How can I promote my videos on youtube?

You can post video responses to other relative videos that have a high amount of views. Use a lot of key words that are relate in any way to your video. Be creative with key words. Don't just use the basic descriptions the directly relate to your video. Use key words in your title too. Don't worry about how it looks, this helps also. Here is an example Comment more on other people's videos. Instead of typing "cooking" type "How to properly prepare make a Falafel". You could also add the ingredients as key words. The more visible you are the more the more you will get views. Add channels you like as friends. Create playlists and make them public. Set your channel so that people will see your activity like when you add a new video or make a comment. People tend to pay more attention to the channels that seem active. Post links from other sites that allow it.
