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.
A common method of assessing a firm's macro-environment is via a PESTLE (Political, Economic, Social, Technological, Legal, Ecological) analysis. Within a PESTLE analysis, a firm would analyze national political issues, culture and climate, key macroeconomic conditions, health and indicators (such as economic growth, inflation, unemployment, etc.), social trends/attitudes, and the nature of technology's impact on its society and the business processes within the society. 
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, 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.
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".
Advertising: The information you gather in your research will help you define your marketing strategy and create an advertising campaign. Campaigns can include different forms of media, events, direct advertising, paid partnerships, public relations, and more. Before beginning an advertising campaign, set concrete benchmarks that you can use to measure how effective that advertising campaign is.
It's critical that your marketing department uses their understanding and analysis of your business's consumers to offer suggestions for how and where to sell your product. Perhaps they believe an ecommerce site works better than a retail location, or vice versa. Or, maybe they can offer insights into which locations would be most viable to sell your product, either nationally and internationally. How To Start A Digital Marketing Agency With NO MONEY!
