Brand Field

A brand is defined as the supplier of goods or services. Normally, a brand will sell the products or services to another company or individual. Brand Field is provided only in the Matching Column section for Add feed in Wix. 

The Static Value is when you want to apply the same value to all the products in the feed. You can do this by selecting the option as static and entering the value in the field instead of entering the column index or name. 

For example:

So, all the products will be imported as BrandA.
