According to Wikipedia, a logo is a graphic mark, emblem, or symbol used to aid and promote public recognition. It may be of an abstract or figurative design or include the text of the name it represents as in a logotype or wordmark.
No matter how old or young a business is in age, a logo will always be a very powerful tool for every business. It can be of a very small size, but yet it always portrays lot about the business and it is often times the first thing customers recognize and use in differentiating a brand from another.
In this piece of write-up, I have compiled and discussed some few signs that may be a good indicator that your business/company logo needs a refresh.
