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. Digital marketing extends to non-Internet channels that provide digital media, such as television, mobile phones (SMS and MMS), callback, and on-hold mobile ring tones. The extension to non-Internet channels differentiates digital marketing from online marketing.
Barney stated that for resources to hold potential as sources of sustainable competitive advantage, they should be valuable, rare and imperfectly imitable. 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. The sustainability of any competitive advantage depends on the extent to which resources can be imitated or substituted. Barney and others point out that understanding the causal relationship between the sources of advantage and successful strategies can be very difficult in practice. 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.
Digital marketing became more sophisticated in the 2000s and the 2010s, when the proliferation of devices' capable of accessing digital media led to sudden growth. Statistics produced in 2012 and 2013 showed that digital marketing was still growing. With the development of social media in the 2000s, such as LinkedIn, Facebook, YouTube and Twitter, consumers became highly dependent on digital electronics in daily lives. Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.
Positioning concerns how to position a product in the minds of consumers and inform what attributes differentiate it from the competitor's products. A firm often performs this by producing a perceptual map, which denotes similar products produced in the same industry according to how consumers perceive their price and quality. From a product's placing on the map, a firm would tailor its marketing communications to meld with the product's perception among consumers and its position among competitors' offering. 
Strategic analysis is designed to address the first strategic question, "Where are we now?"  Traditional market research is less useful for strategic marketing because the analyst is not seeking insights about customer attitudes and preferences. Instead strategic analysts are seeking insights about the firm's operating environment with a view to identifying possible future scenarios, opportunities and threats.

Email marketing - Email marketing in comparison to other forms of digital marketing is considered cheap; it is also a way to rapidly communicate a message such as their value proposition to existing or potential customers. Yet this channel of communication may be perceived by recipients to be bothersome and irritating especially to new or potential customers, therefore the success of email marketing is reliant on the language and visual appeal applied. In terms of visual appeal, there are indications that using graphics/visuals that are relevant to the message which is attempting to be sent, yet less visual graphics to be applied with initial emails are more effective in-turn creating a relatively personal feel to the email. In terms of language, the style is the main factor in determining how captivating the email is. Using casual tone invokes a warmer and gentle and inviting feel to the email in comparison to a formal style. For combinations; it's suggested that to maximize effectiveness; using no graphics/visual alongside casual language. In contrast using no visual appeal and a formal language style is seen as the least effective method. A DAY IN THE LIFE OF A DIGITAL MARKETING MANAGER | WHAT DOES A DIGITAL MARKETER DO? & SALARIES
