A brand is collectively, the terms, symbols and products that differentiate one product, service or company from another. Companies will often be referred to as brands.

Branded products or content refers to output from the company that is explicitly marketed as being that brand's product or service. Coca-Cola is a famous example of using the brand to market a product.

Affiliate marketing is a program wherein third-party individuals or websites (affiliates) generate traffic or leads to a particular product, company or service. These affiliates then get revenue from leads or sales generated by their efforts.

This is common in influencer marketing, for instance, where an image or video will link to certain products, and the influencer will receive a small portion of any sales made from the link they provide. Certain industries will have opt-in programs as well, such as photography sites that provide affiliate links to the gear they use in exchange for revenue from the companies who benefit.
