# Shopify Redirect Mapping Turn a list of 404ing URLs into live 301 redirects on a Shopify store using type-aware fuzzy matching with a manual review queue for the leftovers. The job is reclaiming search equity and rescuing lost visitors, not building a perfect 1:1 map. For bulk apply through a spreadsheet instead of the API, hand the final map to the sibling `shopify-matrixify` skill's Redirects sheet. ## The one rule that matters: recall over precision A wrong-but-related redirect beats a 404. A visitor who lands on a close product or the right category still converts; a visitor who hits a dead page leaves. Google keeps some of the old page's equity when the 301 points somewhere topical; it keeps none when the URL 404s. So tune for coverage, not for a flawless match, and let a human review pass catch the misfires. **Worked case (an automotive-lifestyle brand, anonymized).** A first pass used a single conservative 0.92 similarity threshold across all URL types. Out of 1,010 dead URLs it produced 6 redirects: effectively nothing, and the merchant called it useless. Re-running with per-type thresholds plus cross-type fallbacks yielded 725 live redirects (~72% coverage) from the same export. The lesson is blunt: do not ship a conservative first pass. Precision-first thresholds look safe and deliver nothing. ## Per-type thresholds (defaults, not suggestions) Different URL types tolerate different looseness. Classify each dead path by its prefix, then match it only against ...
