Unit pricing base measure [unit_pricing_base_measure]

The unit pricing base measure [unit_pricing_base_measure] attribute lets you show how the price of your product translates per the indicated unit. For example, if you were selling a 150 ml bottle of perfume, you could show customers how much your perfume costs per 100 ml.

Minimum requirements

These are the requirements you'll need to meet to show your product. If you don't follow these requirements, we'll disapprove your product and let you know in your Merchant Center account.

  • Submit the unit pricing measure attribute to define the measure and dimension of your product. For example, if you submit 3 USD as the value for the price [price] attribute, 150 floz as the value for the unit pricing measure [unit_pricing_measure] attribute, and 100 floz as the value for the unit pricing base measure [unit_pricing_base_measure] attribute, the unit price would be 2 USD for every 100 floz.

Best practices

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

  • Use the same type of units for this attribute as you use for unit pricing measure. For example, if you use sqm for the unit pricing measure, then also use sqm for the unit pricing base measure.

Additional guidelines

Review each section closely to determine if the requirements apply to your country or product. If you don't follow requirements that apply to you, we'll disapprove your product and let you know in your Merchant Center account.
