Take advantage of affiliate program freebies when available. Many affiliate programs provide free printables, guides, webinars or other lead magnets designed to get potential customers in their sales funnel. As an affiliate, you can share these freebies with your audience using your affiliate link so if they eventually make a purchase, you’ll earn a commission, but if they don’t they still get value upfront.
If you’re running an offer that’s never been run before like your own product or something, then yes, you’ll need a decent sized budget to get to a break even point. But if you’re running affiliate offers that other people have been running for a while then all of that research and testing has already been done. Just use a spy tool like AdBeat and match your campaign to theirs.
Now, this isn't about some get-rich-quick method here. If you want to get rich quick, forget about trying to do it on the internet. Sure, Facebook ads are all the craze, but without a serious understanding of the mechanics behind sales funnels and conversion optimizations, which only comes after years and years of in-the-trenches work in the internet marketing field, you're largely wasting your time trying to "get rich quick."
The best review sites (like BestReviews.com buy them all independently and test them without bias) but anyway, you could always review products you already own and use (recommended) or just not focus on product reviews at all, it's just one of 1000's of ways to make money as you should be able to see from the post that shares endless examples of ways people make money other than reviewing products.
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
