• Submit one of the supported values whenever required for your category and target country.
• Use this attribute for all products that vary by age group.
• If your product is not exclusively for children, set the value to adult. This does not limit eligibility or imply explicit content.
• Submit accurate values even if the product is not technically a variant, to ensure inclusion in filtered searches.
• Pair with the gender attribute where applicable for more precise variant targeting.

SEO Tip

Accurate age group values improve the match between your product and relevant search filters, helping users find the right size or variant quickly. When paired with gender and size, this can significantly improve conversion rates.
