One of the way to make money on the internet is to build a downline. Most people don't realize how much work is required to get to the point of making money.
First of all, let's go into some sad truth. Most people will never upgrade in a free program. It's sad, but it's true. So, to make money you'll have to refer a lot of people. And not only that, but you'll have to get enough upgraded downline to reach the pay out minimum. Most will set it at $10.00, but some set it lower.
So, if you want to make money with downline in free program, you'll have to find a lot of people. And sadly, most will quit before getting their first pay out. When you quit with money still in your account, it's like if your giving that money to the owner of the program. That money is lost to you.
There's a lot of program that are Downline Builder only. They offer you to build your downline using their program. They choose what program you can build your downline in. Some even choose the best one (using their own method of analytic) and they offer you to build a downline in those only. I tried a lot of those. Even got a few ones that I upgraded into. And it didn't work much.
What I like to do now, is fill the donwline builder into program that are not a downline builder at first. As you can see a lot of Traffic Exchange do have a downline builder. I fill the downline builder in all the ones that I use the most and the ones that I'm upgraded with. Then, I go to the rest and fill the downline builder in them too. It's a lot of work, but I do beleive that I can be good. Because, you could get downline in lots of program for free. You just have to fill in your affiliate id.
To help me, I have created a notepad list of all the program I'm using with the affiliate link. And I get a new one, I ad it to the list. When I'm filling a downline builder, it's really fast as I don't have to log in all those program to get my referral id.
I would recommend first to use the downline builder of program that you are upgraded in. Then you can expand to all the program you're using.
