Split testing simply gives you the ability to find out which page is performing best with a specific traffic source

First, create a link

Then, you place another url you'd like to test against the original one

example vip 1 versus vip 5

then you select how much traffic you want going to it, i.e 50%

and the tracker will split the visitors between the 2 pages, and then will let you know in the stats how each one is performing.

based on that you can turn off the split test and continue running traffic to the best performing page with that traffic source / vendor

If you are NOT using funnel x roi, make sure you install the tracking pixels FIRST before running any traffic so the system can track the actions / sales and subscribers.
