ClickFunnels launched its platform version 2.0 in late 2022. This course here is using ClickFunnels Classic (the predecessor).
Basically, it doesn't even matter if you use ClickFunnels Classic, ClickFunnels 2.0, or even another sales funnel builder platform such as Builderall, Kartra, or Systeme.io.
Even though all the interfaces and usability of the various platforms differ, the content of this course is still relevant and beneficial to you to get a fundamental understanding of sales funnels strategies that help you grow your business.
Since the recording of this course, my view on ClickFunnels has changed and that's why my personal favorite all-in-one marketing platform is Systeme.io, which I switched my entire business to after 4 years on ClickFunnels Classic.
