Job-Hunt is chock-full of great info and I especially like the Guide To Personal Branding.

There's a checklist to help you get started and helpful hints to keep you on track.

If you are job hunting and your online presence only consists of Facebook posts that you have to hide, I sincerely recommend reviewing the info on Job-Hunt:

A Gentle Reminder: your online presence will most likely be the first impression of you that an employer will get to see - make sure it is an accurate reflection of who you are and the value you bring.
