Keeping an eye on who likes your Facebook page is always a good idea. Knowing who is liking your page and when is helpful to determine how often new people are liking your page, possible places they may have come from or to see who you know from other networks that is getting to know you better on this channel.
This feature has always been available but it just moved and freaked a few of us out for a minute.
Previously if you clicked on the # Like This link it would show you the list of the people that like your page. Now if you click on that it brings you right to your Facebook Insights (weird).
New(er) way to see who likes your page
The first thing you need to do to see who likes your Facebook page is to Use the Page AS your page and not as yourself.
Now instead of looking to the left column, look right up in the blue navigation bar. those icons of people are now where you can see who has likes your page. The red notification lets you know how many people have ‘liked’ your page since you were last logged in this way and looked at who has liked your page.
By clicking that people icon you can see who has most recently liked your Facebook page. If you click on See All you can view the full list and scroll through your fans using the scroll bar on the right hand side.
There you go. Now you can see who is liking your Facebook page!
