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. 
Thanks Matt, yes that’s right. Regarding leads it’s both really! I certainly want to generate more of the right niche/ quality prospects. In short there are 2 distinctly areas; general enquiries which I have a good process for ( but could be improved) the biggest challenge is taking colder leads through the funnel. The sales process can sometimes be quite long, so whilst a well placed offer can work to get someone over line. It’s not very strong for those who are researching etc, hence I need advice about funnel building for regular front of mind contact plus education and industry authority. Does that make sense? Thanks Pete

Trulia did something very similar to Bills.com with their landing page. It starts with a simple form asking for "an address" (which sounds less creepy than "your address," although that's what they mean). Below this simple form field is a bright orange button that contrasts well with the hero image behind the form, and emphasizes that the estimate will be personalized to your home.

A/B testing, or A/B split testing, is a method for testing two versions of a webpage: version "A" and version "B". The goal is to test multiple versions of webpages (e.g., home page vs. product page) or one specific element that changes between variation A and variation B (such as having a lead form on the left hand side or having it placed on the right hand side), FAQ to determine which version is most appealing/effective. This testing method may also be known as A/B/n split testing; the n denoting more than 2 tests being measured and compared. The data for A/B testing is usually measured via click-through rate or an alternative conversion tracking method.[11]
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.
