Logo designs are typically a visual representation of a graphic or text or a combination of both that provides a unique identity to a company and its products. Logos help to create a visual recognizable identity for a company that effectively contributes to the company's branding.
With the wide artistic possibilities, logo designers often become too enthusiast in creating a company logo design that actually fails to meet the purpose. An extremely abstract art, or a very complex illustration is often not a good example of a logo though they might be considered as a good art if considered from the perspective of a general artwork and not a logo. A logo design should be well thought out, with factors like usage, application and the nature of the company being kept in mind. These few simple tips will give you a grip on the job and even when you get a professional logo design firm to do your logo, you will know what exactly to ask from them.
