Simple question, what is your thoughts on commenting on YouTube videos? does it raise traffic to your channel?
Based on personal experience, it does raise a little traffic. I've commented on a lot of other small youtuber channels and the next day, the youtubers I've visited actually checked out my videos and left comments.
Just be careful with your words.
If you comment saying, "Hey love your personality! sub 4 sub?"
Then they will most likely ignore you.
Even saying, "Great video! If you have time, I also own a channel if you want to check it out.", is not a good way to get their attention.
I always steer away from asking them to check me out. Just drop hints that you own a channel. And also, actually check their video out. It's not that hard to do.
"I really thought this video was helpful. Now I know what products to buy next time! I really enjoyed this video and hope to see more from you. Keep it up! Also, what editing software do you use?"
- Yes, it's a little bit of a lengthy reply... but it's genuine and it doesn't seem like you're begging for views.
