Affiliate networks offer you access to multiple (and by multiple, we mean hundreds if not thousands) of individual affiliate programs. They basically work by simplifying the signup process - instead of applying to become an affiliate for a each product you want to promote, you simply apply to join the network and instantly have access to hundreds of different affiliate offers.
If you’re serious about making money selling things online, it’s pretty much impossible to not recommend Shopify. The platform gives you everything you need to get your online store up and running in less than a day including a custom domain, beautiful templates (so you don’t need design skills), secure payment options, and they can even take care of marketing and shipping for you. Whether you’re promoting your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
I absolutely see the value in affiliate sales (and Pay Flynn is one of the masters at doing this authentically and openly), but I got really turned off it when I saw a lot of bloggers I read and respect writing junky “How to set up a blog” posts that didn’t seem relevant to their audiences purely so that the could get the sweet Bluehost commissions in.
