Define user roles according for: affiliates, sales agents, bloggers, sponsors or suppliers.
User roles are an important factor when considering how different aspects of a business work together. User roles can be defined as affiliates (people who promote products or services), sales agents (people responsible for negotiating and signing contracts), bloggers (people who write about products or services to inform the public or solicit the purchase of something), sponsors (companies that typically fund a certain event or activity for marketing purposes) and suppliers (people who provide goods and services to companies).
Each of these user roles is important when done correctly, as it helps to maintain the flow of operations of any business.
