>>96047674If you are uploading for archiving purposes - one long video.
If you want to get some traffic/impressions/new subs - in parts.
More videos = more chances to get picked up by the algorithm. Don't be discouraged if you get 0 views. Also nobody really watches playthroughs anymore, when you have actual livestreams.
I saw a vtuber on twitter and checked his youtube channel link. I wonder what you need to do to get completely ignored by the algo but as you can see people with such numbers exist. Youtube is very random.
