Field Marketing is the act of providing services to people within their immediate location. It’s valuable because it can be more effective than other forms of marketing in interacting with customers and prospects on-site. It means that people can touch or try what you’re selling before they buy it! However, Field Marketing also has its downsides. For one, it’s expensive to maintain a staff of Field Marketing representatives. And another downside is that some products just can’t be sold through this type of approach.
