Monetize Methods

I read a lot about the different methods to monetize on instagram.. but my question is how do people monetize there instagram accounts when they do a broad range of niches?


I understand doing a sub niches instagram accounts and monetizing them all through one cpa website/etc such as (lifting,healthyfood , workout routines, motivation quotes, etc) but i don't understand how people monetize there instagram accounts when they have multiple accounts in different niches


Can anyone comment or add their two cents?
