Well, there is too many affiliate sites you can join and start making money from them by promoting their products or ads or services. you get % percentage commession only on sales.
Here is some popular affiliate companies
The Amazon Associates program has historically awarded affiliate commissions on a volume-based model. The more you sell, the more you earn. It started around 6% and went up to 8.5%.
The eBay Partner Network (EPN) is another cool affiliate program that’s been around for a long time, and plenty of marketers have made good money with it.
Target.com may be the best overall replacement for people looking for alternatives to the Amazon Associates program.
Jet.com was (in my opinion) overhyped as the “Amazon killer” when it was released. As ridiculous as that was, they are one of the few online retailers who’s competing with Amazon in a business model that’s similar to Amazon.
And there is too many more here.
Hope this can help you in your search.
