In a recent conversation I had with Perry Belcher, co-founder of Native Commerce Media, he told me that you also need to train your prospects to click on links. For example, you could have them click on a link of what interests them or link them to a blog post or eventually to a product or service that you're selling, but you need to train them to build a habit of clicking on those links from the very beginning.
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.
