A friend of his drops by the table and tells the woman how wonderful the man is, how intelligent he finds him and how impressed he has been with the man's recent accomplishments. That's public relations.
If the young many asks the woman about her opinions and interests, shows how interested he is in her conversation, and says how intelligent he finds her and how impressed he has been with her recent accomplishments, that's marketing.
Marketing is a process that identifies, anticipates and satisfies your customers needs and desires so your business profits. It involves planning and implementing the idea, pricing, promotion and distribution of goods and services. It includes an exchange that satisfies customer and organizational goals. A marketing strategy is driven by customer desires and is directed to the customer. Marketers ask: Who are our customers? What do they think, believe and want? What has value to them, and how do we deliver that value? The goal of marketing is to respond to the customer and meet their needs.
Public relations is a function that helps an organization manage its reputation. The public relations function provides strategic advice on how an organization should communicate. It may develop, or simply approve, anything that goes out to the public in order to ensure consistency and compliance with the overall corporate objectives. They don’t develop the polices or services, but they help ensure that customers understand what the organization has to offer and what it does for the community. It not only puts out fires, it provides counsel to help an organization avoid those fires. A public relations strategy is driven by organizational desires and is directed at a number of publics, often through the media. PR practitioners want to know: How does the public feel about us? How do we look and what do they think of us? How do we want them to see us? The goal of public relations is to promote a positive image about an organization.
Promotion is getting the word out about your product or service. It may involve any number of channels (such as web, email, word of mouth, or social media). The goal of promotion is to raise awareness.
Often, particularly in smaller organizations, all of these functions are the responsibility of one person, and that person may have other responsibilities as well.
A marketing strategy will include elements of public relations and promotion. It is crucial to successful and sustained delivery of your product or service.
