Get more ideas for content by viewing youtube channels.  Look at the youtube video thumbnails and the youtube video headlines.  Do you have information related to the main topics in the youtube videos?  Can you come up with more content that is based in the main category?

Your content might not be directly related to the subjects of the videos, but there could be some slightly related content.  Imagine looking at youtube videos and coming up with lots of new niche content ideas.  Build up brainstorming sessions to look at the main concepts, but from a different angle.

How far away are the concepts from the youtube video from your own information?  What could be the connector content that bridges the gap?  Looking at youtube videos could be something that provides new insight into what people are thinking about.

Don't stop after watching the youtube videos.  Make your way below the video to read the youtube video descriptions and check the number of comments.  Are the videos getting reactions from people in the comments section?  Does the video have any comments at all?  If the video does not have any comments, are you going to be the first one to put a comment below the video?  

Discover new concepts and ideas on youtube and brainstorm new options for your own content needs.  New videos are getting uploaded to youtube all the time.
