As someone who had a bit of a YouTube hobby and is trying to get back into it, I've generally found that the algorithm brings me a larger audience than I would have otherwise. I've published three videos in the last 28 days, and my analytics says I've gotten 5200 views across all my content in that time. I have about a hundred subscribers. Search is still king, but 15% of those views have come from suggested. I've got a 7.8% CTR so it's suggesting it to quite a few people.
