Textual logos are simple text used in a logo format. The font type can appear in various shapes and sizes to convey your message. A thick font conveys your business’ power or strength; a fancy script font conveys style and elegance. A good example of a textual logo featured below.

Icons and symbols use imagery that conveys a literal or abstract representation of your organization. Symbols are less direct than straight text, leaving room for broader interpretation of what the organization represents.
A good example of a Iconic/Symbolic logo would be Apple or Volkswagen Logos.
