PageRank is Googles way of determining a sites worth based on the number of incoming links it is. Fundamentally, Google counts the number of links pointing to the site & interprets it as confidence votes. Fundamentally put, the more votes for a site, the worthier the site is in the eyes of Google.
Net site Rating
Everything appeared to work out fine until site owners & site owners realized the potential of embedding industry specific keyword phrases in their Meta tags & other site codes to manipulate higher rankings in search results. Search engines started getting cluttered with sites that spammed their content with the abuse of relevant keywords. Most had the keywords but had poor content. The credibility & relevance of search engines were being challenged so they had to think of a way to offer a more refined output to users.
In the work of the years that the net was emerging, numerous sites that have industry-specific content were continuously being added to the net every day. Web surfers or searchers had only a few tools to locate these sites which they knew existed but had no idea on how they can be accessed. The birth of Yahoo provided some relief as it organized its listing listing by classifying each site it discovered & likewise embedded a search engine in its site. This started the use of keywords existing in the database for site searching. Other search engines did likewise with the search trend & relied heavily on Meta tags to classify the relevance of an online site based on keywords present in the tags.
The Google founders, Sergey Brin & Larry Page took this logic further when they formulated a search engine algorithm that shifted the rating weight to off-page factors. They came up with a formula called the PageRank where the algorithm would count the number of sites that link to a page & assign it an importance score on a scale of 1-10. The Google scale is not linear but exponential in nature.
Google saw the issue which conventional search engines had to face in this situation. It recognized the fact that as long as the control of relevance remained with site owners, the rating results would continue to be contaminated with the presence of high rating sites that artificially inflate their keyword relevance. By the nature of the net, it is accepted that the net is based on hyperlinks where a site is largely measured by its linkage to prominent sites & the number of links it is. There is the assumption that a site is lovely & important if more sites link to it.
The PageRank algorithm which was named after its founder, Larry Page, was deployed with the launch of Google in 1998. The successful result enabled Google to surpass its competition due to the superior & relevant results it could serve using their formula that was difficult to manipulate. The new algorithm helped in providing authentic & quality information while presenting a challenge to site owners & site owners who cheat their way to top rank. Googles PageRank is thought about one of the primary off-page factors that influence a pages rating in the search engine result pages. The PageRank value of any page can be checked by downloading the Google Toolbar.
Googles PageRank
PageRank is explained by Google in the following manner:
PageRank depends on the uniquely democratic nature of the net by using its large link structure as an indicator of an individual page value. In essence, Google interprets a link from page A to page B as a vote by page A for page B. But Google looks at over the sheer volume of votes or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves important weigh more heavily & help to make other pages important. Important, high-quality sites receive a higher PageRank which Google remembers each time it conducts a search. Of work, important pages mean nothing to you in the event that they dont match your query. So Google combines PageRank with sophisticated text-matching techniques to find pages that are both important & relevant to your search. Google goes far beyond the number of times a term appears on a page & examines all aspects of the pages content (& the content of the pages linking to it) to pick if its a pleasant match for your query.
The Google Toolbar is downloaded free & can be installed in the users Net Explorer within minutes. It facilitates the display of the PageRank of each web page visited on a scale of 1-10. It does not display the PageRank of web pages that it is not indexed. The PageRank displayed by the Toolbar refers to individual pages & not to the site as a whole.
The exact algorithm of each search engine is a confidential matter. However, search engine analysts think that rating is a product of a combination of page relevance & PageRank. The search results of Google search are admittedly high in terms of relevance. This is largely responsible for the resounding success it is experiencing. Other major search engines have adapted this logic in some form with variations on the assigned importance of this value.
A webpage that links to one site passes a portion of its own PageRank value in the technique. The higher the PageRank of the linking page, the higher the worth passed. PageRank is divided over the total outgoing links of the linking page. In essence, a link from a PR10 webpage with 20 outgoing links represents more value than a link with a page of the same PageRank that has 100 outgoing links. Pursuing links from higher PR web pages with lesser number of total outgoing links ought to be prioritized.
Most search engines place significant importance on link popularity in evaluating the importance of web pages rating & indexing purposes. The method of Link Popularity is based on the number & quality of links connected to an online site page. This is used together with the quality of sites that are linked to the net site, the quality of content & the industry relevance to the site.
One of the more critical aspects of search engine promotion is the building of link popularity. The alteration of PageRank is neither simple nor recommended but PageRank can be enhanced by improving link popularity. A long term link building campaign ought to be undertaken to boost a sites PageRank & consequently accomplish a significant improvement in site rating. Off-page factors continue to gain importance in rating sites thus it is become necessary to actively boost such factors to favor the net site. Exchanging links with sites falling under the same industry segment has become more open as site owners finally recognize the importance of link popularity & PageRank.
