Marketing’s principal function is to promote and facilitate exchange. Through marketing, individuals and groups obtain what they need and want by exchanging products and services with other parties. Such a process can occur only when there are at least two parties, each of whom has something to offer. In addition, exchange cannot occur unless the parties are able to communicate about and to deliver what they offer. Marketing is not a coercive process: all parties must be free to accept or reject what others are offering. So defined, marketing is distinguished from other modes of obtaining desired goods, such as through self-production, begging, theft, or force.
The category/brand development index is a method used to assess the sales potential for a region or market and identify market segments that can be developed (i.e. high CDI and high BDI). In addition, it may be used to identify markets where the category or brand is under-performing and may signal underlying marketing problems such as poor distribution (i.e. high CDI and low BDI).
Commodity analysis studies the ways in which a product or product group is brought to market. A commodity analysis of milk, for example, traces the ways in which milk is collected at individual dairy farms, transported to and processed at local dairy cooperatives, and shipped to grocers and supermarkets for consumer purchase. Institutional analysis describes the types of businesses that play a prevalent role in marketing, such as wholesale or retail institutions. For instance, an institutional analysis of clothing wholesalers examines the ongoing concerns that wholesalers face in order to ensure both the correct supply for their customers and the appropriate inventory and shipping capabilities. Finally, a functional analysis examines the general tasks that marketing performs. For example, any marketing effort must ensure that the product is transported from the supplier to the customer. In some industries this transportation function may be handled by a truck, while in others it may be done by mail or e-mail, facsimile, television signal, the Internet, or airline. All these institutions perform the same function.
This refers to the process of setting a price for a product, including discounts. The price need not be monetary; it can simply be what is exchanged for the product or services, e.g. time, energy, or attention or any sacrifices consumers make in order to acquire a product or service. The price is the cost that a consumer pays for a product—monetary or not. Methods of setting prices are in the domain of pricing science. 
Pixels track everyone who comes to your site, and you can build custom audiences around them. For example, if you post content about how to learn to drive a semi-truck, and you track visitors with pixels, you can then market truck driving certification to people who have already shown an interest in that already because they visited that specific page. And your conversions will skyrocket.
