Definition: Unique Selling Proposition or USP is the one feature or the perceived benefit of a good which makes it unique from the rest of the competing brands in the market. It is that very reason which motivates a buyer to purchase that product even though it might be costlier than other products. Description: Unique Selling Proposition or USP is a very important concept used during the time when a company promotes its product through its advertisements in both TV as well as print media which eventually attracts a consumer to buy a particular product. The key to boost the sales of the product effectively through advertising is to highlight the USP of the product prominently. Unless you highlight the USP, consumers will not be tempted to buy your product. Every product should have its own USP, which makes it stand apart from other products in the similar category. USP is different for different products. Let’s take an example of a restaurant which is very famous across the world for its quick Subway Sandwiches. The company makes the sandwiches healthier for consumers. Consumers who are looking for a quick meal can walk into any subway outlet and get a quick sandwich made, which contains nutritional value. In this way the company is able to create its own niche market across town in India. The USP of the product is a nutritious sandwich at an affordable price. USP is a very important component in developing the product. A strong unique selling proposition makes you stand apart and also plays an important role in branding your product. But, USP alone can guarantee to a product’s success. Superior product quality and at par service, both before and after-sale are very important in creating the foundations of a market for a product. Always remember, with a distinct USP, the company doesn’t even have to bother about competition because if you have developed something which has not been developed by others, then you are the only player or a market leader in that specific product category (Example – iPpod by Apple).
Cost per mille, often abbreviated to CPM, means that advertisers pay for every thousand displays of their message to potential customers (mille is the Latin word for thousand). In the online context, ad displays are usually called "impressions." Definitions of an "impression" vary among publishers, and some impressions may not be charged because they don't represent a new exposure to an actual customer. Advertisers can use technologies such as web bugs to verify if an impression is actually delivered.:59
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer", the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
