This essay sheds light on how to become a marketing manager, explicates how to be highly successful as a marketing manager, and elucidates how to earn revenue as a marketing manager. While becoming a marketing manager may seem be an eminently cumbersome, expensive, time-consuming, and daunting undertaking, it is viably possible to become a marketing manager. Much to the relief of prospective marketing managers, it is possible to become a marketing manager in a time span of less than half of a decade and the journey to become a marketing manager is not as lengthy as the journey to pursue certain other occupations, such as the occupations of a medical doctor or attorney. The pathway that a prospective marketing manager can follow to become a marketing manager is fraught with challenges that are not a cinch to surmount. It can be arduous to fulfill the duties of a marketing manager. Marketing manager skills are highly desirable skills to possess. As of December of 2020, only an infinitesimal fraction of one percent of the global population are employed as marketing managers in the U.S., for instance, less than 532,000 are employed as marketing managers even though the U.S. population is comprised of over 328,000,000 people as of December of 2020. As of December of 2020, less than .162% of people in the U.S. are employed as marketing managers. This means that out of 617 random people in the U.S., about only one person at most would be employed as a marketing manager as of December of 2020. As of December of 2020, it was estimated that there were more medical doctors and attorneys as an aggregate in the U.S. than marketing managers in the U.S. even though it takes far more years to fulfill the ample mandatory requirements to become a medical doctor or attorney than it takes to fulfill the mandatory requirements to become a marketing manager. As of December of 2020, there are no mandatory requirements that need to be fulfilled for a person to become a marketing manager. As of December of 2020, the economy is unequivocally in dire need of more marketing managers, especially since they are able to help companies to optimize their marketing campaigns. Having subpar marketing campaigns amplifies a company’s marketing costs. Neglecting to optimize its marketing campaigns can undermine a company’s profitability potential. Companies should aim to eliminate unprofitable elements from their marketing campaigns. Having unprofitable elements in their marketing campaigns can cause companies to imprudently hemorrhage marketing dollars. A marketing manager’s role extends beyond the ambit of overseeing the marketing campaigns of their clients. A marketing manager should aim to optimize the marketing campaigns of their clients and render the marketing campaigns of their clients devoid of unprofitable elements. It is of eminent importance that marketing managers are constantly refining the marketing campaigns of their clients based on the insights that they gleaned from meticulously analyzing customer-driven analytical data so that the marketing campaigns of their clients cannot only become more cost-effective marketing campaigns, but can also become devoid of unprofitable elements. Marketing managers can utilize metrics that measure the effectiveness of a marketing campaign so that they can gain insights into determining which elements of a marketing campaign are in dire need of being enhanced and which elements are in dire need of being jettison from a marketing campaign. When marketing managers neglect to meticulously analyze customer-driven analytical data and subsequently ameliorate the marketing campaigns of their clients, then they are hemorrhaging the marketing dollars of their clients, not optimizing the marketing campaigns of their clients, and are ultimately abating the efficacy of the marketing campaigns of their clients. The overall goal of a marketing campaign should be not only to yield a high “return on marketing dollars investment, a high product sales conversion rate, a high product sales growth rate, a high customer growth rate, a low customer acquisition cost”, and sizeable sales revenue, but should also be able to help a company to be able to grow its lucrative customer base, amplify its positive brand recognition, cultivate its brand equity, and bolster its brand image.
