A 2011 meta analyses found that the factors with the greatest impact on sales performance are a salesperson's sales related knowledge (knowledge of market segments, sales presentation skills, conflict resolution, and products), degree of adaptiveness (changing behavior based on the aforementioned knowledge), role clarity (salesperson's role is expressly to sell), cognitive aptitude (intelligence) and work engagement (motivation and interest in a sales role).
Marketing research is a systematic process of analyzing data that involves conducting research to support marketing activities and the statistical interpretation of data into information. This information is then used by managers to plan marketing activities, gauge the nature of a firm's marketing environment and to attain information from suppliers. A distinction should be made between marketing research and market research. Market research involves gathering information about a particular target market. As an example, a firm may conduct research in a target market, after selecting a suitable market segment. In contrast, marketing research relates to all research conducted within marketing. Market research is a subset of marketing research.
Strategic planning focuses on the 3C's, namely: Customer, Corporation and Competitors. A detailed analysis of each factor is key to the success of strategy formulation. The 'competitors' element refers to an analysis of the strengths of the business relative to close rivals, and a consideration of competitive threats that might impinge on the business' ability to move in certain directions. The 'customer' element refers to an analysis of any possible changes in customer preferences that potentially give rise to new business opportunities. The 'corporation' element refers to a detailed analysis of the company's internal capabilities and its readiness to leverage market-based opportunities or its vulnerability to external threats.

Personal selling involves an oral presentation given by a salesperson who approaches an individual or a group of potential customers. Personal selling allows for two-way communication and relationship building that can aid both the buyer and the seller in their goals. Personal selling is most commonly seen in business-to-business marketing (e.g.: selling machinery to a factory, selling paper to a print shop), but it can also be found in business-to-consumer marketing (e.g.: selling cars at a dealership). 
Marketing strategy involves mapping out the company's direction for the forthcoming planning period, whether that be three, five or ten years. It involves undertaking a 360° review of the firm and its operating environment with a view to identifying new business opportunities that the firm could potentially leverage for competitive advantage. Strategic planning may also reveal market threats that the firm may need to consider for long-term sustainability. Strategic planning makes no assumptions about the firm continuing to offer the same products to the same customers into the future. Instead, it is concerned with identifying the business opportunities that are likely to be successful and evaluates the firm's capacity to leverage such opportunities. It seeks to identify the strategic gap; that is the difference between where a firm is currently situated (the strategic reality or inadvertent strategy) and where it should be situated for sustainable, long-term growth (the strategic intent or deliberate strategy).
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.
