How Facebook EdgeRank works?

Jay Baer explains on his website how Facebook EdgeRank works:

“if you’re truly passionate about something, you’ll most likely click and/or comment on the status updates published by that something, giving Facebook a hint that they should definitely show you more of that publisher’s musings in the future, by automatically pushing it to your Top News stream.”

According to Chris Sietsema 1 in 500 updates on Facebook make it to the news feed.

The question is what to do to generate more traffic and how to understand that algorithm? Mari Smith during her webinar at social media success summit explains that:

• educate your friends — generate more feedback from your connections by creating, e.g: ask questions, share information others may find interesting
• don’t publish everything at the same time or in short period of time. Create a schedule: once, twice a day or three times a week – whenever is the best for you and your friends/fans.
• use variety kinds of Facebook content –> photos, videos, links, status updates, apps, questions, etc.
