A marketing consultant works to further the brand, image, and market share of the company for which they work. This can include a wide variety of activities. For example, one day, a marketing consultant may be helping their company improve its brand image among users of a certain social media outlet such as Facebook or Twitter. The next day, they may work with designers to put together a brochure or complete a marketing package to help land new customers. For this reason, the ability to work cooperatively with others is one of the most important skills a marketing consultant can have.

Marketing consultants generally work in an office environment, and their work tends to be more mental than physical. They often spend a great deal of time on the telephone, helping to coordinate efforts among different departments, such as legal and design. They are also generally responsible for being able to identify and quantify the results of various marketing campaigns or projects.
