hello dp i want to ask some blog comment is making it no follow if comment in such blogs helpful for pagerank or it backlinks or it is nothing do as it make nofollow as i see some sites have backlinks in yahoo my be 2000 and i cheek it it come all from blog comments for no follow and when i cheek in google i found 0 backlinks for these site wating ur opinion and advise
Nofollow backlinks helps to increase traffic but nofollow is considered by yahoo if it is valuable and get nice rank on yahoo.
Today, algorithm is changed, we need natural links today, in the natural links, there would be combination of all, dofollow, nofollow, relevant niches, irrelevant niches, directory links, article links etc.....
Wow it's my 1st time to hear about Natural Links. You have good points about it Alex. In my blog i sometimes give dofollow links to other blogs, also nofollow.
In dofollow blog our back link will be increased. But in nofollow blog only the traffic will be increased.
there are some blog site that has a do follow comment that is why blog commenting have become helpful in getting better serp rankings.
Back links either do follow or no follow are good and they tend to increase page rank. But its good to prefer do follow links.
