Based on the existing risks, a feasibility study estimates the viability of planned projects. A viability check examines whether a project or business is implementable and, more importantly, whether it is economically viable. Is it possible to create a financial safety net? Is there enough personal capital? and how far will cost risks have a negative impact on the project in the future? In online marketing, feasibility studies will be used to determine which projects should be implemented. For example, if a company is thinking about using more expensive URLs, it can conduct a feasibility study to determine the potential value of the URLs and how to monetarize them. Pre-investment studies are also important in e-commerce.
