'''[[w:Market research|Market research]]''' is any organized effort to gather information about [[w:target markets|target markets]] or customers. It is a very important component of [[w:business strategy|business strategy]]. The term is commonly interchanged with [[w:marketing research|marketing research]]; however, expert practitioners may wish to draw a distinction, in that ''marketing'' research is concerned specifically about marketing processes, while ''market'' research is concerned specifically with markets.
