A good logo is distinctive, appropriate, practical, graphic and simple in form, and it conveys the owner’s intended message. A concept or “meaning” is usually behind an effective logo, 
and it communicates the intended message.

 A logo should be able to be printed at any size and, in most cases, be effective without color. A great logo essentially boils down to two things: great concept and great execution.

5 Principles Of Effective Logo Design:
  • Simple : Simplicity makes a logo design easily recognizable, versatile and memorable.
  • Memorable : An effective logo design should be memorable, which is achieved by keeping it simple yet appropriate.
  • Timeless : An effective logo should be timeless. Will yours stand the test of time? Will it still be effective in 10, 20 or 50 years?
  • Versatile : logos should be designed in vector format, to ensure that they scale to any size.
  • Appropriate : the logo should be appropriate for its intended audience.
