Hi Terence, first off I would like to say that an interesting and thorough review. The fact that you go into so much detail about Funnel hacks, both the pro’s and the con’s really makes me believe in it and you. It sounds like something I will definitely consider as soon as I get my own product to sell (which I am still working on at the minute). And if it works then it’s worth every penny I say.
Nauto, a data platform for self-driving cars, helps make autonomous driving safer for companies who manage fleets of self-driving vehicles. Naturally, its customers would need all kinds of information to sell them on this platform. Nauto has it, packaged into a super-simple ebook whose landing page gives you both a brief contact form and some preview statistics to prove why this resource is so important.
Transacted: A sale has transpired when a contract is signed by both parties. From a salesperson’s perspective, the fulfillment of the contract is the responsibility of other parts of the organization, and the salesperson can now focus on the next opportunity. In the case of early-stage start-ups, however, frequently the person that sells is also involved in fulfilling the contract. A signed contract can be booked as revenue from an accounting perspective.
Webflow, a design tool for web developers, packs a lot of information into just a GIF and three form fields. Having the entire sign-up form on a single line is a nice touch here -- not only does it make the page shorter, but filling out each box from left to right shows users how close they are to clicking the fourth blue button and getting started for free. 

The purpose of the transactional landing page is to persuade a visitor to take action by completing a transaction. This is accomplished by providing a form that needs to be filled out. The visitor information is obtained in order to add the visitor’s email address to a mailing list as a prospect. An email campaign can then be developed based on responses to transactional landing pages. The goal is to capture as much information about the visitor as possible. The ultimate goal is to convert the visitor into a customer.[citation needed]
Closed-ended experimentation. Consumers are exposed to several variations of landing pages, altering elements like headlines, formatting and layout while their behavior is observed in an attempt to remove distractions that will take the lead away from the page, including the primary navigation.[9] At the conclusion of the experiment, an optimal page is selected based on the outcome of the experiment.
The first helps direct attention to the goal of the page -- for you to fill out the form -- in a way that's unobtrusive and feels less like a chore. The second gives this page an SEO boost (search engines will have more content to crawl) and assuages any worry from folks who need to know more about a piece of content before handing over their information, all while not distracting people from the chat window.
I'm not sure how the algorithm works (or if there's one at all), but while I was filling it out, I had some anxiety about not qualifying. Once I found out I did, I was excited to fill out the form, which I'm sure most people who are in debt and using this tool are. By making this offer seem more exclusive before the form appeared on the landing page, I'd bet that Bills.com increased conversions pretty significantly.
