Good writers can deliver great work on a wide variety of topics, but it is also often true that an individual writer will do their best work for a particular industry segment or type of product. Indeed, some writers and copywriters will deliberately specialize in health care, finance, B2B or some other niche area. So ask a writer which areas of business he or she is most familiar with.
