The More People See Your Posts, the Better

You may not want to share your updates and other personal information with the whole world, but Facebook has kept the default setting as Public. It’s better for us if you share more, and we’re assuming that most of you aren’t going to bother changing your privacy settings.

Facebook Manipulates What Shows Up In Your News Feed

You may not see every post from your friends, and only a fraction of your friends may see all your updates. Facebook wants users to see posts that will keep them on the site the longest, so it moves up the posts that are the most liked, shared, and commented on.

Facebook Follows You Around the Internet

If you’re signed in to Facebook, we track you while you surf the Internet. Anytime you visit a page that has a Facebook Like or Share button, that information is logged.

Be Careful When Posting About Your Vacation

If your posts are set to be Public, burglars can see your status updates and figure out when you’re not in town. Insurance companies may also use posted information to raise a premium or deny a claim.

Big News? Your Friends Will Find Out

Posting big news like your engagement, the birth of a baby, or your acceptance to grad school? Facebook will know. We target those types of announcements by using something called natural language processing, and then make sure they stick around in your friends’ news feeds until the next time they log on.

Sharing Your Personal Info Can Help You

It may work to your benefit for Facebook to know a lot about you. For instance, if you ‘like’ the Old Navy Facebook page because you love to shop there, you’ll appreciate it when a coupon pops up.

You Can Do A Lot to Alter Your News Feed

Not seeing enough posts from friends you care about-and too many from those you don’t?

Set your news feed to sort by Most Recent, rather than Top News. Then add your favorite people to your Close Friends list and unsubscribe from any friends whose updates you’re not interesting in receiving.

Facebook Makes Money Off of You

Facebook earns revenue by selling ad space to companies that want to reach you. They give us demographics-the desired location, career, education level-and Facebook puts their ads on the pages of those who meet the criteria.

You Can Pay to Have More People See Your Posts

Really want to make sure your friends see your important news (you’re having a garage sale, for example)?

For a fee, around $7 to $10 a post, Facebook will move your update to the top of their news feeds.

Timeline Isn’t Going Away

Lots of users hate Timeline, but it’s here to stay for the foreseeable future. It’s a more effective way for people to share, it’s visually appealing, and brands love it because it gives them a better platform to market their business and show people who they are.

You Can Target Your Facebook Posts

Limit your posts to friends who live in your city, those who went to your college, those you work with, or allow everyone to view a post except your boss by clicking the arrow in the lower right-hand corner of the status update box.

Beware of Pranksters

Never leave your computer while you’re logged on to Facebook, especially if your co-workers have a sense of humour.

For a while, whenever someone at our headquarters did that, we’d write something like “I love Justin Bieber” as his or her status update. When that happened to me, I’d get e-mails asking, “Are you OK?”

Be Picky When Choosing Friends and Liking Pages

If you say yes to everyone, you’re going to see lots of things in your news feed you don’t care about, and you’ll have to take the extra time to filter them out.

You Can Make Yourself Invisible

Hide from all your friends on Facebook Chat by going to the chat box and clicking Go Offline.

If it’s just one particularly annoying friend that you want to avoid, click on his name in the chat window, hit the cog icon that’s in the top right, and choose Go Offline to [Name].

Some Information Can’t Be Made Private

Your name, profile picture, cover picture, network, gender, and username are always publicly available.

Noticed Fewer Fans on Your Favourite Facebook Pages?

That’s probably because the company has recently been cracking down on phony profiles created en masse by shady companies to boost a page’s Facebook popularity.

In a recent filing, Facebook estimated that as many as 83 million of its profiles are fake, though some are duplicate pages set up by real people.

Watch When You Like a Company, or Post About a Product

Your interaction might be shown to your friends as an ad for that company.
