Many successful affiliate marketers have a basic 2-page website and an email marketing system that does their affiliate promotions on autopilot to make passive income. One page is a landing page that promotes a lead magnet to entice people to subscribe the email. Once subscribed, the visitor is sent to the second page, that often has information about an affiliate product.
You can use social media to share your blog content with affiliate links, or you can directly share your affiliate links. Note, that you should give an indication that the link is an affiliate link when you post to be transparent and not annoy your followers. People don't want to be sold to all the time, so posting affiliate links should be interspersed with non-affiliate and non-sales posts.
