A local-first Python tool that prevents lost traffic and Google rankings when products are discontinued. When you unpublish out-of-stock items, it generates clean 301 redirect mappings pointing visitors and search bots to the closest relevant category or parent product, complete with cyclic redirect loop protection.
List of discontinued product URLs or Shopify export with status=draft/archived.
Local Python script validates URL targets, prevents redirect chains/loops, and generates 301 rules.
shopify_redirects.csv (ready to import in Shopify Navigation) and nginx_redirects.conf.
Setup scope covers installation on customer-controlled infrastructure, configuration of authorised integrations, functional testing and handover.
Hosting, third-party charges and ongoing support are excluded unless separately agreed. Free workflows must never run on Sanocea-hosted infrastructure.
Unpublishing out-of-season or sold-out products creates broken 404 links across Google Search and ad campaigns, causing high bounce rates and lost sales.
404 errors destroy SEO domain authority and waste paid ad clicks when shoppers land on dead pages instead of live inventory.
Takes a list of discontinued product URLs, maps each to its parent category or store collection fallback, detects and prevents redirect loops, and generates import-ready redirect files.
Shoppers clicking old links land seamlessly on related in-stock collections, turning dead pages into revenue.
Shows how discontinued variant URLs are mapped to valid collection pages without manual spreadsheet work.

For technical teams or developers assisting your business, below is the visual execution architecture and automated verification breakdown:
The script evaluates catalog variants CSV exports, resolves fallback destinations to parent products or collections, prevents circular loops, flattens multi-hop redirect chains, and outputs Shopify CSV, Nginx, Apache, and Cloudflare rules. Zero external network calls are made.
Outputs native Shopify Admin import CSV, Nginx server map, Apache .htaccess, and Cloudflare _redirects
Detects circular redirect cycles (A ➔ B ➔ A) and self-redirects, routing safely to collection fallbacks
Collapses multi-hop paths (A ➔ B ➔ C) directly to single-hop (A ➔ C) to optimize crawl budget

The generator tracks the forward redirect graph before generating rules. If a cyclic relationship is detected (such as A pointing to B and B pointing back to A), it breaks the cycle by safely routing the request to a default category or store collection fallback.
Yes. It produces a compliant shopify_redirects.csv with exact 'Redirect from,Redirect to' columns that you can upload directly via Shopify Admin under Online Store > Navigation > URL Redirects > Import.
A redirect chain occurs when URL A redirects to B, and B redirects to C. Search engines penalize multi-hop chains because they waste crawl budget and slow page load times. This engine collapses intermediate hops directly so URL A resolves immediately to C in a single 301 response.
Yes. In addition to CSV imports, it generates an nginx_redirects.conf map block, Apache .htaccess rewrite rules, and Cloudflare _redirects files for sub-millisecond edge routing.
How unpublishing discontinued product variants creates 404 errors that drain organic search traffic, why redirect loops destroy crawl budgets, and how automated rule generators preserve ranking.
