This video provides a detailed demonstration on how to create and manage multiple YouTube channels under the same Google account and email. The tutorial starts from logging into the official YouTube website, guiding users step-by-step through the profile menu to the settings page or YouTube Studio. Then, under advanced channel settings, you'll find the option to 'Manage YouTube accounts.' From there, on the account management page, you can locate the 'Create a new channel' or 'Manage your channels' option. Clicking this will allow you to create a new channel and name it (which can be changed later). The system will automatically create the channel and redirect you to the new channel page. The video also shows how to quickly switch between multiple channels by clicking the profile picture in the upper right corner and selecting 'Switch account' to view and choose all your channels. The entire process is simple and efficient, suitable for creators and marketers managing multiple YouTube channels, helping users manage multiple channels without needing additional email addresses.
