I hear you ask What makes a PR (Google’s PageRank) domain so special?

Well let me answer your question.

Assuming the PR of the domain is genuine and not fake then it tells you a lot about it. To gain PR sites must provide quality links to that domain, thus the PR is passed down to the linked domain/page.

Also when a site has a quality link people tend to visit it and check its content out, which in return generates traffic and also gets spidered by google more often.

Traffic is an important aspect if you are after a good website especially if you are after generating income using PPC networks such as google’s AdWords, Clicksor etc..

Bing spidered by google often means that you are likely to gain a higher position in google’s search results which goes back to generating more organic

traffic.

Also it helps towards improving your SERP (search engine results page) because the more people viewing a certain web-page for certain keywords the more likely it will show up in your pages SERP.

So I hope I managed to inform you why Google’s PageRank is important. Not the most important but plays a role in a good website.
