Google Optimization Tutorial: Steps to Increase Google PageRank

To Increase PageRank of your site it is recommended that you know these steps:

What is PageRank?

Google PageRank is a ranking system which ranks individual documents based on their empirical placement in the web. PageRank is the estimation that a random web surfer would cross a page.

When a page links to your page it is viewed as an independent vote of quality for your page by that person. Google is on a continual rolling update of the web, ranking the entire web in this manner. Many inbound links on are to home pages. The closer your page is to the home page (fewer links away), the more important that document must be to your web site.

If you have a great idea within your site it is possible that the page which that great idea is on will have greater link popularity (and thus more PageRank) than your home page.

How does PageRank work?

PageRank is passed through links. Each page only has so much PageRank which it can pass to other web documents. A dampening factor (approximately 85%) is set to allow the current pages PageRank to propagate through the rest of the web, while preventing all we pages from being ranked at a 10 or a 0.

The off going PageRank is split up between all links on that page (including links to other pages within that site). Therefore a PR 5 link on a page with 10 links is worth way more than a couple PR 5 link on a page with 100 links. One PR 8 link may be worth more than a thousand PR 3 links.

The value of any given link is hard to determine exactly. Generally though less links on a page means that more of that pages PageRank will be parsed out to your site. Also the higher the PageRank of a page the more PageRank it can pass on to other pages.

A page does not lose PageRank by linking out to other sites (unless it links out to penalized sites), it just has less PageRank to share amongst the other documents it is linking to.

What is the PageRank calculation?

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

PR= PageRank
d= dampening factor (~0.85)
c = number of links on the page
PR(T1)/C(T1) = PageRank of page 1 divided by the total number of links on page 1, (transferred PageRank)

In text: for any given page A the PageRank PR(A) is equal to the sum of the parsed partial PageRank given from each page pointing at it multiplied by the dampening factor plus one minus the dampening factor.

What scale does PageRank use?

PageRank uses a logarithmic scale. This means that it is harder to go form PR 6 to PR 7 than it is to go from PR 3 to PR 4. This is why there are tons of PR2, PR3, and PR4 sites, but few PR 8, PR 9, or PR 10 sites. Only a few sites have a PR 10.

Blogs and PageRank:

In addition blogs contain a ton of links interacting back and forth. Many argue that this is really destroying the PageRank system, but I disagree. Many of the top blogs are from book authors and other highly opinionated resources. These blogs are linked to a ton of times BECAUSE they have good information in them... that is the whole point of PageRank. In addition, blogs are rarely optimized for search engine rankings the way many other sites are...The usual goal of most blogs is just to express an opinion.

Get External Links

Get as many links as possible to your page.

Choose the pages having good PageRank. The PageRank of the site is different from the PageRank of the linking page.

For example: The PageRank of the site may be PR 6 but the PageRank of the linking page(ex. Links.html) will be PR 0. Ensure that your link is placed in a page with good PR.

Choose pages having minimum links possible (especially if their PageRank is very small). Because if a page with good PageRank has more than 50 links will dilute the share of the PageRank given to your link.

Check if the page where your link will be placed is well indexed by Google, otherwise its PageRank share for your page is worth zero and that will not bring anything to you. In particular, it should not contain any directive indicating to the crawlers not to index it (file robot.txt or META tags), and it should not be orphan page(page not linked anywhere in the site, as Google cannot index it).

It can be more effective to have a link from a page with PageRank 4 that contains only a few links than a link from a page with PageRank 6 which contains many links.

The two best examples of links to be obtained are those of directories DMOZ.org and Yahoo Directory who seem to play a great role in Google's algorithm.
