There are different ways that you can make money on Pinterest. The first thing that you can do is to create a Pinterest-based blog. Make sure that you will only write content that can be considered to be helpful and relevant to people who may be reading it. You can also create some boards that may be related to the content that you want to write.
Make sure that you will organize them properly so that people who will follow you will also know which boards they should follow. You can also join some group boards if you would like to get noticed more by people. The more famous your content becomes, the higher the chances that you will start making money from this platform.
