Logotype is an emblem or a symbol of a company. In web design logotypes are a part of website graphics. Logotypes are used as a part of corporate image, usually on websites, signboards, business cards and other printed documents. A logotype can consist of letters, words, shapes, as well as any other graphical characters.

A good logotype is easy to understand, recognize and remember. Besides that, a good logotype illustrates the area of business activity, helping potential clients to intuitively find the company they need. Comparing to corporate colours and mottos, a logotype is easier to recognise, which is why they are considered to be the main part of a corporate style.
