Consumers often search and compare products by unique identifiers such as EAN’s, MPN’s and UPC’s, thus it is vital to include these if they exist.

Failing to feature these will give your competitors an advantage and may even prevent your items appearing on certain partners, in certain countries. The inclusion of unique product identifiers is most crucial for branded and hard goods such as electronics / appliances, which are regularly compared via price comparison sites.

Retailers of older/ custom goods that don’t have a unique product identifiers can use the “identifier exists” attribute to inform certain partners (such as Google).
