Most marketers out there dont understand what a funnel really is. I mean the Product you want to market needs to be ready to convert aswell, so this point is also really important. A strong budget most people also forget, you cant spend $10 and make $100 nobody can do this. You need to spend around 40% from your budget to make 60%. The 'shady' trick most companies do is promoting with an affiliate link, yeah cool i make $1000 and the company owner makes $10.000-$20.000 its a old strategy to trick marketers, its a quick money grab, but in reality you the 'dumb' one. Why do you think Bezos company makes $500b per year? Everyone you see online promise the big buck, uses this exact method which i told you and they will do this in 100 years... Nobody and i mean nobody will give you value for free there is always, always a 'backdoor' always.
