We have been posting a new video every Sunday. While our channel is still relatively small at 2900, we are considering skipping this week to allow us more time to edit our next video. Are there any adverse effects for doing that and also, what is the best way to tell your viewers what you are doing? Post a short update?
Technically you will see an impact, but realistically it's kinda dependant on the channel and how you've set up your audience expectations and such.
I've never set any set schedule, and I've taken MONTHS long breaks that haven't overly impacted me. Naturally things have slowed down, but I believe once you get back to posting, new viewers will be there regardless if you miss a week or not.
Here's some of my detailed stats to show how short term and long term breaks can impact your channel, keeping in mind my channel is art, focused mostly on evergreen content, and has been around for 6 years, so I have enough content to let the channel idle on old content. If I were more consistant (I need to find an editor I gel with) it might improve, and thus taking a brake might be more noticable to my stats.
1 month pretty consistent uploads with a week break (the arrows indicate uploads
subscriptions gained over a year. You can see the amount of uploads doesn't deem to change the numbers (for me) much
my views over the space of a year. You can see this is more impacted by the lengthy gaps in uploads, but nothing that would really concern me.
and here's the new stats YouTube has given us for new and returning viewers.
So my channel is different to yours, so take what I say with a grain of salt, but personally my stats tell me, for my channel, missing content isn't the end of the world. But I also have 6 years worth of content to keep my channel afloat when life gets in the way.
