In this guide, they cover the basics of split-testing and how a lot, if not all, of the tedious tasks that go into effective split-testing can be made easy with this app called Split Test Monkey.
The information in the guide is helpful if you are doing or
thinking about doing split testing.
But yes, they want you to buy the Split Testing app, and yes, those are my affiliate links.
There is also an additional offer (but not required) that allows you to create multiple automations within
a single split test. It looks pretty cool if you are looking for a little more of a hands-off approach.
This is version 3 by the way. So the folks behind the curtain have been doing this for a while.
Check out the demo video and the rest of
the details on the offer page.
