Here is what it says (this is via Facebook from the link above)
If I don't promote my post, will the people who like my page still see it?
Nothing has changed about how your posts are shared with the people who like your Page.
A lot of activity happens on Facebook and most people only see some of it in their news feeds. They may miss things when they’re not on Facebook, or they may have a lot of friends and Pages, which results in too much activity to show all of it in their news feed.
If you don’t promote your post, many of the people connected to your Page may still see it. However, by promoting a post, you’re increasing its potential reach so an even larger percentage of your Page audience and the friends of those interacting with your post will see it.
I was somewhat excited about the possibility of being able to promote giveaways or upcoming craft shows. Well that is not a possibility yet for me. Seems you have to at least 400 likes in order to promote. So I am going to be on a campaign to get more likes. If you haven't liked my Facebook page yet please do so.
I hope this clears up some of the confusion out there. I am not totally thrilled by this change, but I am hoping maybe the promotion campaign might help.
