In today's fast-paced world, it is more important than ever to promote recognition of a product or service. If you're remembered as a quality provider, then you will be encouraging repeat business.
Branding is a great way to promote this recognition because people are busy and tend to adhere to familiarity. If consumers recognize a brand that they have previously used and they remember being satisfied with it, then they are more than likely to choose that product or service again. This is especially true in the tremendous hodgepodge of advertising.
