Your dashboard insights update every 24 hours. You can check out the Facebook reports on the lefthand side of your dashboard to see your day-to-day metrics like check-ins, page likes and impressions.
*Facebook reports all data to us in GMT. This means if you're on the east coast in the US, if anyone checks in to your page after 7 PM EST, the check-in will count towards the next day.
