Your YouTube channel can be new, old – doesn’t matter. What matters is ARE THOSE VIDEOS WORKING FOR YOU?
If you have videos longer than 3 minutes, you might want to consider going back and time-stamping key points.
I do that.
You may want to consider ANNOTATIONS – this is where notes, hot spots can be added throughout your videos for a call to action. They can link to your YouTube channel, a subscribe link for your channel, a specific video – if you have a series and want them to view the next one, a play list or your Google+ profile or page. I can do that for you. While I’m in there, I can check keywords, descriptions of your YouTube videos, playlists and your channel art and clean it all up – as well as connect it to your Google+ page or local page.
