A logo has multiple functions to do in an organization, a few of which are quoted as below:
One major function of a logo is that it is the identity of your business, over time, when the brand gains popularity, the customers start associating a particular design of a logo with the brand.
The brand value associated with a particular logo of a company stirs the thought process of the consumer and greatly influences the decisions and choices of the consumer when making the purchase.
Evokes emotional response:
A mere look at a particular logo revives the past experiences and good or bad memories that a consumer has had with a particular brand. This builds up consumer loyalty and makes your consumers understand the value system of the company and sensitivity towards qualitative aspects.
A logo, apart from making things differential, also aids the brand to deliver an additional message that carries a meaning which indeed makes the objectives of the company clearer for the normal consumer.
Reflects your business:
The brand name and logo are two major factors that tell the consumer mostly everything about your business; your sector of dealings and the range of products/services that you work with.
