What is the importance of Advertising in the process of sales and business development?

The heart of your business success lies in its marketing. Most aspects of your business depend on successful marketing. The overall marketing umbrella covers advertising, public relations, promotions and sales. Marketing is a process by which a product or service is introduced and promoted to potential customers. Without marketing, your business may offer the best products or services in your industry, but none of your potential customers would know about it. Without marketing, sales may crash and companies may have to close.
