Check-in numbers on Pages will be updated in the next few weeks
Recent notice from Facebook:
We are revising check-in numbers on Facebook Pages to give you a more accurate picture of how people are visiting your business.
Among these changes, previously, if an individual checked into your business multiple times, each check-in was counted into your Page’s total check-in number. Now, if someone checks into your business multiple times within a 12-hour period, that action will be counted as one unique check-in.
In addition, when people tag their friends at a location and upload a photo, those photo tags will be counted more holistically. For example, if 20 photos were uploaded to an album at a specific location, we’ll now count that as a single check-in. If Jessica checks into a location and tags five friends in the photo she uploads with her check-in, the total check-ins number will be six — Jessica plus her five friends.
