Monetizing review website

Hey guys, I thought this would be a relevant question to this thread. If this post is completely irrelevant to it, please let me know and I will do my best to move this to a different thread. I have a review website that I've been working on for quite some time, the niche is a bit irrelevant as of right now since I'm in the process of doing more SEO for it. I'm curious as to how I would go about monetizing it? I don't want to use Google Adsense since the margins are quite low, the goal of course isn't to make the most money. I care about my niche and want to help my consumers more than I want to make money but at the same time, I'm a bit clueless on how to properly monetize it to its fullest potential. Any advice or suggestions would be really appreciated. Thank you for reading.

Easy answer, Amazon affiliate

But what if my niche isn't really selling anything specifically?
Let me give you an example, it's a review website like Yelp for businesses. But not exactly except I'm not reviewing businesses or products. I'm a total noob at this stuff so feel free to tell me how idiotic I am.
