How can I see who had liked my page on Facebook?
This question is very frequently asked on forums. It is one of the first questions from everyone who has created Facebook Business Page.
If you are page admin, then the solution is quite simple:
1. Open your page and click “Settings” on right side
2. Click “People and Other Pages” on left side.
3. Change filter to “People Who Like This Page” if necessary.
Note: Facebook makes changes on their website all the time and the above-described solution maybe won’t be available in the future.
