Awesome answer, Julie! I think the three words you chose (entertainment, empowerment, & education) just about perfectly sum up what an alluring Facebook page looks like to me.
In the end, it all comes down to the level of value the page presents itself as having. Also, I have to get the feeling that the page is there for what its audience wants. This means I’m usually deterred by a page that’s clearly just concerned with promoting its own products and/or services.
Hope this helps with your research!
