There are many better-paying affiliate programs, but the one that pays the highest has to be in the hosting niche. However, because the upfront payment is high, they aren’t always paying a recurring commission.
In some cases, the commission is 1.5x to 2x the amount the customer pays.
However, if you want to take the overall amount you can make as an affiliate, it has to be the recurring commission affiliate programs.
Furthermore, suppose you want to consider the conversion ratio, then for me. In that case, it has to Amazon affiliate because the amount of traffic I send to Amazon and the number of sales I see is a lot higher.
