Google Hangouts is the best when it comes to live broadcasts. You can stream, record, bring in guests, and run a Q&A session with a live audience. The problem is, all these happens in your Google+ account, not on your own site. To solve this, we need to put Google+ Hangouts session in WordPress.
The first thing you need to do is to go to Google+ Hangouts on Air and click the Hangout On Air button.
Then a popup will appear asking for your details on your Hangouts on Air. Fill in the required details.
