To make an effective plan, there is a famous rule called 4P's. Here, P's stand for Price, Product, Promotion and Placement. In this another P is added called People. Today while doing digital marketing or the traditional marketing one should understand people or the customers you are dealing with. It's important to figure out what is significant for the business, and later make a plan accordingly.
Plan of actions: consists in a very detailed description of the procedures and means to implement the actions we want to take. For example, if the strategy implies a raise in advertising volume, the plan of actions should establish where the advertisements will be placed, the dates and frequency of the advertising campaigns, a set of procedures to evaluate their effectiveness. The actions we plan to take must be clearly formulated, measurable, and the results must be monitored and evaluated.
