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] 

I’ve checked out a few of Russell Brunson’s content, on youtube, and he seems to really know his stuff. To be honest, at first I was skeptical and thought he could be a fraud but then I had a read of his book. It was actually really interesting and full of useful advice, also I seen that he’s speaking at Grant Cardone’s 10X seminar (or something like that), I know he’s legit so Russell – and his program – must be too!
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]
If a sales opportunity does not move down the funnel, the sale will not happen and the opportunity should be removed, hence the “leaky” funnel. A leaky funnel is not necessarily bad; as a salesperson, you want to focus on opportunities that are likely to yield results. It is the nature of sales to have to remove an opportunity from your funnel. It does not mean that you will not sell to that account (a positive action by the customer can put them back into the funnel), but for the time being, you should centre your attention on opportunities that remain in the funnel.
The messaging on the page reinforces the reason for their click, reducing or removing confusion and therefore increasing conversion rates. This improves overall user experience and reduces the bounce rate (individuals leaving the site without converting or navigating to another portion of the site) for the page. Good message matching can increase conversion by up to 50% in many cases.[13]
Landing page optimization (LPO) is one part of a broader Internet marketing process called conversion optimization, or conversion rate optimization (CRO), with the goal of improving the percentage of visitors to the website that become sales leads and customers. A landing page is a webpage that is displayed when a potential customer clicks an advertisement or a search engine result link. This webpage typically displays content that is a relevant extension of the advertisement or link. LPO aims to provide page content and appearance that makes the webpage more appealing to target audiences.

Landing pages originated with the IT departments of Microsoft in late 2003 in response to poor online sales of Office.[5] The process was tedious and time-consuming. As a result, in 2009, several startups, including Unbounce, were formed to simplify and streamline the process. The rise of cloud computing and e-commerce around 2009 provided ideal conditions for these startups to flourish.[5] Since then the customer requirements changed, requesting integrations with other solutions such as email marketing, lead nurturing and customer relationship management systems.
