For instance, I've learned that although Facebook live videos are pushed by the platform and can have a wider reach than posts with text and a photo, on average people only watch them for about 10 to 20 seconds. And I have found that to be true for not just brief videos, but live broadcasts that go on for a half an hour or more.
So when you look at the high level numbers, it appears that your live video blew everything out of the water. But when you dive deeper you see that its ability to connect with followers is average or even below average.
It can still make for nice content, but limit how much you rely on that.
