PageRank is a numeric value representing a page’s importance. PageRank is essential as one of the items factored into deciding where a page comes up in search results. Though it’s not the only factor, it is definitely an important one. A PageRank results from a ‘ballot’ cast among all the other pages on the World Wide Web about how important a page is. It is used by Google to determine a page’s importance and relevance. Google interprets a hyperlink as a vote of support for the page that was linked to. But, it also analyze the page rank of the page that so to speak , voted, or in our case, that linked itself to the first page. Being linked by a page with a high PageRank, gives a page higher rank and importance than a link done by a page with a low PageRank. Understandably, if there are no links to a web page there is no support for that page. Google assigns a page rank based on a probability value on a logarithmic scale, similar to the Richter scale. Other factors that influence a site’s page rank include the relevance of search words on the page and amount of viewers who visit the pages. Adding more inbound links is another way to increase PageRank.
Additionally, as the number of pages in a site increases, so does the maximum amount of PageRank in a site. Although adding new pages does increase the total PageRank within the site, some of the site’s pages themselves, will lose PageRank as a result . The solution is to link the new pages in such a way within the site that the important pages don’t lose out, or to acquire some more inbound links. Beware though, of adding similar or identical pages to a site, just to increase the page number, because it can alert Google to penalize those pages or even the whole site.
To calculate the PageRank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site.
In simple terms, a page’s PageRank = .15+ .85*. . .85* is the value of your own page. Then a page can ‘vote’ an amount of PageRank onto each page it links itself to. It can vote any amount up until its own rank. This value is shared equally between all the pages that it links to. We see too that the amount of links on a page is taken into account in such that the more links there are on a page, the less PageRank your page gets from it.
Outbound links may leak out PageRank. When linking to other site, try to make sure that there is enough inbound linking occurring to make up for it.
In addition, it is wise not to link out to sites that may be penalized sites. For example a site that has PageRank O is usually a penalty and it’s better to stay away.
Whichever scale Google is using to, one thing is for sure, links from other sites increase our site’s PageRank, as long as they aren’t from link farms. In addition, voting on another’s PageRank doesn’t in any way take away from our own.
