The bottom of the marketing funnel (BOFU) is where people solidify their decision to purchase from you. Whether your customer has gone through the funnel in one day, one week, or one month, they have to go through all the stages to some degree in order to purchase, even if they go through them quickly. They have to discover your business in TOFU, learn more about it in MOFU, and decide that you’re the place to shop in BOFU.
