Shopify catalog architecture and faceted navigation control
Shopify by default creates duplicate product URLs within collection subfolders (/collections/apparel/products/item-name) alongside the canonical root URL (/products/item-name). Left unaddressed, internal linking dilutes product authority and burns search engine crawl budget.
We rewrite liquid theme templates to enforce canonical internal links sitewide. Furthermore, we configure strict canonicalization and noindex robots rules on dynamic faceted filters (colors, sizes, price ranges) to eliminate infinite crawl traps while preserving search-friendly subcategory pages.
