How, and where to promote your youtube videos?

- Google+ - join groups and communities related to the videos you put out and share them on the communities- probably the most effective method on this list.
- Forums are another thing. (Example: Go to a Minecraft forum whether it be the official site or popular fan site and post a Minecraft video you did in the respective catagories)
- Jasmine has things nailed with other social sites. I've just only have ever used the two above methods and since then, my increase in subscribers has doubled. Facebook, instagram, twitter or maybe a blog Maybe forums relating to your video subject.
