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". 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".
Vertical integration is when business is expanded through the vertical production line on one business. An example of a vertically integrated business could be Apple. Apple owns all their own software, hardware, designs and operating systems instead of relying on other businesses to supply these. By having a highly vertically integrated business this creates different economies therefore creating a positive performance for the business. Vertical integration is seen as a business controlling the inputs of supplies and outputs of products as well as the distribution of the final product. Some benefits of using a Vertical integration strategy is that costs may be reduced because of the reducing transaction costs which include finding, selling, monitoring, contracting and negotiating with other firms. Also by decreasing outside businesses input it will increase the efficient use of inputs into the business. Another benefit of vertical integration is that it improves the exchange of information through the different stages of the production line. Some competitive advantages could include; avoiding foreclosures, improving the business marketing intelligence, and opens up opportunities to create different products for the market. Some disadvantages of using a Vertical Integration Strategy include the internal costs for the business and the need for overhead costs. Also if the business is not well organised and fully equipped and prepared the business will struggle using this strategy. There are also competitive disadvantages as well, which include; creates barriers for the business, and loses access to information from suppliers and distributors.

Search engine marketing - Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate Search engine optimization, which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings.
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 advertising took place on Instagram and Google. Instagram generally isn't an advertising channel, but when used for branding, you can develop a base of followers that's primed for a gentle product announcement every now and again. Google was definitely used for advertising in this example; the company paid for space on Google -- a program known as pay-per-click (PPC) -- on which to drive traffic to a specific page focused on its product. A classic online ad.
Where your marketing campaigns live depends entirely on where your customers spend their time. It's up to you to conduct market research that determines which types of marketing -- and which mix of tools within each type -- is best for building your brand. Here are several types of marketing that are relevant today, some of which have stood the test of time:
Marketing as a discipline involves all the actions a company undertakes to draw in customers and maintain relationships with them. Networking with potential or past clients is part of the work too, and may include writing thank you emails, playing golf with prospective clients, returning calls and emails quickly, and meeting with clients for coffee or a meal.
Marketing is not confined to any particular type of economy, because goods must be exchanged and therefore marketed in all economies and societies except perhaps in the most primitive. Furthermore, marketing is not a function that is limited to profit-oriented business; even such institutions as hospitals, schools, and museums engage in some forms of marketing. Within the broad scope of marketing, merchandising is concerned more specifically with promoting the sale of goods and services to consumers (i.e., retailing) and hence is more characteristic of free-market economies.
This refers to how the product gets to the customer; the distribution channels and intermediaries such as wholesalers and retailers who enable customers to access products or services in a convenient manner. This third P has also sometimes been called Place or Placement, referring to the channel by which a product or service is sold (e.g. online vs. retail), which geographic region or industry, to which segment (young adults, families, business people), etc. also referring to how the environment in which the product is sold in can affect sales. 
A sales orientation focuses on the selling/promotion of the firm's existing products, rather than developing new products to satisfy unmet needs or wants. This orientation seeks to attain the highest possible sales through promotion and direct sales techniques. The sales orientation "is typically practiced with unsought goods." One study found that industrial companies are more likely to hold a sales orientation than consumer goods companies. The approach may also suit scenarios in which a firm holds dead stock, or otherwise sells a product that is in high demand, with little likelihood of changes in consumer tastes diminishing demand.
Market challenger: The market challenger holds the second highest market share in the category, following closely behind the dominant player. Their market posture is generally offensive because they have less to lose and more to gain by taking risks. They will compete head to head with the market leader in an effort to grow market share. Their overall strategy is to gain market share through product, packaging and service innovations; new market development and redefinition of the to broaden its scope and their position within it.

Selling: Determine where and how you plan to sell to customers. Consumer product companies, for example, sell to wholesalers who then sell to retailers. In the industrial market, the buying process is longer and involves more decision-makers. You may sell locally, nationally, or even internationally, and some companies only sell their products or services online. Your distribution and sales channels impact who buys your products, when they buy them, and how they buy them.

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.
