Do reciprocal links have a negative effect? Even if they are "no follow" and relevant? What consequences does this have on PageRank?
I thought that having a mixture of "do follow" and "no follow" links was good for creating a natural looking link profile?
The only negative point is if they are no follow since they can't be indexed. Hence won't benefit in search engine ranking.
I think nofollow is completely different to noindex. Just because a link is nofollow doesn't mean it won't be indexed.
No follow or Do follow, a backlink is a backlink, go get it in my opinion, it cannot harm you in any way, even if it cannot help, and if it is available in the exact same niche as yours even a no follow backlink can help
I have some thing to share an expert advice on no-follow and do-follow linking Matt Cutts of Google has provided advice about PageRank and the no-follow attribute. If you are considering changing your links from no-follow to do-follow, please check the video below to be helpful. http://www.youtube.com/watch?v=NQfOhncTXRU&feature=player_embedded
