Forgot to answer this. I started a FB page a few weeks ago for the channel. It's really not much use at this point, but I haven't shared it with my FB friends, at least not yet. If I did, I'd get a boost in folks subscribing to my page. Without sharing it with my FB friends, it's really just a placeholder at this point, and may be helpful if/when the YT channel gets more popular.To make it count, seems its a full time thing for most. I hear if you link everything to a FB, IG, tiktok account that helps? have no intention of ever joining so what would work against the goal perhaps?
I also have an Instagram account for the channel that I started maybe 6 weeks ago. I have about 20 followers, and I think 18 of them are really attractive women who just want me to pay a fee to see nekkid pics of them. Again, it's more of a placeholder at this point for if/when the channel gains popularity.
Bottom line -- if you don't have an IG or FB account, that's not a limiting factor. It will just help drive views and subscriptions once you get more popular. At least in my opinion.
