If you prefer to upload your video to YouTube first, you can do so share it the other way round – with Google+.
YouTube is automatically integrated with Google+.1. Click the YouTube “Upload” button and a window will open to the left.
Press the big Up Arrow button, and select your movie file from your PC.
2. Type in tags (adding a comma to separate them); choose the best category… and make sure your movie setting is “Public”, in order for it to be linked with Google+.
The “g+” radio button will be checked by default for AutoShare – meaning any video you post on YouTube will automatically be shared on the social networks checked.
You can also check the buttons for Facebook and Twitter too… or deselect them all, if you prefer.
Sharing your video link on Google+ will place it in your stream. (If it doesn’t, share the link directly in your Google+ feed.)
Your Public videos will still be viewable on YouTube and from within Google+.
