Amazon does not have a specific traffic requirement to accept you as an affiliate. You do not need a high amount of traffic to join. However, Amazon will review your website or content to ensure it meets their standards. You should focus on creating quality content that attracts visitors. Amazon wants to see that your site has real traffic and engagement. Once you start promoting products, you need to generate at least one sale within the first 180 days. If you meet this requirement, you can stay in the program.
