Even if an article is submitted to a high PR site, the page rank of the specific page where the article is found is zero. How do we increase the PR of that specific page? Thanks.
page rank goes by individual page. being on an authority site helps. however many other factors involved as per PR of a page. You could try building links for that specific page.
Its true PR will be monitor by individual and make sure the article will be post on do follow article directory.
Actually I don't think one back link from a high PR site would do much to increase the page rank of any specific page. Otherwise anyone owns a Facebook (PR 9) account can easily build back links on it and gain high rank for their own website. I mean, you need more back links from different high PR sites. Just keep on writing and submitting good quality articles to build back link from high PR site.
