Is your online reputation everything you want it to be? Hiring has gone digital and Big Brother isn’t the only one watching you.

Eighty-three percent of hiring managers polled by ExecuNet (www.execunet.com) say they use search engines to check out a candidate before contacting the individual. And 43% say they have eliminated a job prospect based on something they found online.

“Digital dirt” is derailing job searches before the interview process begins. What can you do? ExecuNet, a business networking organization, offers these three tips:

1. Be alert. Google your name on a monthly basis to see what potential employers see.

2. Purchase a domain name to display your résumé, volunteer work and any other professional accomplishments, such as trade journal articles you’ve written. Search on GoDaddy.com to find out whether (yourname).com is available.

3. Prepare a positive story to answer questions that may arise about your past. For example, if you filed a lawsuit against a former employer, assume a search will uncover it, and be prepared to tell your story.
