Whether it is:
Free YouTube marketing.
Free article marketing.
Free traffic from blog commenting.
They tell their students that it is not worth it to pay for ads and they tell them that not a lot of people are doing these free techniques so now it the time to take massive action.
People are also taught that paid ads is just too expensive and they will not get a good return on their investment.
So they take massive action with free marketing and then 6 months later, they made 1-3 sales. (Sometimes even sales)
There are other mentors out there, and I am not going to name any names here, that tell their students and affiliates that if they want to get the best results and earn money FAST, paid ads is the way to go.
They are RIGHT.
Paid ads is fast and easy. If you do things right, there is a good chance that you will see positive results in a matter of a few hours. Whether it is leads or sales or both, paid ads BEATS THE CRAP out of free ads.
Even if you start small with paid ads, start right now.
Test different places to see what works best for you and you will get traffic that will sign up on your list and buy what ever products you are promoting to them.
