There are a ton of great affiliate programs out there, and this is not an exhaustive list by any stretch of the imagination. These are some of my favorite programs, and the ones that I personally use and love.
There are literally thousands of affiliate programs out there, but I encourage you to pick with one to start out, focus on that and stay focused on creating great content to market their products (we'll talk about that later)
Quick tip: When you're joining an affiliate program, do not pay to join them! I have only done this one time, and the program was a reputable one that represented a huge company that added the money they charged be right back to my account.
I've been working with bloggers since 2008, and I almost never recommend that they pay to join an affiliate program, I definitely do't recommend it to you. That's a good way to end up with your money gone to a scammer.
Your task today is to signup for affiliate programs. I highly recommend starting with ShopStyle Collective, because you can start Pinning things right away from their app without having to create your own Pins.
