As an affiliate marketer, you help product owners who has an affiliate program to sell their products. Basically, you sign up to their affiliate program, and they will provide you with your affiliate link. Once you have that link, you can place it on your website, social media or wherever. As Long as you are speaking to the right audience, people who are in your niche (people who are interested in what you promote), and they buy a product through your affiliate link, you will earn a commission.
If you add up all the services you get, the premium membership is a steal. For example, you’ll notice they include unlimited keyword research with a membership. Other paid keyword research tools sell for $49 or more just by themselves. Add in website hosting, and there’s another $10 / mo. Add on the website security package, and there’s another $10 per month (I’ve paid as much as $29 / mo just for website security). Just based on those things alone, Wealthy Affiliate is a great deal with all of the resources and tools you need in one convenient place. Not to mention all of the training, tutorials, and support that is included with the membership.
