Yes, Keyhole tracks data from all public Facebook pages. This means that you can collect posts from any public Facebook page that you specify, and collect data around any #hashtags, keywords, URLs or @mentions that those pages publish.
Please note that we are unable to track data from personal Facebook accounts. Facebook only allows third party products like Keyhole to track posts made by public pages.
This limitation came about on May 1st, 2015, and Facebook no longer provides post-level data through their API. This means that terms such as hashtags can no longer be tracked across all of Facebook’s platform or pulled from posts made by personal accounts. This is an issue that affects all third-party analytics products. Please see our blog for further details.
Public pages can be tracked as Account Trackers as well.
