Create a YouTube Channel From Google Plus
Once you have your Google My Business Page set up, it’s easy to create a YouTube channel from the Page Interface.
Just go to www.YouTube.com and click on your profile picture on the top right hand side. This will make a drop down menu appear. Once the list of your Google+ Business Pages appear in that drop down menu (you will probably only have one) , then click “Create Channel”
