1. Google+ Hangout Tips from The New York Public Library
Create a Google+ profile for the Gmail account that your YouTube
channel is connected to and make this account a manager on your
Google+ brand page
Use this account to launch the hangout on air from your Google+ page
Leave ample time to familiarize yourself with the location from which
you’re broadcasting
We found that a two-hour prep is just about the right amount of time to
hook everything up and test
If you’re broadcasting from the same city, it’s a good idea to be in the
same building
Try to use high-quality external cameras and microphones if you can
Use a Google+ event to set up a home for your hangout where people
can leave questions and comments ahead of time
Take advantage of hangout apps, such as the Hangout Tool Box, which
allows you to add lower third graphics and logos, control that sound of
all participants, and more
Find a good topic that ties your brand to a current event, pop culture,
product, movie
Promote the hangout everywhere – remember that your customers
don’t need to have a Google+ account to watch the hangout on air
Have enough staff on hand to deal with technical setup to keep talent
comfortable, run the hangout smoothly and keep an eye on the social
feeds
