Search history including Google search history, I’ve found.
I also completely believe that YouTube correlates via IP for at least not-logged-in views (or at least tries to associate to accounts even if they've never logged in); I get bleedover to my iPad from my completely disassociated PC but not my Mac that’s logged into a different account.
(Also maybe I put too much effort into tailoring my own YouTube recommendations, but 99% of the time when they start going awry, I have a pretty good idea what triggered it. Random coincidences don't happen...)
- samspenc 4y agoLike others have commented, I too am very certain Youtube uses IP address. My family and I are behind the same cable modem, and oftentimes my family's Youtube "related videos" will start popping up in my Youtube home page, and vice versa, even though I have no interest in or have watched those videos. Interestingly, I seem to recollect this happening only in the past few months or so, maybe a feature they turned on recently?
