Page Rank

The Page Rank of a web page is very significant to get high position in the serps. The term page rank is offered by the big G (Google). Yahoo also offers such a term called web rank. The Page Rank of web page can be calculated using the Page Rank algorithm. The algorithm says that the page rank of a web page is the sum of the Page Ranks of all web pages linking to it (its inbound links), divided by the number of links on each of those web pages (its outbound links).

Mathematically the Page Rank algorithm can be represented as follows:
PR(WP) = (1-d) + d [ PR(W1) / O(W1) + ... + PR(Wn) / O(Wn) ]
where PR(WP) is the Page Rank of a web page WP
PR(W1) is the Page Rank of a page W1
O(T1) is the number of outbound links from the web page W1
n is the number of sites that link to webpage WP
d is damping factor in the range 0 < d < 1, usually set to value 0.85
Thus from the above algorithm it can be concluded that there are two factors that can affect the Page Rank of a web page.

• The number of incoming links/inbound links to the web page.
• The number of outgoing links/out bound links on the page which points at your page.

The more number of inbound links is better as it helps in increasing the Page Rank. The fewer of outbound links on the page which points at your page is better.

Page Rank is also some way related to link popularity. Link popularity is the quality and quantity of inbound links to a website. So the calculation of link popularity depends on the quality and strength of the links, not just on the quantity and volume of links. So, you should be very careful while building and increasing the number of inbound links to your site as it shows its direct affect on the Page Rank of the web page.

As some people have in their mind that increasing the Page Rank of a web page is too difficult, but it is not so. Before you begin to increase the Page Rank of your website and site?s individual web pages, you need to evaluate the current Page Rank of your site's pages.

Internal Linking

Another factor that plays an important role in the Page Rank of the pages within a site is Internal linking. It is most common that the homepage of a site has the highest PR of the website. The Internal linking (the links that exists among the home page and the other pages of the site) does not help in increasing Page Rank of a web page, but sharing the Page Rank of the site, and the intensity of your keyword strength and theme.

You should follow the points for internal linking in your site.

• Be sure that the home page of your website (index.htm page) is linked to all secondary pages within the site.
• Be sure that the secondary pages (pages linked to the home page) of your site are link to each other.
• The secondary pages should link to the third level pages (pages that link to the secondary pages) within their level.
• The third level pages should link to each other within their level.
• The third level pages should link back to the secondary pages from where they are linked from.
• The links between the third level pages should not be very complicated and heavy.
• Links between the inner pages, regardless of their level is necessary.
• All the pages should be linked regardless of level, where the text on the page is keyword specific.
• If fourth level pages are also present the same linking structure should be followed that has been specified for the second and third level structure.
• Link should be created among pages that is relevant to each other.
• Only keyword specific link text / anchor text should be used for linking between pages.
• Standard HREFs should be used in links for easy search by search engine spiders.

External Linking

The most significant factor in determining Page rank is external linking. External links are the incoming links that send traffic to your site. Attempt to increase Page rank can be made by contacting other websites to provide you a link back. The websites to whom link request are sent should be relevant and on theme (same theme).
