Guidelines

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. 

• Use a standard size value for your target country. Learn more about what types of values are recognized
• Submit only one attribute per item. If you provide multiple size attributes for the same item, only the first will be applied. Additional size attributes will be discarded, and you will receive a warning.
• Submit only the size value. Don’t submit values such as n/a, none, or multisize. Make sure to submit non-size information through the correct attribute such as color, material, and pattern.
• Submit size for all products that vary by size. 
  • For apparel products, use this attribute when your product is a variant that’s distinguished by its size. For example, small red T-shirt and large red T-shirt. Also submit each variant as a separate product with the same value for the item_group_id attribute. Don’t submit multiple sizes separated by a comma ( , ). Instead, use a slash. For example, enter small/medium/large (and not small, medium, large).
  • For non-apparel products, submit the relevant size. Sizes for these types of products vary widely, but providing this information can help ensure that your product is shown to the right users.
• Condense multiple dimensions into one size value if your product uses multiple dimensions. For example, use the size 16/34 to represent neck size 16 inches and sleeve length 34 inches.

Best practices

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

• Provide values that your users will understand. The values that you provide could be shown to users, so make sure that values you submit can be understood by your users.
• Use a consistent format for size. For example, imagine you’re advertising a shirt that comes in small, medium, and large. For those variants, submit S, M, and L. Don’t submit S, Medium, and Lrg. The size that you submit is standardized before it’s shown to users. By submitting consistent sizes, you can help ensure that the size is standardized correctly. 
• Provide more size details using the other size attributes. Provide the cut of your garment using size_type. Indicate the country convention for your size with size_system. 
• Submit the complete size of your product. If your product size has several components, make sure to submit all of this information. Otherwise, the size could be misunderstood, and it might not be standardized or shown to the correct users. For example, if you sell shoes in different widths, you should specify the width in the size attribute. So, instead of just submitting size 8, you'd submit size 8 W to represent 8 wide.
• For merchant-defined multipack products, please submit the multipack quantity using the multipack attribute. Do not submit the multipack quantity under size.  

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.
