Buyer Persona is a description of your ideal customer base that is derived from market research and real data on your current customers. If you offer more than one product or service it is typical to have more than one persona.
When creating a buyer persona take into account demographics, behavior patterns, goals, motivations, education level, career title, income level, age, gender, and anything else that you find typical of your customers.
Developing buyer personas are vital to target marketing. The personas tell you exactly who your customers typically are which allows better-targeted advertisements, sales, and promotions.
