Marketing strategies should ideally have longer lifespans than individual marketing plans because they contain value propositions and other key elements of a company’s brand, which generally hold consistent over the long haul. In other words, marketing strategies cover big-picture messaging, while marketing plans delineate the logistical details of specific campaigns.
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. 
Digital marketing planning is a term used in marketing management. It describes the first stage of forming a digital marketing strategy for the wider digital marketing system. The difference between digital and traditional marketing planning is that it uses digitally based communication tools and technology such as Social, Web, Mobile, Scannable Surface. Nevertheless, both are aligned with the vision, the mission of the company and the overarching business strategy.
Whereas the vision and mission provide the framework, the "goals define targets within the mission, which, when achieved, should move the organization toward the performance of that mission." Goals are broad primary outcomes whereas, objectives are measurable steps taken to achieve a goal or strategy. In strategic planning, it is important for managers to translate the overall strategy into goals and objectives. Goals are designed to inspire action and focus attention on specific desired outcomes. Objectives, on the other hand, are used to measure an organisation's performance on specific dimensions, thereby providing the organisation with feedback on how well it is achieving its goals and strategies.
Video advertising - This type of advertising in terms of digital/online means are advertisements that play on online videos e.g. YouTube videos. This type of marketing has seen an increase in popularity over time. Online Video Advertising usually consists of three types: Pre-Roll advertisements which play before the video is watched, Mid-Roll advertisements which play during the video, or Post-Roll advertisements which play after the video is watched. Post-roll advertisements were shown to have better brand recognition in relation to the other types, where-as "ad-context congruity/incongruity plays an important role in reinforcing ad memorability". Due to selective attention from viewers, there is the likelihood that the message may not be received. The main advantage of video advertising is that it disrupts the viewing experience of the video and therefore there is a difficulty in attempting to avoid them. How a consumer interacts with online video advertising can come down to three stages: Pre attention, attention, and behavioural decision. These online advertisements give the brand/business options and choices. These consist of length, position, adjacent video content which all directly affect the effectiveness of the produced advertisement time, therefore manipulating these variables will yield different results. Length of the advertisement has shown to affect memorability where-as longer duration resulted in increased brand recognition. This type of advertising, due to its nature of interruption of the viewer, it is likely that the consumer may feel as if their experience is being interrupted or invaded, creating negative perception of the brand. These advertisements are also available to be shared by the viewers, adding to the attractiveness of this platform. Sharing these videos can be equated to the online version of word by mouth marketing, extending number of people reached. Sharing videos creates six different outcomes: these being "pleasure, affection, inclusion, escape, relaxation, and control". As well, videos that have entertainment value are more likely to be shared, yet pleasure is the strongest motivator to pass videos on. Creating a ‘viral’ trend from mass amount of a brands advertisement can maximize the outcome of an online video advert whether it be positive or a negative outcome.
