I think there are (at least) 3 ways that members of this group may want to be found:
* if you are looking for a job, you want your resume to be found
* if you are looking for candidates, you want your job posts to be found
* if you own a recruiting business you may want your website to be found; however I don't think it's that important. I wrote about it here: Setting a Website for Your Business: Key Points (how to choose a web designer and do you need SEO?) (this is my post for the Talentbuzz blog contest.)
I think it's important not only to be found, but to manage your "brand" and what people can/will find about you. One suggestion would be to create a Google Alert with your name or your company's name to see when new info gets indexed.
When job hunting, it's also a good idea to be found on blogs (like this one), all the social networking sites; on LI, you can use a box.net app to include your resume;
Anywhere you can be digitally so when someone Google's you, you will show up in lots of places!
