Follow these guidelines to make sure you submit high-quality data for your products and get the best performance from your ads.

Minimum requirements

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

  • Don't provide more than 2 digits after a decimal. If you include more than 2 digits after the decimal, they'll automatically be rounded to the nearest acceptable value. For example, 1.0234 will be rounded to 1.02 and 29.8999 will be rounded to 29.90.

Best practices

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

  • Use the same type of units as you used for unit_pricing_measure. For example, if you use sqm for unit_pricing_measure, then use sqm for 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 the Diagnostics page of your Merchant Center account.

United Kingdom only
  • Submit metric values when targeting the UK. The imperial units (e.g., floz, pt, qt, gal) are interpreted as US imperial units, which are different than the imperial units used in the UK.
