Armed with extensive online information, a modern buyer requires different skills from a salesperson and frequently exhibits different behavior than buyers of the past. A modern buyer may get very excited about a purchase and spend a lot of time in the research phase and then abruptly stop, ending the sales process sometimes without any reason at all. Often, modern buyers want to reduce the friction of buying and using a product to make it easy for them to achieve the value.
In marketing automation, Ryan Deiss, co-founder of Digital Marketer, often describes the sales funnel as a multi-step, multi-modality process that moves prospective browsers into buyers. It's multi-stepped because lots must occur between the time that a prospect is aware enough to enter your funnel, to the time when they take action and successfully complete a purchase.
