An advertising account manager works at an ad agency and acts as a liaison between the agency’s clients and its creative departments. As an advertising account manager, your duties include developing effective relationships with potential clients and pitching the agency’s marketing services to boost business. You also oversee the management of ad projects and ensure the delivery of creative work and other relevant information for each account in your portfolio. Another aspect of your job involves securing deep advertising reach for your clients, such as negotiating the purchase of TV ad time and advertisement space in magazines, newspapers, and websites.
