Of course, regardless of how they enter into your funnel, your goal as a marketer is to move them through the multiple stages that will take them from prospect to buyer. And once they're aware of you, you need to build their interest. To do this, you need to establish a relationship with the customer. You might have enticed them with a great offer (lead magnet) to grab their email address, but actually moving them through the funnel is a far greater challenge.
There are email warming sequences that include things like personalized value-driven stories, tutorials and even soft pushes to webinars, and of course product suggestions that happen over days or even weeks. The truth is that most prospects won't buy from your website at first glance, especially if they're only just becoming aware of you today. It takes time. Thus, the funnel is a multi-modality process, as there are a variety of relationship-building experiences and "touches" that occur through several stages.
However, what Brunson cleverly conceived with ClickFunnels is to create a SaaS that can integrate with the world's most popular platforms and virtually anyone can quietly launch a funnel in hours as opposed to weeks of hefty coding and programming. As a fervent user of ClickFunnels myself, I can tell you that the system is impressive beyond measure.
