(as noted in my earlier https://marketing4optimization.com/2013/11/21/4-new-ps-added-to-internet-marketing-mix/)….
Whatever the number is, just remember to think outside the box of the traditional 4P’s Product, Price, Place, Promotion which are the principles guiding Traditional Marketing and Sales.
SmartDraw has a neat visual of the 4P’s Marketing Mix
I suggested adding 4 additional P’s for Internet Marketing Communications
POSITIONING “Be Different…..Innovate”
PEOPLE “Connect with your Audience and Internal Organization”
PARTICIPATE “Join the Conversation and…. Adapt to Change”
PROCESS “Measure…………Improve…to Manage Complexity”
And SmartDraw has a neat visual of the 7P’s Marketing Mix focused on the Internal Factors to consider when implementing the Marketing Mix : Physical Environment, Process and People.
