How to build Backlinks from Linkedin.com?

As you know,linkedin.com's PR is 9!
Therefore,we will benefit a lot if we manage to build Backlinks from it.
I have put my site's URL in my profile and post my site's URL in the "SHARE".
But there is still no backlinks from linkedin.com.
Can someone be kind enough to tell me how to build backlinks from Linkedin.com?
Highly appreciated!

I am pretty sure the linked backlinks are no follow... so don't bother.

Linkedin is social media site.They use a redirect... you don't get a backlinks directly from linkedin... it may help you to get traffic for your site....

So it is not really intended to get backlinks? What is it when you say redirect?

Add your website in your profile. Share some useful content which link to your website...
