Free Benefits
Google isn't an online social network like the others discussed in this section, but it is integral to all of them.
Whenever you participate in any other social network, that participation is tracked by Google. If anyone searches on your name, Google will pull up all of your activity. This makes it easy for anyone to quickly see all of the things you're involved in, then drill down to the detail level with just a click.
Want to look like an expert who is on top of your game? Give Google something to work with.
Pay-Per-Click Advertising

Be Careful
Whatever you do with online social networking, you should always be aware that Google is watching. Make sure that your social activities are designed to work synergistically to help, not hurt, your cause.
