Have a fully charged smartphone battery
Live video can use up to 1% of your battery for every minute, so a 60 minute tour could drain 60% of your battery.
Greet your guest
Offer a warm and sincere greeting and use the guest's name. Introduce yourself, and let the guest see you on camera. It's OK to wave.
Start the visit with a great view
First impressions matter. Plan ahead and pick an interesting location to start the tour.
Anticipate your guest's needs and fulfill requests
Get a feel of what your guest is looking for. Is she chatty or quiet? Always remember that you are not the focus of the visit. Does he want you to be a traditional tour guide and have you point out things? Or should you be supportive, fading into the background, as the guest draws the focus and movement?
Stay aware of your surroundings
It's easy to get caught up "behind the lens." Stay aware of the people around you, and be considerate. Your guest can't see the things you can see, and may ask you to do things that don't fit in by mistake. And don't trip!
Take great photos
When a guest asks you to take a photo, politeness will push you to take the photo rapidly and return to the guest. But that's not the way to do it. The photos you take will be kept and remembered by your guests for a long time. Take your time, and take great photos.
Wrap up the tour, and offer a fond farewell
Confirm any arrangements for sending pictures or souvenirs. Give a warm good-bye and use the guest's name.
