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.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer. 
Testing can be conducted sequentially or in parallel. In sequential testing, often the easiest to implement, the various versions of the webpages are made available online for a specified time period. In parallel (split) testing, both versions are made available, and the traffic is divided between the two. The results of sequential split testing can be skewed by differing time periods and traffic patterns in which the different tests are run.
FACT: This amendment ensures essential health benefits are the federal law of the land and maintains other important protections. States have the option to obtain a waiver regarding federal essential health benefits, but the state must publicly attest its purpose for doing so (to reduce the cost of health care coverage, increase the number of people with health care coverage, etc.) and it must specify the benefits it will require instead of the federal standard. NO STATE, under ANY circumstances, may ever obtain a waiver for pre-existing condition protection, prohibition on gender discrimination, for guaranteed issue and renewability, or for the right of dependents to stay on a family plan up to age 26.  
Of course, implementing this isn't easy. You need to first develop your stories, then decide on how you're going to convey those stories and at what drip-rate. For example, your first email or two might go out on the day they first signup, then one email per day might go out afterwards. How much of that will be story-based and how much will be pitches?
