We usually set d to 0. 85. There are more details about d in the next section. Also C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows: PR(A) = (1-d) + d (PR(T1)/C(T1) + . . . + PR(Tn)/C(Tn))
Note that the PageRanks form a probability distribution over web pages, so the sum of all web pages' PageRanks will be one.
The Anatomy of a Large-Scale Hypertextual Web Search Engine (Sergey Brin and Lawrence Page, founders of Google)
To conform to the PageRank algorithm follow these steps:
1. Get inbound links to your website
Google ranks your pages according to the number of links pointing at your page. Try to get as many links pointing at your pages as possible.
2. Your Title Tag
The title of your page is important. Place a descriptive title to you HTML tags in the section of your web page. Do not leave it with a title like "New Page", or “untitled”.
3. Content-Laden Pages (Keyword Density)
Use more of your keyword on your pages. Be focused on your content. It has often been observed that Google considers keyword density a large factor in ranking pages in search engine results, more so than many other search engines.
4. Keyword-laden Links?
Insert more description on links to your website. For example, a link with the text "Cheap Medical Store" pointing at your site will cause your site to be listed earlier if a visitor searches for "cheap medical store" than if the link simply said "click here".
5. ALT tags on Images
Place description on images. Add ALT tags to achieve this on images. Google indexes the text given in the ALT tags of images.
6. Use the Google Toolbar
The Google Toolbar is an ActiveX control that installs into IE, and shows the Page Rank of any page that you visit. The toolbar can be obtained from http://toolbar. google.com/. If you use Internet Explorer, you can get an idea of what Google thinks of how important your site is in general, by downloading the Google Toolbar.
