Unfortunately, the widely held notion that your so-called "friends" see your posts on Facebook is a myth. In test posts of thousands of my Facebook friends, you'd be lucky to reach 1%. Facebook is NOT an email list! - it is more like a stream that either you catch or don't. For you to actually reach your friends means paying Facebook to "Boost" your posts, they're not going to do it for free.
Don't believe me? Do a test. Make a post asking your friends to simply "Like" it if they saw it. Take the "Likes" and compare to your friend count total. Prepare to be unimpressed.
