Trulia did something very similar to 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.

I am currently using LeadPages and was thinking of moving to Clickfunnels after my 14 day trial (depending on how it goes). It gets a bit annoying doing the integrations sometimes, especially that you have to always remember to connect the flow for things to work. That’s why so far I really appreciate the all-in-one feature that ClickFunnels have. I am also planning to sell my own products in the nearest future and really appreciate you letting us know about how to save $$$ by using ‘Funnel Hacks’
Pros: Everything is included. Everything you need from an online marketing/funnels standpoint is all included. No piecing together pieces of software or programs here and there. Integrations are so easy and everything just works. Documentation is superb if you have any questions. You need to implement funnels from a strategy standpoint and every alternative is just much more complicated.
Cons: Despite the promised functionality, Backpack and Actionetics are highly limited. In 2-3 years, the functionality may be unparalleled, but at the moment the little bugs make it an extremely frustrating process. I can't find a good reason to pay the additional money when there are alternatives like Mailchimp for a far better CRM and other decent affiliate solutions out there.
Before I go much further, it's important to note that we are comparing two similar solutions, but by no means are they exact matches. However, there are plenty of overlaps that can confuse a good buying  decision. That’s why I’ve spent so much time and effort on this Clickfunnels Review. I want my readers and audience to get an exhaustive look on the sales funnel tools of choice and how they can best benefit.
Just found your post in my study of sales funnels. You bring the heart to it. This is really the missing link to online success. Thank you for explaining it so easily. Am not compelled to download the free traffic course because I can imagine the quality of info it would have not to mention returning to the site to have my buffer on other interesting content. Thanks.
OK, ok…that said, it may take you awhile to get acquainted and comfortable with all the Clickfunnels features — there are a lot of details you’ll have to figure out once your sales funnel is built. Things like what domain you’re going to assign it to (you can buy one for an easy $20 through Clickfunnels or attach it to an existing domain), your SEO data, if you’re going to integrate it with your email platform, creating split test pages, testing your live funnel, etc, etc.

Pros: Funnels involve many moving parts, pages, and pieces. Having designed these for years myself, I expected Clickfunnels to be another newbie tool, but it's so so much more. You can easily set up funnels for specific markets, tying them together and tracking in a way that's visual (not Kanban, but close) and easy to understand. Instead of complex interfaces, you have an easy step by step way to get things going quickly. As an experienced user, I was impressed by the value this delivers for people regardless of skill set. There's so many smart elements - for example, preview your page and it shows you the version regardless of cache, so you're not stuck emptying your browser. Few years ago this would have cost you thousands to set up individually, and left you needing tech assistance. Clickfunnels eliminates that and makes it so even a beginner can use this tool.

For example, if you’re selling an eBook, you could offer a free chapter in exchange for their email address. Submitting their email is a low barrier to entry, and they’ll receive a lot of value in return. From there, you can use their email to push them deeper into the sales funnel, especially since they have already shown interest in your product.  
Prospecting and marketing are all the things you do to get people into the first of your sales funnel stages. Note that stages are broken into two or more steps wherever possible. A demo could be called a single stage, but in real life it involves a lot of things: contacting the customer, sending reminders, doing the demo, and then following up. Whatever your own sales stages look like, the support you need in managing them will be the same.
