A new page will open. Under your channel click create a new channel.
To create a new channel, you have to create a Brand Account.
This Brand Account can be a different name than your personal account. You can use any name but it is better to use your company or content related name.
After you choose your Brand Account name, you might be asked to verify your account via text message or voice call. If that's needed, enter the verification code you receive from google.
As you have verified your Brand Account, the dashboard of your channel will be opened.
To complete creating of your channel, customize your channel arts, such as channel logo, cover image, description etc.
That's all! Now start creating videos and upload them.
