Facebook “Reach” is simple; it’s the number of unique people who have the ability see your post. While “likes” are important, you won’t get ‘em if people don’t see your posts. So, your Facebook reach is calculated by the number of your “likers” who see your post PLUS if they like, comment or share your post it’s the number of THEIR friends and followers who could see your post.

Bottom line? Post interesting sh*t so people will interact with your post and multiply your reach.
