They way you look and the image your create for yourself is very important. However, it actually goes much beyond physical appearance.
The Internet has changed pretty much everythign including the way we communicate. It’s more important these days that we be very very careful what we put on the Internet and how that can affect us – positively or negatively.
Employers have no boundaries and you have to be able to defend your reputation. It’s more than important these days in the age of the Internet that you BE CAREFUL.
This is scary ish, so what should you do?
One third of executives have never done a search of their own name, according to Execunet, a job-hunting website for senior professionals. Since others are checking you out, wouldn't you like to know what they're finding? Even if there's nothing embarrassing, there might still be a doppelganger whom people might mistake for you, or other material that clutters the career-enhancing results you want people to see.
If your name is especially common or associated with a better-known person (say your parents christened you John Kennedy), try Googling different versions of it to see which yields the least cluttered search results. You might add a middle name or initial, hyphenate, or switch from a full name to a nickname. Then use that exact version for your résumé, business cards, and any professional work you do—you'll stand out more prominently on a Google search as John Q. Kennedy.
Use networking websites like LinkedIn and Facebook, which allow you to list your education, professional history, skills, achievements, interests, and links to other websites that you choose. These sites are a good way to promote your professional chops in popular places where customers and colleagues are likely to see them. If you're jobhunting, schmoozing on a networking site is also less likely to draw the boss's ire or attention than posting a résumé on HotJobs or Monster, which are solely dedicated to hiring.Some alternative networking sites, such as ZoomInfo and Naymz, have less of a social component but make it easy for professionals to aggregate information that's already online elsewhere, such as a corporate bio, personal website, or published works. While you're exploring all the possibilities, make sure any bios that exist online—whether on your company's website or someplace else—are up to date and consistent with each other.
Make sure your online image is consistent across all your platforms. Use a tagline or a standout fact about yourself to “brand” yourself. Use it for your website, LinkedIn, Facebook, business cards, etc. You should be known as someone.
