Admin, Editor, Moderator . . . sound like the same thing to you?
According to Facebook, not quite. People you designate as Admins, Editors, Moderators, Advertisers, and Analysts have different levels of access to your business pages. Some are individual while others overlap.
This chart breaks it down for you. Admin is the highest level, able to do everything from manage page roles / settings to create ads and see who posted as the page, so you can keep tabs on who's actively posting about what. But don't worry, this information is only viewable to Admins on your page – no other Facebook users will be able to see this information. Editors have almost the same power, though they aren't able to add or remove the page or its admins; access declines from there.
