Social Media Site that DoFollow

[JeffFerraro]

Hi everyone, I love this community and have a question:

I recently read the textbook Art of SEO which was written by some of the creators of this community.  In that book, there is a chapter on link building.  Within that chapter, they discuss social media sites and how to leverage them.

In that section, they refer to this article: http://www.searchenginepeople.com/blog/22-dofollow-social-media-sites-offering-profile-links.html. This article gives 22 social media sites that it says if you simply sign up, make a profile, and have your profile point to your web site, there will be a benefit because these sites profile sections DoFollow links.

My question is: Is there a tool that can tell me whether or not these 22 sites still DoFollow links?  Or at least if there profile section does pass link juice?  Any advise is greatly appreciated.

Sincerely,

Jeffrey Ferraro

Well, one way would be to look in the source code of the website. Find the profile link and see if there is a rel="nofollow" attribute in there. Or, get the SEOmoz toolbar and click the NoFollow finder, it will highlight nofollow links in pink, i believe.
