I've found that the algorithm can be extremely volatile for some things and barely react to others. I watch half of one video by a 'pop' youtuber like MrBeast or LazarBeam and that's the only recommendations I get for a week. Likewise, I can spend hours and hours listening to more passive content like music or long-form documentary style videos and I barely see any bump in that kind of content recommended for me.

The most effective tweaking methods to the algorithm I've found is just subscribing to people who cover a genre I want to see more of and then watching videos from their videos recommended section.

I'm perpetually confused by YouTubes weights for choosing recommended videos.
