This guy and many others would disagree:
#1 with NHSEO aloneAll links can be useful and not all links are no-follow links. The main thing with any linking pattern is that the links are relevant, on a mix of domains and hosts, have a range of qualities with good ones mixed in and that are across all pages of your website. All of these things are taken care of by No Hands SEO.
Its true that generally dofollow links are better at helping with rankings but no natural linking pattern consists of a large percentage of dofollow links, it is a sure sign of sponsored links to game the results. The platforms supported within No Hands SEO are a mix of predominantly nofollow but ones such as NoFollow Free and CommentLuv are dofollow by default and the other platforms have a chance of being dofollow.
Obviously with every bunch of links you generate you will find lots of PR links also so there is a real mix of link types and qualities to create a natural looking linking pattern for a consistent growth.
