One quick word of caution, though. With every piece of content you create for every stage of your funnel, you’re generating data. Though all of it is useful to your sales process in some way, it’s easy to get bogged down in data and metrics tracking instead of focusing on the few key performance indicators (KPIs) that will actually give you the information needed to make meaningful improvements.
If you're wondering what a sales funnel is, simply imagine a real-world funnel. At the top of that funnel, some substance is poured in, which filters down towards one finite destination. In sales, something similar occurs. At the top, lots of visitors arrive who may enter your funnel. However, unlike the real-world funnel, not all who enter the sales funnel will reemerge out from the other end.
