Product differentiation is a marketing strategy that strives to distinguish a company's products or services from the competition. Successful product differentiation involves identifying and communicating the unique qualities of a company's offerings while highlighting the distinct differences between those offerings and others on the market. Product differentiation goes hand-in-hand with developing a strong value proposition to make a product or service attractive to a target market or audience.
Advertising is a marketing strategy focused on improving the public's attention towards a product. The promotional strategy is useful in increasing a firm's sales and profitability. In some cases, companies must differentiate one product in their line from another to attract new customers or repeat business. This requires effective use of advertising that explains why customers who weren't previously interested should have interest in the new product, or why existing customers need to update. Advertisement provides the information of the product, that is, how a product is different from its competitor’s product. It highlights the special features of the product like attracting shape, color, and quality of the product. Advertisement is also fostering the image of the product to the consumers.
