Let’s talk Facebook, shall we? Chances are pretty good that you can be counted among the 1.3 billion monthly active users of the social media giant, and there’s practically no other website that contains such a breadth and depth of personal information.

Put all your social media accounts on a short leash which will help you manage your digital footprint. Look into Facebook’s proprietary privacy tips or get the works from Lifehacker.com with its “Always Up-to-Date Guide to Managing Your Facebook Privacy,”

Then delete the ones you no longer use. That myspace page you signed up for? Don’t just forget about it–find it and delete it.

Don’t overshare. As much of an alien concept as it may be to students these days, the only sure-fire way to avoid digital footprint trouble is for them to keep quiet about anything they wouldn’t want to share with everyone in town.

This includes usernames, aliases, passwords, last names, full-names-as-usernames, pictures, addresses, and other important information.

You may be surprised what you find.

When you link your Facebook or twitter account to that new site (whatever site that might be), you may not realize, or care at the moment what you’re giving it access to. It’s usually safest to use a secondary email address to sign-up for new sites rather than granting this kind of access.

Whether you’re communicating with someone new, or signing up for a new social media platform, it can be useful to have a secondary email address.

That said, you don’t need 12. Keep it manageable.

Every time you send a message, post, or picture, you’re publishing it the same way BBC does a news story. And the internet never forgets.

There’s another side to your digital footprint, too — it’s not always information that you choose to make public. Remember: Privacy controls or no privacy controls, Facebook still records and uses every scrap of information it gets to better determine its users’ marketing demographics.

Google pulls the same trick with search and browsing habits. If you're logged into their Google account, the service tracks every keyword you search, every Web page you visit and every time you visit YouTube.

There are ways, however, to control the bits of deep data that we leave strewn around. First of all, even though Google is practically an official synonym for “Web search,” it isn’t actually the only game in town. Less profit-motivated search engines like DuckDuckGo.com and Ixquick.com may take a little getting used to, but they do make explicit policy of protecting users’ browsing privacy.

A host of browser extensions and app add-ons can also limit the surreptitious capture of personal information. Disconnect (Disconnect.me), DoNotTrackMe (Abine.com) and Ghostery (Ghostery.com) are examples of cross-platform extensions that block tracking cookies and give users control over site scripts.

Just remember everything that you post, tweet, comment or like is going down on their permanent record. Honestly, everything!

This is more of a security thing, but the worst kind of footprint is the one you didn’t make that contains all your sensitive information. It’s too much work to remember 50 different passwords, and every site has their own unique rules. Until someone solves this problem, the best solution is likely a password keeper.
