For example, to implement PPC using Google AdWords, you'll bid against other companies in your industry to appear at the top of Google's search results for keywords associated with your business. Depending on the competitiveness of the keyword, this can be reasonably affordable, or extremely expensive, which is why it's a good idea to focus building your organic reach, too.
Digital marketing poses special challenges for its purveyors. Digital channels are proliferating rapidly, and digital marketers have to keep up with how these channels work, how they're used by receivers, and how to use these channels to effectively market their products or services. In addition, it's becoming more difficult to capture receivers' attention, because receivers are increasingly inundated with competing ads. Digital marketers also find it challenging to analyze the vast troves of data they capture and then exploit this information in new marketing efforts.
After setting the goals marketing strategy or marketing plan should be developed. The marketing strategy plan provides an outline of the specific actions to be taken over time to achieve the objectives. Plans can be extended to cover many years, with sub-plans for each year. Plans usually involve monitoring, to assess progress, and prepare for contingencies if problems arise. Simultaneous such as customer lifetime value models can be used to help marketers conduct "what-if" analyses to forecast what potential scenarios arising from possible actions, and to gauge how specific actions might affect such variables as the revenue-per-customer and the churn rate.
The marketing discipline had its origins in the early 20th century as an offspring of economics. Economic science had neglected the role of middlemen and the role of functions other than price in the determination of demand levels and characteristics. Early marketing economists examined agricultural and industrial markets and described them in greater detail than the classical economists. This examination resulted in the development of three approaches to the analysis of marketing activity: the commodity, the institution, and the function.
Proper branding is critical to your long term success. A lot of people think of branding as logo development. But in reality, branding is managing the thoughts and feelings of your customers to ensure that you are what they desire. If your desired brand image isn’t what’s in the minds of your target audience, you’ve got to figure out where the gaps are and how to address them. And fixing those issues is hard work because the old adage still rings true – the customer is always right. What Is Digital Marketing? | Digital Marketing Tutorial For Beginners | Edureka
4. How do all the other elements work? Ideally all the elements that visually represent your brand should feel like they are from the same family.

With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
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. 
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.
