This document provides 5 tips for using Google+ Hangouts on Air for businesses: 1. Plan Hangouts 6 to 8 weeks in advance to build an audience of 100 or more through marketing. 2. Don't rely solely on RSVP functionality; use tools like Eventbrite to collect leads for follow up and analytics. 3. Use adequate lighting and an external microphone to ensure good video and audio quality. 4. Connect via Ethernet instead of WiFi to avoid connection issues during live events. 5. Start with a private Hangout to test connections before enabling the public live stream.
