I'm going to be honest with you. And probably a bit harsh. Note that this is not personal but that your site is
very clearly not good.
Basically, you put a bunch of trash games on a page. The effort you made is minimal. And so the result is not something that you can monetize. You cannot reasonably aim to make money for nothing.
The games themselves, as I said, are trash. They are the sort of games spammers use to put out hoping some poor soul will accidentally bite the bait and then distribute malware or whatever. Poor quality games, full of ads, and many of them don't even work. This is the shittier part of the internet.
Given those two points -poor content and very low effort on your part- I can't give you any advice other than tell you that this doesn't even look like a serious effort.
