Do you have an awful lot of sites linking to you with the nofollow attribute appended to the link? Are you worried Google uses that as a signal to not trust your site? Google’s John Mueller said don’t worry, it won’t hurt you.

In a Google Webmaster Help thread, John Mueller of Google said having a lot of links with nofollows pointing to you won’t have a negative impact on your site.

It obviously won’t help you either but it shouldn’t hurt.

I am a bit surprised by this, because if 90% of the links pointing to my site were nofollowed, I’d think that would raise a red flag. Of course, assuming I had a substantial number of links.
