Ghostwriters are hired for numerous reasons. In many cases, celebrities or public figures do not have the time, discipline, or writing skills to write and research a several-hundred page autobiography or "how-to" book. Even if a celebrity or public figure has the writing skills to pen a short article, they may not know how to structure and edit a several-hundred page book so that it is captivating and well-paced. In other cases, publishers use ghostwriters to increase the number of books that can be published each year under the name of well-known, highly marketable authors. Usually, there is a confidentiality clause in the contract between the ghostwriter and the credited author that obligates the former to remain anonymous.
Also, ghostwriters may work on accompanying documents, such as treatments for screenplays. Often, ghostwriters will work on related projects beyond the scope of professional ghostwriting, such as marketing, promotions, sales, publishing or other related services for pay, in order to procure more clients and increase the total amount of their business.
