How do I create a default brand in my feed?

If your products are all the same brand (example: Your Brand) and you want to define this in your feed without updating each product one by one, in the advanced commands area type:

For Google:

setAttributeDefault brand as “Your Brand”
mapAttribute brand to g:brand

For Amazon:

deleteAttribute band
setAttributeDefault brand as “Your Brand”
mapAttribute brand to brand
setParam localized_name “Brand Name”

Replace “Your Brand” with the brand/vendor name.
Keep “Brand Name” as is, as it is Amazon’s required local label for the brand field.

For other merchants:

setAttributeDefault brand as “Your Brand”
mapAttribute brand to [merchant-brand-attribute-name]

Replace [merchant-brand-attribute-name] with the target’s attribute brand name. For example, Bing’s brand attribute name is simply: Brand
