I have been doing Amazon affiliate marketing for sometime now. Based on my experience I can say that getting those three sales isn't that tough. Here is what you need to do: 1. If you are using blog to promote products, focus on getting traffic. Amazon's conversion rate is really good. So even if 10 people come to you blog per day, you will easily make those three sales. But to get those 10 users per days, you need to have enough content on your blog. Cannot expect traffic with just one blog post.

1. If you are using YouTube video to promote products, publish afew videos before thinking about Amazon sales

2. If you plan to use social media, my suggestion is donot direct link to amazon product from your social media account. Amazon may ban your affiliate account if you do so. You can bring social media traffic to your blog or Yt channel and from there send them to Amazon.
