Hi Holamadrid, first off welcome to the forum glad to have you with us!!
Now onto your question. While nichjet.com does provide great value for what you can get in terms of a ready made website, making money with clickbank is just like any other affiliate program out there, and thus in order to make revenue you will still need to promote the website and get traffic to it.
Using the nichejet websites can help to cut down on the time, and efforts it takes to build a website from scratch and the site structure set up can also benefit you greatly with the ranking on the first page, however you should not expect to just mearly put one of these sites up and the money start to produce itself without some input from your end as well.
Hope my answer helps with your question on this topic
