The last step in the sales funnel is to keep your momentum going. Follow up with all the new customers you have acquired and ensure they are happy with their product or service. A great way to accomplish this is to offer a membership-based rewards program. This will allow you to remain in contact with customers, giving you the perfect means for telling them about new deals and services.
Of course, if you're going the paid ad route, you could also use Facebook and Google re-targeting to keep that awareness and interest level high. For example, if you've ever noticed after leaving a particular website, that you begin to see their ad everywhere, there's a particular reason for that. Especially if they've already entered your sales funnel, this is a very powerful way to get them to act.
If you’re running a consulting business, for instance, your clients already realize that they’re having certain problems around your service area – like disorganized spending (if you’re in accounting) or a high cost per lead (if you’re in marketing). On the other hand, if you’re running a software development business, your client could be having problems with absolutely anything right from the hours being consumed to other factors that affect deliveries.
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.
