This is an example, but the premise is the same for most similar sites, so I'm using generic terms.
Website X gets 100 advertisers to place ads on their sites.
Website X gets paid by these advertisers every time a person comes to their site and signs up for a program or buys a service. The products/services are sometimes free, sometimes only a few bucks, and sometimes expensive. For the free and cheap offers, the reason Website X still gets paid is because, on average, the person purchases more products or services from the advertiser after the free or cheap purchase.
How does website X get people to come to their site and sign up with their advertisers?
They offer cash or prizes to people for signing up with a specified number of advertisers, and then referring a certain number of other people to do the same thing. Overall, the cash and prizes given out are worth less than the money brought in from the advertisers, so they make a profit.
So where do you come in?
I have signed up with a few of these websites like Website X and completed some offers, but I need to refer a few people to get my prize. I will pay you to be my referral.
I will pay anywhere from $5 to $30 depending on the site you want to do. You can do just one site if you want, or you can do more and make more money. If you do well enough, I'll show you how to get your own referrals and make even more.
You will need a home computer with internet.
You will need a valid credit or debit card. IMPORTANT - This may scare you off right now, but I'll explain why you need it, and why it's safe, and you've probably seen similar situations before. Many of the offers are free trials that you need to cancel if you don't want to keep them. They get your credit card info in the hopes that either you will forget to cancel or you will like the service and keep it, in either case they go ahead and charge you. If you cancel before the end of the trial, you are fine. ALSO, noone is ever allowed to charge your card without your consent and almost all major credit cards allow you to dispute unauthorized transactions and have them removed in case you're that worried about it. But if you follow the rules, you'll be fine.
You will need a paypal account. It's easy to set one up if you don't have one already.
You will need some very basic computer and organizational skills to help you understand the process and to make sure you do everything correctly to get paid.
I will prove that this is legitimate and that I am legitimate. We can talk via messenger or over the phone.
Email me here if you want more information. I'll pay you $10 for your first trade, and its an easy one that will probably take 30-45 minutes at most.
Here is a "payment proof picture" from someone I was a referral for.
