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).

The Chartered Institute of Marketing defines marketing as "the management process responsible for identifying, anticipating and satisfying customer requirements profitably".[14] A similar concept is the value-based marketing which states the role of marketing to contribute to increasing shareholder value.[15] In this context, marketing can be defined as "the management process that seeks to maximise returns to shareholders by developing relationships with valued customers and creating a competitive advantage".[15]
With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
Marketing strategy and marketing mix are related elements of a comprehensive marketing plan. While marketing strategy is aligned with setting the direction of a company or product/service line, the marketing mix is majorly tactical in nature and is employed to carry out the overall marketing strategy. The 4P's of the marketing mix (Price, Product, Place and Promotion) represent the tools that marketers can leverage while defining their marketing strategy to create a marketing plan.[110]
For example, to implement PPC using Google AdWords, you'll bid against other companies in your industry to appear at the top of Google's search results for keywords associated with your business. Depending on the competitiveness of the keyword, this can be reasonably affordable, or extremely expensive, which is why it's a good idea to focus building your organic reach, too.
Market pioneers are known to often open a new market to consumers based off a major innovation.[93] They emphasise these product developments, and in a significant number of cases, studies have shown that early entrants – or pioneers – into a market have serious market-share advantages above all those who enter later.[94] Pioneers have the first-mover advantage, and in order to have this advantage, business’ must ensure they have at least one or more of three primary sources: Technological Leadership, Preemption of Assets or Buyer Switching Costs.[92] Technological Leadership means gaining an advantage through either Research and Development or the “learning curve”.[92] This lets a business use the research and development stage as a key point of selling due to primary research of a new or developed product. Preemption of Assets can help gain an advantage through acquiring scarce assets within a certain market, allowing the first-mover to be able to have control of existing assets rather than those that are created through new technology.[92] Thus allowing pre-existing information to be used and a lower risk when first entering a new market. By being a first entrant, it is easy to avoid higher switching costs compared to later entrants. For example, those who enter later would have to invest more expenditure in order to encourage customers away from early entrants.[92] However, while Market Pioneers may have the “highest probability of engaging in product development”[95] and lower switching costs, to have the first-mover advantage, it can be more expensive due to product innovation being more costly than product imitation. It has been found that while Pioneers in both consumer goods and industrial markets have gained “significant sales advantages”,[96] they incur larger disadvantages cost-wise.
Unlike most offline marketing efforts, digital marketing allows marketers to see accurate results in real time. If you've ever put an advert in a newspaper, you'll know how difficult it is to estimate how many people actually flipped to that page and paid attention to your ad. There's no surefire way to know if that ad was responsible for any sales at all.
Taking these statistics into consideration, online marketing is a critical element of a complete marketing strategy. It is vital for marketers to use online tools such as social media and digital advertising, both on website and mobile device applications, and internet forums. Considering an appropriate distribution channel for products purchased online is also an important step. The psychology of digital marketing. Rory Sutherland, Ogilvy

Research and testing: Before you can take your idea public, you should perform marketing research and testing. Marketing departments usually test new product concepts with focus groups and surveys to gauge consumer interest, refine product ideas, and determine what price to set. Researching your competitors can help you set an optimal price and generate ideas for positioning your brand in an existing market. What Is Digital Marketing? And How Does It Work?
