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.
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. 

Very comprehensive review of funnel hacks. I’m glad to see that you actually have it and honestly review it. The cost is rather high, and I think it may not be the best for beginners. i think they may be overwhelmed with funnels if they are just starting out. However, if they have the cash and time to invest, I’m sure that it would benefit them greatly.
Like many of the other landing pages in this post, Shopify's trial landing page keeps it simple. The user-oriented headline is just a few words, for example, and the page relies on simple bullets, not paragraphs, to communicate the trial's details and benefits. There are only a few fields you need to fill out before you get started. All of this makes it easier for you to get to the point: selling online with their tool.
I definitely have subscribed to Funnel hacks and have made my ROI multiple times over already with my affiliate and other business i’m involved in already. Also to back up Russell’s products (Perfect Webinar), I can 100% say that the products are very revolutionary and life changing, including his 2 books if you want to get it: Dotcom Secrets (…) and Expert Secrets (…). His process of doing things is very different but simple at the same time, so if you’re serious in wanting to make money, at least get his books first! Funnel hacks only if you have the money to go for it because the value in there is really amazing.
