As soon as you build a significant community of followers, you need to keep interacting with them on a regular basis, through comments, social media, or your site’s forum if you own one. Ultimately if that part is not interesting for you anymore, you need to hire people to do it, or find moderators, etc… to do it for free. If they do it for free, expect them to leave regularly, so you have a constant job of “hiring” ongoing.
In addition to the noted jobs, there are many others that include monthly residuals. Use this rule of thumb: Industries that offer products or services that involve "pay as you go" contracts or agreements often pay monthly residuals to sales employees. For example, alarm companies selling ongoing home or business monitoring for a monthly fee may offer residual income to those who sell this service. In some cases, jobs that involve referring prospects for services that continue month-to-month also pay residuals. Always verify that, regardless of the industry, a job you're considering does or does not pay monthly residuals. Never assume.
My advice for beginners – especially beginner bloggers with new sites – focus on your site content and traffic for a while, then add your Amazon links once you have a little traffic. So many beginners focus on making money from their links and sacrifice their content building in the process. Without good content and traffic you won’t make much anyways.
