Profile Link Building

In my own opinion, making backlinks from profiles, can't help you a lot. If you want that it helps you, you should participate on the forums you have signed up to them. Only by joining forums and making a profile and leaving it, you will not get a good result from it.

 

it is dofollow linkbuilding,mainly of creating a webpage

 

You have to make sure they are do follow links though

 

Web 2.0 are the social networks like Twitter and Facebook, the link building techniques are no different from having your site in the profile
