I was at SMX Advanced when Matt Cutts talked about it and he said that he accepted that SEO people will notice they (Google) did it (come on...) but since no one did, he talked about it. how ever, I wonder if Google keep ignoring from PR Sculpting. What do you think?
Amazing how they come up with these terms 'pr sculpting' 'link juice' etc - trade terms about SEO - I dont understand why people would add nofollow within their own sites (which is what PR sculpting basically is), you cant sculpt or control PR of whatever google assigns to it, its just simply take it or leave it kind of matter. Anyway PR algorithm is questionable because it assigns higher importance to other sites linking to a site, on the assumption that if others link to a site, then it must be better.That has given rise to all the blog networks where anyone with money can get many sites linking back to them.
I am not really familiar about that PR Sculpting, I have read one blog lately that talks about PR Sculpting and I regret for ignoring that.
