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.

Barney stated that for resources to hold potential as sources of sustainable competitive advantage, they should be valuable, rare and imperfectly imitable.[75] A key insight arising from the resource-based view is that not all resources are of equal importance nor possess the potential to become a source of sustainable competitive advantage.[73] The sustainability of any competitive advantage depends on the extent to which resources can be imitated or substituted.[6] Barney and others point out that understanding the causal relationship between the sources of advantage and successful strategies can be very difficult in practice.[75] Barney uses the term "causally ambiguous" which he describes as a situation when "the link between the resources controlled by the firm and the firm's sustained competitive advantage is not understood or understood only very imperfectly." Thus, a great deal of managerial effort must be invested in identifying, understanding and classifying core competencies. In addition, management must invest in organisational learning to develop and maintain key resources and competencies.
Social Media Marketing - The term 'Digital Marketing' has a number of marketing facets as it supports different channels used in and among these, comes the Social Media. When we use social media channels ( Facebook, Twitter, Pinterest, Instagram, Google+, etc.) to market a product or service, the strategy is called Social Media Marketing. It is a procedure wherein strategies are made and executed to draw in traffic for a website or to gain attention of buyers over the web using different social media platforms.

Marketing strategies should ideally have longer lifespans than individual marketing plans because they contain value propositions and other key elements of a company’s brand, which generally hold consistent over the long haul. In other words, marketing strategies cover big-picture messaging, while marketing plans delineate the logistical details of specific campaigns.
Marketing research, conducted for the purpose of new product development or product improvement, is often concerned with identifying the consumer's unmet needs.[22] Customer needs are central to market segmentation which is concerned with dividing markets into distinct groups of buyers on the basis of "distinct needs, characteristics, or behaviors who might require separate products or marketing mixes."[23] Needs-based segmentation (also known as benefit segmentation) "places the customers' desires at the forefront of how a company designs and markets products or services."[24] Although needs-based segmentation is difficult to do in practice, it has been proved to be one of the most effective ways to segment a market.[25][22] In addition, a great deal of advertising and promotion is designed to show how a given product's benefits meet the customer's needs, wants or expectations in a unique way.[26]
Affiliate marketing is one of the oldest forms of marketing, and the Internet has brought new life to this old standby. With affiliate marketing, influencers promote other people’s products and get a commission every time a sale is made or a lead is introduced. Many well-known companies like Amazon have affiliate programs that pay out millions of dollars per month to websites that sell their products.

In-game advertising - In-Game advertising is defined as "inclusion of products or brands within a digital game."[60] The game allows brands or products to place ads within their game, either in a subtle manner or in the form of an advertisement banner. There are many factors that exist in whether brands are successful in their advertising of their brand/product, these being: Type of game, technical platform, 3-D and 4-D technology, game genre, congruity of brand and game, prominence of advertising within the game. Individual factors consist of attitudes towards placement advertisements, game involvement, product involvement, flow or entertainment. The attitude towards the advertising also takes into account not only the message shown but also the attitude towards the game. Dependent of how enjoyable the game is will determine how the brand is perceived, meaning if the game isn't very enjoyable the consumer may subconsciously have a negative attitude towards the brand/product being advertised. In terms of Integrated Marketing Communication "integration of advertising in digital games into the general advertising, communication, and marketing strategy of the firm"[60] is an important as it results in a more clarity about the brand/product and creates a larger overall effect.
