First, let’s talk about the primary objective as an affiliate marketer: your goal as an affiliate is to deliver the right offers, to the right people, at the right time. You need to create a balance between what your vendor is offering, and what your customers require. In order to do that, you need a source of traffic and a good product or offer.
Also, if you own a website, encourage visitors to subscribe to your email list, so you can send direct marketing campaigns (with affiliate links!) to their inboxes.

Whenever you promote a product be upfront with your readers. Provide value and educate them. If you have personal experience with the product let them know that. But if you don’t, be honest with that too. Let them know the information they need based on research that you’ve done. Your audience will appreciate you being honest and will buy from you based on the trust that they have with you. Some of the links are affiliate links, meaning that I will make a small commission if you purchase a product or service by using the link. You get the same price whether you use our special link or not, and sometimes I’m able to get you an even better deal through my relationships! More info in my privacy policy.
When the excitement of getting a new blog dies down, most people start to panic when they realize that they have no idea how to start creating content. It's a common concern, but one that can be sorted out easily.
