As we can see, there are some projects in the freelancer sites where the employer is asking for backlinks from a high pr site-and his condition is the backlink should be from that page which has the high pr, not from any inner page which has 0 pr. how it is possible? because most of the sites have high pr for the home page, not for all the inner pages. How can these guys do it?
although I thought someone here will ans my question-but still now I have not got any ans. But I have found a way. For a certain keyword, with SeoQuake software, pages can be found with page rank in search engine's result. then you can try to post a comment on that high page ranked page (if it is a blog or something like that).
