Monetization, ads vs affiliate mkt, pros and cons? I will not promote

I don’t have experience with affiliates but I understand they might be a source of income other than ads. Does anybody have experience doing so or would you recommend to stick with ads? I want to add them to my app. The ads are easy to set up and have been running for some time, so now I’m looking into affiliates for an alternative monetization strategy. I wouldn’t be having both at the same time, is rather one or the other. Thanks I will not promote
