About the GSC 404 to Redirect Matcher
The GSC 404 → Redirect Matcher is a free tool that maps your Google Search Console 404s to the best live replacement URL, so you can turn dead pages into 301 redirects that recover lost traffic. Paste your 404 list and your live URLs, and it scores every match on your device.
What it does
- Accepts a raw 404 list or a Search Console / Shopify export
- Matches each dead URL to your live URLs by slug and title similarity (character-bigram Dice)
- Ranks matches by a confidence score with an adjustable minimum threshold
- Exports ready-to-use 301 redirect rules for the matches you keep
Why we built it
When ranking pages start returning 404, their traffic and authority evaporate, and finding the right live replacement for each one by hand is slow. This tool does the matching deterministically — the same relevance engine from Novatise — so you can close the loop fast.
Who it is for
SEOs and site owners recovering from a migration, re-platforming or content prune that left ranking URLs returning 404 or 410.
Frequently asked questions
Where do I get my 404 list?
From Google Search Console (Pages report, Not found 404) or your server logs. You can paste the raw list or a CSV export.
How does the matching work?
It compares each dead URL's slug against your live URLs' slugs and titles using character-bigram Dice similarity, then returns the highest-scoring match above your confidence threshold.
Does it check whether the pages really 404?
No. This offline matcher focuses on suggesting redirect targets and trusts the list you provide, so nothing is fetched or changed.
