The Top of the Funnel

When thinking about ers per say, or creating customers per say, we like to break the funnel into three parts. We are talking about top of funnel, mendal funnel, bottom of funnel. The idea is that as people move along, different metric matter. For example, I want to track news letter optins. Is that list growing? For example, that might be wone. It's the maybe time, average time that we're tracking. That is what we're really trying to understand in analytics.
