From my experience as a logo designer, I have conclusion there are 3 kind of logo type:
1. The logo represent for your vision mission.
2. The logo represent for your branding name.
3. The logo represent for your product.
Most of us think a logo is just simple thing. However logo actually is very essential in today business if you could understand the real hidden strength of a logo. Logo is a graphical element that its logotype could form a trademark and commercial brand. It will give a silence message to the management of a company. It also speaks to it’s customer about the company and products or services. Brand image is so essential in business which often the success of a product depends solely on it.
