How to build an online business
Solve a customer problem.
Consumers buy products and services to satisfy a physical or emotional need. However, customers only buy when the need is paramount in their mind.
For example, a homeowner will hire a plumber if he has a leak, men and women will buy new clothes to enhance their appearance, or a student will take special lessons if he believes completion will lead to a better job. Your online business product or service must stimulate and then fulfill that need before a sale occurs.
