Need some advice on whether to delete older videos or not
TLDR; over 100 unedited privated videos over 3 years old on a single video game possibly messing with potential growth on current content made on different games.
Ive been posting quite consistently for a couple months and seeing some steady growth on a channel that is already established and many years old. I have used this channel in the post mostly as an archive for some clips for my buddies and it to rewatch, but more recently decided to take content creation seriously and branch out on my own.
This channel had over 150 videos on it already, 135 of which were all Escape from Tarkov clips that were completely unedited. I have privated all of them. Whenever I post a Tarkov short form video it gets pushed into the algorithm for testing as you'd expect and many get some half decent engagement. However, the issue I am running into is that I don't focus on Tarkov strictly, and whenever I post anything outside of it, the video will do extremely poorly and get maybe 5 total views (if that) until a couple of more videos on the same exact game are uploaded. These games are not outside the genre entirely either. For example, games like hunt showdown, metro, stalker, and gray zone warfare. They just arent Tarkov. Each upload of these other games as well also always have the recommended tags as things like "escapefromtarkovbeginnersguide" which is strange because I have not uploaded anything in the realm of a "guide"
Are these privated videos messing with the YouTube algorithm that much even though they are very old? Would deleting them entirely even help the situation?
