Backlinks to site.com (without www)

[bele]

I have a website with 301 redirection from site.com to www.site.com. And we have built many backlinks to site.com (without www). Are these backlinks still give us juicy?

yes, 90% or so of PR is passed when doing a 301 redirect. Try to get links to your site to be www from now on and if you are using a trailing slash (.com/) for example as your representative homepage URL it would be better to have that in the links pointing to your homepage as well.

Yes, those links will still pass most of the juice. Matt Cutts has said in one of his videos that doing a 301 redirect passes almost all of the link juice, a very tiny bit is lost, which is not a concern. No need to worry
