More and more businesses understand the importance of promoting the image of their products and services. Therefore expenditure on advertising has grown tremendously over the last few decades. A crucial aspect for marketers is that advertising should be unique. Marketers who simply imitate existing products may find themselves advertising more for their competitors than for themselves.

Consumers need to see and feel the benefit of using the product and that's where advertising comes in. They generally have a flavour for learning about the product from what they see on posters or TV ads. Consumers often prefer clear product shots and also want to learn how to use the product. The ad needs to be informative in order to be motivating and convincing. In a nutshell, the essence is to let consumers see how good the product is.

Some companies resort to external advertising agencies which provide a professional service. They help companies decide how to structure advertising and focus on their potential clients. They use a number of different marketing tools including TV, newspapers, magazines and commercial web sites. The cost of promoting products or services online can sometimes be higher, particularly when on-line buyers require sellers to provide an extra level of service.
