Logos are often misunderstood.
Your logo is your brands face, but not the whole body. Your brand has a visual identity and your logo is one part of that identity.
Your logo is the simplest and quickest way in which people will recognize and know your brand.
A logo’s has a big job to do: it needs to deliver a message, convey feelings and be remembered. Because a logo needs to complete such a huge task and is often only seen for seconds at a time, it needs to be as simple as possible while still being unique enough to be recognized.
Logos do not need to tell people about every product you sell or service you offer. This makes the logo far too busy and therefore not easy to recognize or remember.
