How many of your Facebook Friends are you really reaching?

Not as many as you might have thought. At least not according to this wonderfully informative blog post by author Jody Hedlund, detailing how Facebook uses a calculation called "EdgeRank" to determine which of our Personal account and Page posts show up on our friends' news feeds.

Here's the kicker - you can PAY to promote the post and have it appear on more feeds.

Are you surprised?

At least I finally have an explaination on why some friends' posts don't show up on my feed, but are visible if I actively search out their account. Silly me, here I just assumed I had missed their post in the never-ending flow of info.

Really, check it out. Jody has written a great post, and has including several links for those who would like to learn more.
