The next part is about getting your audience to willingly give you their contact details by submitting a form or something equivalent to that. Why is this important? Because, when they voluntarily allow you to contact them, it indicates that they are interested in you. And, secondly, you would be able to further nurture them and push them into the next stage.
So where do we go from here?  The funnel and Customer Decision Journey aren’t going away.  They are useful models, and will continue to be helpful in certain contexts.  But marketing today requires a new mental map to navigate a changing landscape. We need a model that informs marketers how to enable and empower, not just persuade and promote.  There are a variety of alternatives including journey, orbit, relationship, and experience.
The marketing funnel is a visualization for understanding the process of turning leads into customers, as understood from a marketing (and sales) perspective. The idea is that, like a funnel, marketers cast a broad net to capture as many leads as possible, and then slowly nurture prospective customers through the purchasing decision, narrowing down these candidates in each stage of the funnel.
