Branding

A well created logo is the most important part of establishing your brand.  It should convey your style and it should be memorable.  You can't expect to establish your brand and become a memorable business if you keep changing your logo up.  You must establish a logo and stick with it until you have established yourself.  

Good logos are generally limited to two colors, and can be translated easily into black and white.  Colors are very important and psychologically affect how people perceive your business.  I will provide information on what different colors convey, and what colors are recommended for best results.  

Your logo design can't be too busy as most people have a very short attention span - about 3 secs.  It should convey your message and be memorable enough that people can remember the main details if they go to look you up. 

The only reason to change up your logo is if your branding approach is not doing well, and you are trying to find your footing and get people's attention before going under.  Reestablishing one's self is easier said than done, so it is better to take the time and settle on a logo that will be truly memorable.
