As you can probably imagine, this sort of thing is particularly frustrating if you’re selling an expensive product or service, but you can even see it happen with something as simple as deciding where to go for lunch. For example, if you’re hungry and in a hurry, you might pick the closest restaurant. But, if a friend asks where you’re going and says, “Oh, that’s where I got food poisoning last week”, there’s a good chance you’ll end up going somewhere else.
Unfortunately, the reason why we call it a marketing funnel instead of a marketing journey or marketing waterfall is that not everyone who enters your funnel will end up buying. At each stage in the buying process, you lose some potential customers, but a good marketing funnel will keep those losses to a minimum and produce the maximum number of sales from your marketing.
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.
