What makes an amazing channel trailer?

For My channel, I just took some of the funniest parts of other videos and made a montage. Gives people an idea of what my channel is about and what type of humor they are going to see from my other videos.

Number #1 thing I suggest. Don't give the viewer false information on what your channel is about. Be Honest. You want them to subscribe because THEY want to. Not because YOU want them to.
