Some blog owners are use split testing to understand the behaviors of their blog visitors, as well as their priorities. The best way to do the split testing is to include minor and major elements of the whole blog page, so one would know specific problems on the site. Basically, split testing works when a blog owner sets up two different headlines on the home page, two different copies, etc.
There would be a group of people and they would be divided into two groups, A and B. Moreover, the test would also be categorized as A and B. The Test A would be sent to the A group and Test B to the B group. After some time, the blogger would then figure out which among the test works best and yielded the results needed by the blog. Once the blog features are tested using this method, a blog owner would know if the feature is great for the blog or not.
