Twitter, an online social networking site that claims 11 percent of the online audience, is making headway into the corporate world.  Even large companies such as JetBlue and Comcast are using Twitter as a marketing and customer service tool.  But before you sign up and send a "tweet" into cyberland, there are a few things you should consider.

1.    Is your target candidate or client on Twitter?  Twitter's demographics are, urban, 30 something, technology savvy males with an undergraduate or graduate degree.  To find out if your target candidate or client is on Twitter, go to Twitter and search for keywords relevant to your specific needs.

2.    What are your Twitter expectations? Do you want to use Twitter to gain more clients, find candidates or do you have some other goal?  Whatever your Twitter expectations are, it's best to do a little research before diving in head first.

3.    How will you measure you return on investment (ROI)?  As with any online social networking site, it can be easy to get sidetracked and lose sight of why you signed up. Once you determine what your goals are for Twitter, you need to create a system that will measure your Twitter ROI.  For example: How much time do you spend on Twitter? How many new clients/candidates have you gained from Twitter?  Is Twitter more/less effective than other marketing or customer service tools?
