Profile is an online representation of the physical location on the platforms.
A Profile on a platform is the representation of a given set of data related to a location, present on that platform. Each platform calls them in a different way - for example they're called Pages/Location Pages in Facebook or Venues in Foursquare.
Profiles usually show details like address, phone number, opening hours - and may also include information like user reviews or ratings.
Localistico automatically finds info about Profiles that could belong to your locations and help you group them together. All profiles found for search terms similar to your business are shown under the tab Locations > Profiles.
Each location usually has multiple profiles. You can edit the profile info by publishing the edited venue information.
