Suggestions Advertising Released Game

I have published my game online for PC/desktop platforms. I am now aware that developers should accumulate interest in their game during production for a more successful release.

I’m finding it hard to get exposure from my own website, youtube channel, social media etc. It’s kind of like owning a restaurant and hoping that people passing by are hungry. A better Idea is to advertise your restaurant on fliers and interstate billboards that extend way beyond the location of your restaurant. In short, I’m looking for the internet equivalent to this. How would I go about advertising my game on popular websites and other author’s youtube channels?

Money isn’t an issue, I’m not currently trying to be profitable, just trying to get some exposure and feedback on my released game. Thanks in advance for your suggestions!
