Just as on you're CV you would have a Profile or whichever name you would choose to use for it, you're CV Website will also have one.
But as with everything on your CV website you can choose to just have the same information as you have on your paper CV or you can really go to town and give a potential employer plenty more information here.
If an employer is reading you CV website they are more likely to stay and read more details about you than they would normally get to say on your CV.
Giving you more chances to tell them about you and giving you more chances of securing that interview.
