From where I sit, your views are NOT average. They are hugely above average.
Not sure I agree with that. I don't think there can be a reliable average for a channel that is only 2-3 months old. Hell, my channel is not even a month old and by your standards I'd be way above your "hugely above average". lol...
My SEO score is now 100% and all requirements and suggestions are met. But right after doing this my views just hit rock bottom as in maybe 10 views in 60 mins. How is this even possible?
Anytime you change thumbnails, title, description, etc, you're
potentially causing an immediate stop to any organic discovery as your data gets updated in the YT algorithm. I've read where some videos after an update take weeks or months for views to start up again. I personally think for better or worse, get the SEO as good as possible BEFORE publishing. And then stick with it regardless, and if you have to update it, maybe only update at the most a few times a year.
"maybe 10 views in 60 mins" well, that's still 240 views a day which would imop would be fine for a new channel. We have to keep in mind, with shorts you can get 10 views or 10k views in one day. There just doesn't seem to be any stable pattern of discovery (with shorts) that can be replicated in a linear fashion. I definitely think shorts are worthwhile for any channel because it's probably the fastest way to seed your channel content and help train the YT algorithm, but after it's uploaded, move onto the next one. It's pretty much out of your hands if you get 1 view or 1 million views.
And fwiw... I'm seeing a pattern with the majority of channels I research. The ones that have primarily shorts seem to have a lot more views to subs ratio compared to channels with no shorts. So shorts can be great for views, but not so good for subs. Probably makes sense as I would guess the typical user watching shorts has a short attention span.
