After being accepted into an affiliate program, marketers receive a unique URL that includes their affiliate ID. They share that unique URL with their subscribers, site visitors, and social networks via text links or ads. When someone clicks on that link, affiliate software records that click and any resulting product sales in the affiliate’s account. When commissions reach a pre-determined threshold, the affiliate is paid.
Depending on your skill set, you could easily make a few hundred dollars or even a few extra thousand per month. And if you have some money to invest, you could easily launch into a variety of day trading activities. Those present some risks of your original capital. But if you know what you're doing and you work to hedge your bets by placing stops and limits, you could create sizable upside with lower-than-usual risks.
