For United/Optum, hospital services are not seen as something that adds much breadth to the top of the funnel or that draws people into the funnel—certainly not enough to justify Optum taking on the high fixed costs and poor pricing of inpatient care. Rather, hospitals are an additional interaction within the funnel that can be accomplished through partnerships rather than ownership, according to Wichmann. Those partnerships, he says, “will occur in markets where there is maybe fewer assets for us to accumulate and build from."
This funnel is a starting point to a funnel with landing page, OTO-page and thank you page. You can optimize it to your liking. I use Clickfunnels for all my funnels and I highly recommend it due to their analytics. Without analytics your funnel is useless as you do not know at what point people drop off your funnel meaning you can not fix what you do not know.
There are a number of different tools on the market today to help you track these and other metrics, though for most businesses Google Analytics represents the most comprehensive, easy-to-implement solution. Since it’s free, use the service’s funnel-tracking tools until you determine that you need something more advanced and then move on to another sales analytics program or a complete marketing automation program.
Much of this is steeped in buyer psychology. The best marketers in the world know that there is a psychological process that must occur for prospects to whip out those credit cards and turn into buyers or even hyper-active buyers. One such person whose perfected this process is Russell Brunson, an "underground entrepreneur" who founded a company called ClickFunnels, a sales funnel SaaS business that empowers marketers from around the world to build marketing automation without all the hassle.
