The best affiliate programs to join without having a website are those that allow promotion through social media or other platforms. Amazon Associates is a popular option that works well on Instagram, YouTube, and TikTok. ShareASale and Rakuten also offer affiliate opportunities that can be promoted through blogs or social channels. Fiverr’s affiliate program allows you to promote services on platforms like YouTube or Facebook. ClickBank offers digital products with high commissions, which can be shared on social media. You can also join affiliate programs from companies like Bluehost or HostGator and promote them through your social media. These programs work well even without a website.
