Steps in Sales Funnel – This lays out for you, point-by-point, each page and step the customer goes through on their way to making a purchase. In some cases, it also works to point out some of the follow-up steps and “if-then” scenarios. For instance, how does the funnel respond “intelligently” to get prospects who didn’t buy to come back to the website?
Much of this is steeped in buyer psychology. The best marketers in the world know that there is a psychological process that must occur for prospects to whip out those credit cards and turn into buyers or even hyper-active buyers. One such person whose perfected this process is Russell Brunson, an "underground entrepreneur" who founded a company called ClickFunnels, a sales funnel SaaS business that empowers marketers from around the world to build marketing automation without all the hassle.
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.
