Hello, I wonder something about pr linking. For example someone sell a link on the high PR site. But this site only contains "high pr" "gain your pr" etc.. seo words. Now i think google can determine who sale link for pr and you know google dont likes it. I think google only loves natural linking by the way google can be ignore a link on the "for high Pr link pages" If you share your ideas will be much appreciated.
It's widely known that Google does not approve of link buying. The big questions is 'can they detect it?'. Many people believe that Google could never detect a purchased link, but as you say if certain keywords appear on a page then maybe Google will devalue the links form it? Although I believe that Google could detect it, I think that at the moment Google are just voicing their disapproval at purchased links. Personally I wouldn't buy a link on a site with those sort of keywords anyway.
