A marketplace is an area for people to come together to purchase and sell goods and services in the physical sense. In a digital sense, it's an online space where buyers and sellers engage in trade. Understanding marketplaces is the first step to fully grasping how to take charge of a market. It's almost impossible to gain mastery of the marketplace without first learning what it is and how it works.

Many large corporations perform business activities in an online marketplace. The best part about an online marketplace is that restrictions do not usually affect the vendors. A marketplace doesn't interfere much with the transactions that occur on a company's website, meaning there's more freedom and speed in trading on the site.
