15 Periscope best practices:
  1. Have the right equipment—a rig or a tripod, a full battery and a smartphone or tablet with the app installed—if you don’t have the equipment you can find it on Amazon
  2. Make sure your smartphone is fully charged
  3. Make sure you have wifi or a 4G connection from the place you will be broadcasting from
  4. Appropriately title your broadcast
  5. Have a call to action in the title so people know what to do or ask when they open the broadcast
  6. Share it socially with your followers and friends
  7. Be consistent with hashtags and other conversations or broadcasts you are performing at the time
  8. Hold your smartphone vertically — changing to landscape doesn’t re-calibrate the broadcast and you end up with a weird viewing angle
  9. Use the top 3rd of the screen—commentary will block the view of what’s going on if it’s switched on
  10. Flip the camera, if you are interviewing yourself or talking to the audience have the camera facing you—if you’re shooting a scene, make sure you flip the camera
  11. Be aware of mirroring—if you are filming with the front camera, text and other gestures will appear mirrored and make it difficult for the audience to see
  12. Ask questions of the audience—everyone loves to give their opinion
  13. Answer questions in real-time to avoid frustration
  14. Encourage positive feedback by asking your audience to double tap to agree if typing isn’t conducive
  15. Remember Periscope is a mobile-first application and that your broadcast will be global. With that in mind, you may get unusual questions—luckily  you can pause commentary and block offensive users.                                                                                                            http://blog.ketchum.com/15-periscope-twitter-tips/
