Guidelines

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

Minimum requirements

These are the requirements that 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 on the Diagnostics page of your Merchant Center account. 

  • There are no minimum requirements for this attribute. Keep in mind that you still need to follow the formatting guidelines or the information that you submit can't be used.

Best practices

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

  • Submit the size system for all clothing products. By submitting your product's size system, you can help ensure that the size is shown correctly in your ad.
  • Submit the correct system for each product. If you have different products each with different size systems, make sure to submit the correct size system. If you don't submit a size system, we'll use the standard system for your target country, which might not be right for your product.
  • Submit the size [size] attribute. Along with the size system, make sure to submit the specific size of your product using the size [size] attribute.
  • Submit the size_type [size_type] attribute if relevant. If your product also has a size type, submit the size_type [size_type] attribute.
  • Submit the gender [gender] attribute if relevant. To help show your ad for the right search results, also submit the gender [gender] attribute.
