To overcome the deficiencies of the 4P model, some authors have suggested extensions or modifications to the original model. Extensions of the four P's are often included in cases such as services marketing where unique characteristics (i.e. intangibility, perishability, heterogeneity and the inseparability of production and consumption) warrant additional consideration factors. Other extensions have been found necessary for retail marketing, industrial marketing, and internet marketing
Vertical integration is when business is expanded through the vertical production line on one business. An example of a vertically integrated business could be Apple. Apple owns all their own software, hardware, designs and operating systems instead of relying on other businesses to supply these.[88] By having a highly vertically integrated business this creates different economies therefore creating a positive performance for the business.[citation needed] Vertical integration is seen as a business controlling the inputs of supplies and outputs of products as well as the distribution of the final product.[citation needed] Some benefits of using a Vertical integration strategy is that costs may be reduced because of the reducing transaction costs which include finding, selling, monitoring, contracting and negotiating with other firms. Also by decreasing outside businesses input it will increase the efficient use of inputs into the business. Another benefit of vertical integration is that it improves the exchange of information through the different stages of the production line.[citation needed] Some competitive advantages could include; avoiding foreclosures, improving the business marketing intelligence, and opens up opportunities to create different products for the market.[89] Some disadvantages of using a Vertical Integration Strategy include the internal costs for the business and the need for overhead costs. Also if the business is not well organised and fully equipped and prepared the business will struggle using this strategy. There are also competitive disadvantages as well, which include; creates barriers for the business, and loses access to information from suppliers and distributors.[89]

Cross-platform measurement: The number of marketing channels continues to expand, as measurement practices are growing in complexity. A cross-platform view must be used to unify audience measurement and media planning. Market researchers need to understand how the Omni-channel affects consumer's behaviour, although when advertisements are on a consumer's device this does not get measured. Significant aspects to cross-platform measurement involves deduplication and understanding that you have reached an incremental level with another platform, rather than delivering more impressions against people that have previously been reached (Whiteside, 2016).[51] An example is ‘ESPN and comScore partnered on Project Blueprint discovering the sports broadcaster achieved a 21% increase in unduplicated daily reach thanks to digital advertising’ (Whiteside, 2016).[51] Television and radio industries are the electronic media, which competes with digital and other technological advertising. Yet television advertising is not directly competing with online digital advertising due to being able to cross platform with digital technology. Radio also gains power through cross platforms, in online streaming content. Television and radio continue to persuade and affect the audience, across multiple platforms (Fill, Hughes, & De Franceso, 2013).[54]
From a model-building perspective, the 4 Ps has attracted a number of criticisms. Well-designed models should exhibit clearly defined categories that are mutually exclusive, with no overlap. Yet, the 4 Ps model has extensive overlapping problems. Several authors stress the hybrid nature of the fourth P, mentioning the presence of two important dimensions, "communication" (general and informative communications such as public relations and corporate communications) and "promotion" (persuasive communications such as advertising and direct selling). Certain marketing activities, such as personal selling, may be classified as either promotion or as part of the place (i.e., distribution) element.[47] Some pricing tactics, such as promotional pricing, can be classified as price variables or promotional variables and, therefore, also exhibit some overlap. What is Digital Marketing?
Know your products. Spend time articulating the benefits of your products in addition to the features. How will they make a difference in someone's life? Why does that matter to your customers? The most effective marketing speaks to the emotions of consumers, and that connection is created when you can articulate the benefit your business provides.
The third and final stage requires the firm to set a budget and management systems; these must be measurable touchpoints, such as audience reached across all digital platforms. Furthermore, marketers must ensure the budget and management systems are integrating the paid, owned and earned media of the company.[84] The Action and final stage of planning also requires the company to set in place measurable content creation e.g. oral, visual or written online media.[85]
Diversification is the riskiest area for a business. This is where a new product is sold to a new market.[83] There are two type of Diversification; horizontal and vertical. 'Horizontal diversification focuses more on product(s) where the business is knowledgeable, whereas vertical diversification focuses more on the introduction of new product into new markets, where the business could have less knowledge of the new market.[84] FREE Digital Marketing Course
