Backlinks and Pagerank

Many of us cares about pagerank and others do not care but get strong external links. There are sites has a PR 7 but is in the search engines? Become a PR websites only? I'll talk at length about this modest goal in this

explanation Thread :

Well known that the PR is very important, but some misunderstood, unfortunately, the PR person sized room for leadership positions, then comes to the position of SEO of the company .. Then he sleeps and depends only on its reputation as a director of the company will be the manager? Of course not, here for example there are sites PageRank PR 7, 8 maybe, but they do not see any trace of Google in terms of maintaining words or archiving progress here lies the reason for their addiction respect only of PR

The difference between Pagerank and Back-Link :

Pagerank is to get a page that you have Pagerank 1 to 10 and of interest here can return offers page and the words search engine, but requires you to work later to get the Pagerank not only based the Pagerank .. Back-Link is an external publication and here, it is sometimes better than PR because Google says the text (the list of search results to vote between sites) means that when your site over your competitors sites whenever I'm on the progress and maintenance of important words
And maybe double the PageRank 7 site and you just published outside.
