You need to understand your audience like you do your very own yourself. You are aware of your dislikes and likes, you know what problems you face and you know the sort of people you will let help with those problems. If you learn to know your audience in the same manner, the chances of you establishing a genuine connection increase vastly. You will also be able to guide more people through your sales funnel and get those coveted ‘closed-wons’.
If you're wondering what a sales funnel is, simply imagine a real-world funnel. At the top of that funnel, some substance is poured in, which filters down towards one finite destination. In sales, something similar occurs. At the top, lots of visitors arrive who may enter your funnel. However, unlike the real-world funnel, not all who enter the sales funnel will reemerge out from the other end.
