Hi guys,I know that my question might be somehow niche related, but anyway, I am wondering a YT video which promotes a CB product for how long it can bring money and what will happen to it after a while? In other words, regarding to the sales what will happen after say 4, 5 or six years? The number of sales increases or decreases? Or maybe it goes to zero? One of my YT videos brought me money since last year. Now I am wondering what will happen to it in the next 3 or 4 years? Can I expect more sales (because of the natural ranking -views and so on- of the video) or I should expect less or zero sales? Any experience? What is your experience? Is there any guy here who has an aged YT video which yet is able to bring him/her money? Thanks.
