A coherent marketing mix refers to the strategic combination of various elements that a company utilizes to promote and sell its products or services. These elements, also known as the 4Ps of marketing, include product, price, place, and promotion. A successful marketing mix is one that is carefully planned and executed, with each element complementing and reinforcing the others to create a cohesive and effective marketing strategy. It is essential for businesses to have a coherent marketing mix in order to reach their target audience, differentiate themselves from competitors, and ultimately drive sales and revenue.
