How do you handle BigCommerce nested category URLs on Shopify?
While Shopify serves collections at flat `/collections/{handle}` paths, we preserve your full parent-to-child category hierarchy in visual breadcrumbs, `BreadcrumbList` JSON-LD, and navigation, while mapping every legacy nested BigCommerce category URL to its exact Shopify collection in a single 301 hop.
