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
In the past, marketing practice tended to be seen as a creative industry, which included advertising, distribution and selling. However, because the academic study of marketing makes extensive use of social sciences, psychology, sociology, mathematics, economics, anthropology and neuroscience, the profession is now widely recognized as a science,[16] allowing numerous universities to offer Master-of-Science (MSc) programs.[17]

The role of a social media manager is easy to infer from the title, but which social networks they manage for the company depends on the industry. Above all, social media managers establish a posting schedule for the company's written and visual content. This employee might also work with the content marketing specialist to develop a strategy for which content to post on which social network.

Affiliate marketing is one of the oldest forms of marketing, and the Internet has brought new life to this old standby. With affiliate marketing, influencers promote other people’s products and get a commission every time a sale is made or a lead is introduced. Many well-known companies like Amazon have affiliate programs that pay out millions of dollars per month to websites that sell their products.
Gap analysis is a type of higher order analysis that seeks to identify the difference between the organisation's current strategy and its desired strategy. This difference is sometimes known as the strategic gap. Mintzberg identifies two types of strategy namely deliberate strategy and inadvertent strategy. The deliberate strategy represents the firm's strategic intent or its desired path while the inadvertent strategy represents the path that the firm may have followed as it adjusted to environmental, competitive and market changes.[51] Other scholars use the terms realized strategy versus intended strategy to refer to the same concepts.[52] This type of analysis indicates whether an organisation has strayed from its desired path during the planning period. The presence of a large gap may indicate the organisation has become stuck in the middle; a recipe for strategic mediocrity and potential failure.
