Your channel is your personal presence on YouTube. Each YouTube account has one channel attached to it. A YouTube account is the same as a Google account, and creating a YouTube account will grant you access to other Google products, such as Gmail and Drive.Create your account or use your existing one. Add keywords to help people find your channel. You can add keywords by navigating to the Advanced section of your Channel Settings. Make sure that your keywords are relevant to your content.
Your user name can also work for or against you. If it’s short, easy to remember, and original, people will be more apt to remember you. However if you are using an existing account, you can always change your username by editing it on your Google+ account.
