Social media sites are all the rage these days - it seems that adults and kids of all ages have pages on Facebook.

But what most parents don't know is that more than half of all online sexual predators approach children through social networking sites.

And then there's the problem with cyber bullies, who often gang up on other kids when they log into their Myspace or Facebook account.

If your child has a page on Facebook, it should be monitored.

This should include email monitoring and chat monitoring, as well as recording materials posted on the pages themselves.

But many parents don't know how to monitor Facebook.

The best solution is to choose parental control software that specifically offers parents the option to monitor Facebook pages, and any other social media sites as well.

One key feature to focus on is complete invisibility.

Since older kids who know that they're being monitored are likely to have multiple Facebook accounts, or to simply use someone else's computer to send emails or engage in chats with someone that parents wouldn't approve of.

An invisible keylogger is important too, since this gives concerned parents access to the usernames and passwords that kids use to gain access to social networking sites in the first place.

Not all parental control software offers something sophisticated as Facebook monitoring, so double check and make sure that these features are offered before you buy.

We suggest you take a look at SpyAgent, NetNanny, and our favorite this year, WebWatcher.

All three offer parents the ability to monitor Facebook, along with a whole list of nifty monitoring tools that make parenting your kid when they log-on just a little bit easier.
