dofollow is very good for getting pr but also nofollow link is also important it will get traffic to your website both links has own important
A link is a link - google sees it whether it is dofollow or nofollow. Nofollow links still get spidered by search engines and the anchor text is recognized and it gets added to the index BUT it does not have any link juice passed in that will affect PR. So, any link is valuable, do follow is more valuable though.
Hi If you go for do follow links Google will give value to those links and there is no value of no follow links for Google.
Hi . Both Do follow and no follow have the importance . but do follow is best . Do follow pass the value of you link to search engine spider .
