Digital marketing became more sophisticated in the 2000s and the 2010s, when[18][19] the proliferation of devices' capable of accessing digital media led to sudden growth.[20] Statistics produced in 2012 and 2013 showed that digital marketing was still growing.[21][22] With the development of social media in the 2000s, such as LinkedIn, Facebook, YouTube and Twitter, consumers became highly dependent on digital electronics in daily lives. Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.[23]
Marketing is defined by the American Marketing Association as "the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large".[11] The term developed from the original meaning which referred literally to going to market with goods for sale. From a sales process engineering perspective, marketing is "a set of processes that are interconnected and interdependent with other functions of a business aimed at achieving customer interest and satisfaction".[12] How to Start a Social Media Marketing Agency (SMMA) 2020 - Digital Marketing Tutorial for Beginners

It is essential that the internal analysis provide a frank and open evaluation of the firm's superiority in terms of skills, resources or market position since this will provide the basis for competing over the forthcoming planning period. For this reason, some companies engage external consultants, often advertising or marketing agencies, to provide an independent assessment of the firms capabilities and resources.
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.
Market segmentation consists of taking the total heterogeneous market for a product and dividing it into several sub-markets or segments, each of which tends to be homogeneous in all significant aspects.[10] The process is conducted for two main purposes: better allocation of a firm's finite resources and to better serve the more diversified tastes of contemporary consumers. A firm only possesses a certain amount of resources. Thus, it must make choices (and appreciate the related costs) in servicing specific groups of consumers. Moreover, with more diversity in the tastes of modern consumers, firms are noting the benefit of servicing a multiplicity of new markets.
The new digital era has enabled brands to selectively target their customers that may potentially be interested in their brand or based on previous browsing interests. Businesses can now use social media to select the age range, location, gender and interests of whom they would like their targeted post to be seen by. Furthermore, based on a customer's recent search history they can be ‘followed’ on the internet so they see advertisements from similar brands, products and services,[48] This allows businesses to target the specific customers that they know and feel will most benefit from their product or service, something that had limited capabilities up until the digital era.
The marketing discipline had its origins in the early 20th century as an offspring of economics. Economic science had neglected the role of middlemen and the role of functions other than price in the determination of demand levels and characteristics. Early marketing economists examined agricultural and industrial markets and described them in greater detail than the classical economists. This examination resulted in the development of three approaches to the analysis of marketing activity: the commodity, the institution, and the function.
Market leader: The market leader dominates the market by objective measure of market share. Their overall posture is defensive because they have more to lose. Their objectives are to reinforce their prominent position through the use of PR to develop corporate image and to block competitors brand for brand, matching distribution through tactics such as the use of “fighting” brands, pre-emptive strikes, use of regulation to block competitors and even to spread rumours about competitors. Market leaders may adopt unconventional or unexpected approaches to building growth and their tactical responses are likely to include: product proliferation; diversification; multi-branding; erecting barriers to entry; vertical and horizontal integration and corporate acquisitions.
