So let's say for the sake of it that I make videos about Lions currently.

But I started out making Zebra videos, then switched to Leopards, before moving to Lions.

99.6% of my views in the last 90 days are from my Lion videos.

I have 3 distinct questions:

1. My Zebra videos are unlisted, should I private them so they get removed from people's watch history and make my focus clearer for the algorithm?
2. Should I private my Leopard videos also to 'unconfuse' the algorithm? Or unlist them so they don't cannibalize impressions at least? They aren't really pulling any weight.
3. I also have episodic Lion videos that I then compiled into one big video - and the episodic ones are basically dead while the big video pulls good views. Should I unlist the episodic ones so they don't cannibalize impressions?

Or am I just wasting time thinking about this...
