Hi Andrey, it is definitely not for beginners who have no idea how to even make money online at all. If you have a business already, funnel hacks is definitely something that you should invest in. I would say that there are definitely better and more affordable options for beginners too. Paid traffic is a tricky thing, but Funnel Hacks actually break it down easily on how to do it quickly.
Prospecting and marketing are all the things you do to get people into the first of your sales funnel stages. Note that stages are broken into two or more steps wherever possible. A demo could be called a single stage, but in real life it involves a lot of things: contacting the customer, sending reminders, doing the demo, and then following up. Whatever your own sales stages look like, the support you need in managing them will be the same.
