Google Page Rank (PR) – Actual Vs Toolbar
Anyone who has trolled the various search engine optimization (SEO) forums on the web will know that Google Page Rank (PR) is often a topic of discussion Buy Google Reviews. There are a lot of misconceptions floating around out there regarding PR. The following should clear up some of them.
Page Rank is Google’s patented method of measuring link popularity for a given URL. By link popularity most people mean the number of times a URL is cited or linked to by other URLs on the web. But in Google’s case, link popularity measures not only the quantity of inbound links but also the quality of inbound links. A citation or link from page A to page B is seen by Google as a “vote” cast by page A in favor of page B.
A lot of the confusion around the topic of Page Rank stems from the fact that there are two kinds of PR that Google associates with URLs. One is the “actual” PR for the URL, and the other is the Google toolbar PR for the URL. These two types of Google Page Rank are very different.
The “actual” Page Rank of a URL is one of the 200+ ranking factors used by Google to rank a URL in the SERPs. It is this “actual” PR that has existed since the beginning of Google and that is important to search engine optimization. The formula for “actual” PR was first discussed in section 2.1 of The Anatomy of a Large-Scale Hypertextual Web Search Engine – a paper written by Sergey Brin and Larry Page while at Stanford which became the blueprint for what we now know as Google.
Every new URL starts out with a minuscule amount of Page Rank. As other pages link to that URL, it is passed some amount of PR from the page that links to it. How much PR is passed basically depends on the amount of PR the page linking to it has accumulated and how many outbound links exist on that page. As more and more pages link to the URL, it accumulates more and more PR.
