If someone is offering you, 3000+ Signature links for $15/month and other is offering you, PR3 link for $15/month Where would you like to invest?
It depends on your niche. For example. It would be a great offer if you were a web related business and got 3k sig links in Digitalpoint , not only for SERPS but also for the webmasters that would click the link from the forum. Also the PR3 would need to be relevant... Whats your niche?
I guess it depends on the age of the site and its niche, as the sig links could harm it more if it is established.
Actually I am asking from sellers point of view. I have a PR3 site and my sig links are increasing so I was wondering if I make the above mentioned offer for the same price, where will people pay more attention/interest? If webmaster pay more attention to PageRank then I will concentrate more on my site and will try to increase its pagerank, but if they care more about sig links then when I reach 3000 posts I will start selling it.
Depends on the buyer. Sig don't give much PR but can give a few places in the Serps. Links probably can give both.
