Technical SEO utility
Redirect Mapping Validator
Validate redirect mapping CSV files before implementation. This checks the mapping itself; it does not send requests to the live URLs.
Redirect Mapping Validator
Upload a CSV redirect map to identify duplicate source URLs, missing or malformed values, self-redirects, redirect chains, and loops before implementation.
Expected CSV format
Use a header row with source and target. Both columns should contain absolute URLs, including http:// or https://.
source,target
https://example.com/old,https://example.com/new
https://example.com/legacy,https://example.com/currentChecks are performed in your browser. Your CSV is not transmitted.
Validation results
| Row | Source URL | Target URL | Result | Findings |
|---|
This is a mapping-file validator, not a live HTTP crawler. Redirect chains are detected only when the destination also appears as a unique source in the uploaded CSV.
