Ok. This is a map. Like the marketing maps we have talked about before, this is yet another one of the many, many tools to help understand the customer’s journey to conversion, as well as what is working and what isn’t. A marketing tunnel also tells you at what step of the journey do you lose your customer leads? What engaging marketing technique is attracting conversions? All of these questions are things you ask when creating a marketing funnel, and later get answered throughout your campaign.
