During decline, demand for a good begins to taper off, and the firm may opt to discontinue the manufacture of the product. This is so, if revenue for the product comes from efficiency savings in production, over actual sales of a good/service. However, if a product services a niche market, or is complementary to another product, it may continue the manufacture of the product, despite a low level of sales/revenue being accrued. 
Market pioneers are known to often open a new market to consumers based off a major innovation. 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. 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. Technological Leadership means gaining an advantage through either Research and Development or the “learning curve”. 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. 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. However, while Market Pioneers may have the “highest probability of engaging in product development” 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”, they incur larger disadvantages cost-wise.
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.

Marketing warfare strategies are competitor-centered strategies drawn from analogies with the field of military science. Warfare strategies were popular in the 1980s, but interest in this approach has waned in the new era of relationship marketing. An increased awareness of the distinctions between business and military cultures also raises questions about the extent to which this type of analogy is useful. In spite of its limitations, the typology of marketing warfare strategies is useful for predicting and understanding competitor responses.
Digital marketing is the component of marketing that utilizes internet and online based digital technologies such as desktop computers, mobile phones and other digital media and platforms to promote products and services. Its development during the 1990s and 2000s, changed the way brands and businesses use technology for marketing. As digital platforms became increasingly incorporated into marketing plans and everyday life, and as people increasingly use digital devices instead of visiting physical shops, digital marketing campaigns have become prevalent, employing combinations of search engine optimization (SEO), search engine marketing (SEM), content marketing, influencer marketing, content automation, campaign marketing, data-driven marketing, e-commerce marketing, social media marketing, social media optimization, e-mail direct marketing, display advertising, e–books, and optical disks and games have become commonplace.

The extension to non-Internet channels differentiates digital marketing from online marketing.

A disadvantage of using a diversification strategy is that the benefits could take a while to start showing, which could lead the business to believe that the strategy in ineffective. Another disadvantage or risk is, it has been shown that using the horizontal diversification method has become harmful for stock value, but using the vertical diversification had the best effects.

Market nicher: The market nicher occupies a small niche in the market in order to avoid head to head competition.

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.
The digital marketer usually focuses on a different key performance indicator (KPI) for each channel so they can properly measure the company's performance across each one. A digital marketer who's in charge of SEO, for example, measures their website's "organic traffic" -- of that traffic coming from website visitors who found a page of the business's website via a Google search. a REALISTIC Day in the Life (Entrepreneur & Digital Marketing Manager)
