How is PageRank Calculated?

　　The full PageRank algorithm was created by Larry Page at Stanford and is as follows:

　　PR = 0.15 + 0.85 ( PR(Backlink 1)/TotalLinks(Backlink 1) + PR(Backlink 2)/TotalLinks(Backlink 2) + … + PR(Backlink X)/TotalLinks(Backlink X) )

　　Recent rumours have circulated in the industry that PageRank could well disappear over time, with websites potentially having their last PageRank sticking to them for life. For high PageRank sites this would be welcomed, but for low ranking PR sites this could only be negative. If the rumours prove to be true, in time PageRank could just be removed and not be visible at all. This is another potential option Google could utilise if they so wish.

　　Many SEO companies and webmasters focus on PageRank as an indication of success, however PageRank cannot and should not be forced – the process should be a natural indication of the authority your webpage has built through your efforts to attract targeted visitors.

　　We have seen many low PageRank sites that have very good SERP rankings, hence proving PageRank does not mean high rankings. However, the longer term strategy of a webmaster or site owner is to build authority and rankings for overall stabilised success, this can be achieved through natural methods of search engine optimisation to attract visitors to your target webpage.
