What is PageRank and How Can You Use PageRank in Your Link Building?
As Wikipedia has probably already told you that PageRank was named after Larry Page, the co-founder of Google. It may also have told you that it is a ranking scale that takes into account the amount of inbound links that a webpage has, as well as the amount of outbound links there are coming from the webpage. From this, a webpage’s PageRank is determined. The PageRank equation can be expressed as shown below:
This equation basically shows that when another webpage links back to the webpage in question (u), that page’s total PageRank is divided by the total number of outbound links on the page. This is then the amount of PageRank that is transferred over to page ‘u’ (often reffered to as ‘link juice’). The equation then gets the sum of all of the PageRank that is being transferred to page ‘u’ from the set of webpages that link to it (Bu). This then makes up the total PageRank for the webpage ‘u’.
Hopefully that hasn’t confused you too much because, in essence, it is a fairly simple idea, however; PageRank isn’t the ‘be all and end all’ of link building. Not only that but Google keeps these figures very closely hidden, so it is extremely hard to find out your exact PageRank. Google does, however, periodically post an inkling into what kind of PageRank a webpage as through the Google Toolbar PageRank (TBPR), which is ranked between 1 and 10 (10 being the best).
