How to Get Your Websites Google Page Rank Up

What is PageRank?
PageRank is a numeric value that represents how vital a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page’s importance from the votes cast for it. How important each vote is taken into account when a page’s PageRank is calculated.

PageRank is Google’s way of deciding a page’s importance. It matters because it is one of the factors that determine a page’s ranking in the search results. It isn’t the only factor that Google uses to rank pages, but it is an important one.

Below in further, we’ll occasionally refer to PageRank as “PR
How PR Calculated?
To calculate PR all inbound links are calculated and taken into account. These are the links which are coming from outside of our site.

 PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))

Above is the equation to calculate a page’s  PR. It is the original when PR was being developed.

In 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
We can simply see this as,

PR = 0.15 + 0.85 * (a "share" of the PR of every page that links to it)

share” = the linking page’s PR divided by the number of outbound links on the page.
A 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.

From 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.

If the PageRank value differences between PR1, PR2,…..PR10 were equal then that conclusion would hold up, but many people believe that the values between PR1 and PR10 (the maximum) are set on a logarithmic scale, and there is very good reason for believing it. Nobody outside Google knows for sure one way or the other, but the chances are high that the scale is logarithmic, or similar. If so, it means that it takes a lot more additional PageRank for a page to move up to the next PageRank level that it did to move up from the previous PageRank level. The result is that it reverses the previous conclusion, so that a link from a PR8 page that has lots of outbound links is worth more than a link from a PR4 page that has only a few outbound links.

Whichever scale Google uses, we can be sure of one thing. A link from another site increases our site’s PageRank. Just remember to avoid links from link farms.
