After demonstrating that you understand your prospect's pain points and that you have satisfied customers, at the final stage of your content marketing strategy you can finally introduce your product. What is it that you offer? What solutions could be achieved? Where is the differentiating factor between your product and the competition? How does your model differ from the others and how can your product impact the bottom line?
At this stage of the content marketing process you have to demonstrate why you are the best. Why it is that your solution should be chosen and why your prospects will be happy.
