Marketing is how a business introduces the world to their brand or products by appealing to a specific pain point and convincing the potential buyer that their product or service is the answer they need. In practice, it includes everything from market research to branding to social media and any other form of advertising.
Essentially it is a huge blanket term that describes any of the steps a business takes to promote and sell its products and/or services to potential buyers. Especially as a home-based business, it is essential to find the best way to promote your business consistently. The internet has become every small-business owner's friend by giving access beyond the local community but to the entire world without a multi-million dollar budget.
