span style="font-weight: bold;"This is How PageRank is Calculatebrbr/spanTo calculate the PageRank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site.brbrPR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))brbrThat's the equation that calculates a page's PageRank. It's the original one that was published when PageRank was being developed, and it is probable that Google uses a variation of it but they aren't telling us what it is. It doesn't matter though, as this equation is good enough.brbrIn the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85. brbrWe can think of it in a simpler way:-brbra page's PageRank = 0.15 + 0.85 * (a "share" of the PageRank of every page that links to it) "share" = the linking page's PageRank divided by the number of outbound links on the page.brbrA page "votes" an amount of PageRank onto each page that it links to. The amount of PageRank that it has to vote with is a little less than its own PageRank value (its own value * 0.85). This value is shared equally between all the pages that it links to.brbrFrom this, we could conclude that a link from a page with PR4 and 5 outbound links is worth more than a link from a page with PR8 and 100 outbound links. The PageRank of a page that links to yours is important but the number of links on that page is also important. The more links there are on a page, the less PageRank value your page will receive from it.
