Typically, online marketers have utilized standard “Split tests” to try and improve marketing and merchandising approaches. A split test allows a marketer to split traffic across different versions of a web page in an effort to identify topper-forming marketing variables.
During these testing scenarios marketers try to identify promotions that significantly outperform others, while testing titles and headers for the highest level of customer engagement.
Unfortunately these testing method doesn’t consider where are the people going from.
Customers from different sources could have different purposes and behavior. So it would be better to send web-surfers from Google, Yahoo, MSN to one test pages and marketes from WarriorForum, “How To Corp” forum to another test pages.
