> I periodically check out YouTube while not signed in

I wonder if that actually works... It still tracks location, obviously Cookies (which you probably delete for this) and possibly a lot of other things. Maybe YouTube even maps your IP address to previous logins and uses that information "just slightly" in order to not throw you off...

It’s seems to work pretty well, based on some non-scientific testing most of the suggestions is content similar to what’s on their trending page, which is what I’d expect.

But I’m sure YouTube slowly but surely starts building a profile while in incognito to try and capture your eye balls.
