Best practices

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

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