When should I split one product into multiple Shopify listings?

Split a product into separate Shopify listings when the versions need meaningfully different positioning, content, imagery, collections, SEO targeting or merchandising. Keep them as variants when the shopper is choosing a configuration of the same underlying item. Before splitting, consider the effect on reviews, inventory, URLs, analytics and feeds. A good rule is to model the catalogue around how customers think about the products, not simply around how the source system stores them.
