About a year ago there were those who held the idea that accumulate the highest number of links to your own web page made up the Page Rank. From a logical stand point, not a bad idea considering that the Page Rank in short, is nothing but a popularity rating. If our site gets many links means it's very popular .... Right?

This proposal was not without foundation and it is true that Google is fairly supported this conclusion, so that webmasters began to realize that spamming, for thousands of sites became more popular your website, not only for users outside the advertised content, but Google itself, which felt deceived by these techniques greatly expanded to popular sites that did germinate links and more links for hundreds of public forums.
After several updates Google reacted. And it is quite absurd to think that you can fool par excellence who defines the game, simply because what happens is that the end of each item is put new rules.
Google takes action and then determines what I call particularly the 'quality of links'. If you look or use the Google webmaster tools http://www.google.com/webmasters can see how many links there to our website.

Why?

Well the answer is simple. Not all the links on our site prove to be quality links to google and relevant to our site. When Google crawls the content of Web pages, ranks pages by their content, and is able to draw thematic relations. It would be very suspicious link from a website that offers sunglasses, as a web 100seotips because ... .. What the link brings the user looking for sunglasses?

Will this mean that the link is not relevant? Well actually it is. These links have no weight in the calculation of our Page Rank, they are simply discarded, but be careful, that does not mean that from that page of sunglasses, we can recover traffic. This does not mean that the link is useless, of course if it is, if the goal is to raise our Page Rank.

Most of the time I have observed people talking about 200 parameters that get calculated in increasing PR.  With the kind of website i have optimized, I have sorted out few things which helped me improving my PR which are as below.

Age of the website

Quality of traffic and geo location.

Regular updates in the content of the website.

Quantity of the web pages with unique quality content.

Quantity and quality of back links

Its a complete algorithm of Google which is too difficult to understand. Actually, the fact is, Google look for many factors while assigning the page rank to any site. Consequently, its really a tough task measuring what are the points responsible for the page rank.

One of the factors could be the amount of dofollow links, quantity, quality and page rank of your back-links.

It is very big calculation so many things are taken into consideration and it also takes much time to update.
