bulk migration mapping checks, not single-URL guesswork.
Validate old-to-new URL mapping rows, compare expected destinations with observed final URLs, and control the rules that affect migration QA decisions.
Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.
Upload migration mappings
Upload a CSV with old_url and new_url columns, or paste mapping rows directly for smaller checks.
Compare expected vs observed URLs
Check whether each old URL lands on the expected final destination from your mapping file.
Flag chains and non-200 landings
Identify multi-hop redirects and final URLs that do not return a clean 200 response when validation is enabled.
Control URL matching rules
Treat trailing slash variants as equivalent, ignore query parameters, set max hops, and classify request failures.
Migration traffic can disappear when redirects land on the wrong final URL.
A good redirect mapping process confirms the old URL redirects, the final destination matches the expected new URL, and the landing page returns a clean response. Wranker keeps that workflow focused for SEO teams, agencies, and developers.
Reduce migration risk
Validate redirect mappings before and after launch so important old URLs do not land on the wrong pages.
Find incorrect redirects faster
Compare expected new URLs against observed final URLs at scale instead of checking migration rows manually.
Improve technical SEO QA
Detect redirect chains, non-200 final pages, invalid URLs, and failed requests in one focused workflow.
From mapping CSV to redirect QA workflow in four clear steps.
The landing page stays focused on the input. After you submit, Wranker handles result tabs, row evidence, raw data, export options, and reporting output inside the app.
Upload or paste your mapping CSV
Add a CSV with old_url and new_url columns using file upload or Paste CSV mode.
Configure validation rules
Choose redirect following, final 200 checks, trailing slash handling, parameter matching, hops, timeout, and advanced options.
Run the redirect check
Wranker validates each old URL and follows redirects based on the settings you selected.
Review results in Wranker
Use result tabs, row-level evidence, raw data, exports, and Download Report inside the output experience.
Practical migration QA for teams that need redirect evidence quickly.
Use the checker before launch, after deployment, during domain moves, and when agencies or developers need clear issue evidence.
Pre-migration QA
Validate planned mapping rules before they go live so incorrect redirect targets can be fixed early.
Post-migration validation
Confirm old URLs redirect to the right new URLs after launch and prioritise failed mappings quickly.
Domain and URL structure changes
Review old-domain to new-domain redirects plus product, category, collection, blog, and landing page mappings.
Client reporting and implementation QA
Share redirect issues, final URL evidence, and practical fix details with clients or development teams.
Continue your migration and technical SEO workflow.
Pair bulk mapping validation with single-URL redirect diagnostics, response code checks, broken link review, and broader migration QA tools.
URL Redirection Path Checker
Run deeper single-URL redirect and header diagnostics when one mapping needs detailed inspection.
OpenRedirection Finder
Discover domain-level redirect behaviour before building or validating migration mapping rules.
OpenHTTP Status Code Checker
Verify response codes across URLs and inspect status problems found during migration QA.
OpenBroken Link Checker
Find broken internal or external links after migration and clean up non-200 landing paths.
Questions about redirect mapping checks.
Clear answers about live URL validation, CSV columns, incorrect redirects, chains, non-200 landings, URL parameters, trailing slashes, and download-ready results.
A Redirect Mapping Checker validates old-to-new URL mappings and checks whether old URLs redirect to the expected final destinations.
Yes. The tool is designed to validate live HTTP or HTTPS URLs. It should not be described as checking staging, private, or password-protected URLs unless that functionality is confirmed.
The CSV must include old_url and new_url columns. Each row should contain the old URL and its expected new destination.
Yes. You can paste CSV content directly into the Paste CSV tab.
An incorrect redirect happens when the observed final URL does not match the expected new URL in the mapping file.
A redirect chain happens when an old URL goes through multiple redirect hops before reaching the final URL.
A clean migration redirect should usually land on an accessible page that returns HTTP 200. Non-200 landings should be reviewed and fixed.
Yes. The tool includes a setting to ignore query strings when comparing expected and final URLs.
Yes. The tool can treat /page and /page/ as equivalent during comparison.
Yes. Use Download Report when you need to share redirect mapping results with developers, clients, or SEO reviewers.
Validate your redirect mapping before migration issues cost traffic
Upload or paste your migration CSV to check old URLs against expected new URLs, find incorrect redirects, detect chains, flag non-200 landings, and review errors.
Use the results for migration QA, developer handoff, client reporting, and post-launch SEO checks.
