Best practices

These best practices can help you go beyond the basic requirements to optimize your product data for performance.

  • Match the manufacturer’s sizing of the product. If your product already has a size type on it, then submit the matching supported value.
  • To represent products with two size types (for example, "big and tall" or "petite maternity") submit two matching values.
  • Submit the size type whenever it’s relevant. If you don’t include a size type, we’ll use regular as the default. If that’s not the right size type, then users could be misled, which could affect your sales.
  • Submit the size_system attribute. To also explain which country’s sizing system your product uses, also submit the size_system attribute.
  • Submit the size attribute. Along with the size type, make sure to submit the specific size of your product using the size attribute.
  • Submit the gender attribute. To help show your product in the right search results, also submit the gender attribute.
