Check out what competitors are offering and how they structure their affiliate programs because that'll be a good place to start. It's also what your affiliates are going to be comparing you to when deciding whether to endorse you or someone else. Remember, your affiliates have many options of products/services to represent so they're going to want to choose products that convert well and offer a decent payout.
Cloudways affiliate program is quite a profitable program. With flexible commission structures (Slab, Hybrid and Custom), you can earn $5K and even more every month. The performance-based Slab structure starts out at $50 per sale and depending on the number of sales made, reaches up to $125 per sale. The hybrid plan contains an initial $30 payout for each sale and a recurring commission of 7% for lifetime. The custom plan, designed for super affiliates, is a combination of the two. Cloudways also provides a comprehensive dashboard for performance reporting that helps affiliate marketers optimize their campaigns.
