How to promote YouTube videos?

Sup everyone!

I need help promoting my YouTube channel. I won’t post a link so Fluther doesn’t take down my question, but I’ll say that I post feedback videos for Web services and products.

I need marketing advice on how to promote my channel. Aside from Facebook and Twitter, where and how should I go about promoting my channel? Are there any forums that focus on Web products and services?

Any marketing advice would help guys. Thanks a lot.
