For TubeBuddy it's twice a week, once for a video and one a stream. On my personal channel I'm going for once bi-weekly to give me time to create. on my gaming channel it's once every other day, and each has it's own strengths and weaknesses
I currently post once a week on Saturday. I plan to post twice a week starting September 1st. Recording multiple videos in a week with young kiddos can be very difficult but we're all learning and getting better at it.
I am just new to YouTube but at this stage I am trying to post at least 1-2 videos a week.
My goal is to continue at that pace and then hopefully gauge what videos are most watched and work with them as my strengths.
