PPC advertising enables marketers to reach Internet users on a number of digital platforms through paid ads. Marketers can set up PPC campaigns on Google, Bing, LinkedIn, Twitter, Pinterest, or Facebook and show their ads to people searching for terms related to the products or services. PPC campaigns can segment users based on their demographic characteristics (such as by age or gender), or even target their particular interests or location. The most popular PPC platforms are Google Ads and Facebook Ads.
In the parlance of digital marketing, advertisers are commonly referred to as sources, while members of the targeted ads are commonly called receivers. Sources frequently target highly specific, well-defined receivers. For example, after extending the late-night hours of many of its locations, McDonald's needed to get the word out. It targeted shift workers and travelers with digital ads because the company knew that these people made up a large segment of its late-night business. McDonald's encouraged them to download a new Restaurant Finder app, targeting them with ads placed at ATMs and gas stations, as well as on websites that it knew its customers frequented at night.
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). 
As the speed of change in the marketing environment quickens, time horizons are becoming shorter. Nevertheless, most firms carry out strategic planning every 3– 5 years and treat the process as a means of checking whether the company is on track to achieve its vision and mission. Ideally, strategies are both dynamic and interactive, partially planned and partially unplanned. Strategies are broad in their scope in order to enable a firm to react to unforeseen developments while trying to keep focused on a specific pathway. A key aspect of marketing strategy is to keep marketing consistent with a company's overarching mission statement.
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.
