`GOOGLE PAGERANK ALGORITHM EXPLAINED
`
`What is PageRank?
`
`PageRank is Google's measure of importance assigned to a web page on a scale of 1 to 10. You can check the PageRank value
`fhttp://www.evancannichael.com/Worbheets/5-Charae-More-$.ohpl of any page by downloading the GoogleToolbar.
`This article is intended at understanding PageRank and providing an insight into its different aspects.
`
`History of Site Ranking
`
`In the early 1990's when the web was emerging, several sites having industry specific content were being added to the web each day. Web
`surfers, on the other hand, had very few tools to locate such sites, which they believed were out there but did not have a clue about their
`domain names or web addresses. With the birth of Yahoo in 1993 , surfers were offered some relief. Yahoo classified each site it discovered
`in a neatly organized directory list and also embedded a search engine in its site to search for sites based on 'keywords' existing in its
`database. Several other search engines like AltaVista, Excite, Lycos etc. followed the search trends offering site search facilities to users.
`Most of these search engines relied heavily on Meta Tags to classify the relevance of websites based on the keywords they found in the
`tags.
`
`Things seemed to work out fine before site owners and webmasters realized the value of how they can 'embed' industry specific keyword
`phrases in their Meta Tags and other site code, thus manipulating their way to show up higher in search results. Over a period of time,
`search engine results started getting cluttered with sites that spammed their content with relevant keywords but had poor site content for
`the visitor. The very essence, credibility and importance of search engines was now being challenged to deal with how they could offer a
`more refined search output to their users.

`

`Google realized the problem conventional search engines faced in dealing with this situation. If the control of relevance remained with the
`webmasters, the ranking results would remain contaminated with sites artificially inflating their keyword relevance. Web, by its very nature is
`based on hyperlinks, where sites link to other prominent sites. If you take the logic that you would tend to link to sites that you consider
`important, in essence, you are casting a vote in favor of the sites that you link to. When hundreds or thousands of sites link to a site, it is
`logical to assume that such a site would be good and important.
`
`Taking this logic further the Google founders, Sergey Brin and Larry Page formulated a Search Engine algorithm that shifted the ranking
`weight to off-page factors. They evolved a formula called PageRank (named after its founder Larry Page) where the algorithm would count
`the number of sites that link to a page and assign it an importance score on a scale of 1-10. More the number of sites that link to a page,
`higher its PageRank.
`
`Note: The scale of 1-10 on Google is not linear. It is exponential in nature, believed to be a
`base of 6 to 7, that is, PR 7 website
` (http://www.evancarmichael.com/Worksheets/16-Build-A-Lead-Generating-Website.php) is 6
`times more important than PR 6 website.
`
`Sergey Brin and Larry Page deployed their PageRank algorithm with the launch
` (http://www.evancarmichael.com/Worksheets/10-
`Launch-With-No-Money.php) of Google in 1998 . The result was a grand success. Google surpassed its competition by serving superior
`and relevant results using a formula that was difficult to manipulate. This new algorithm not only helped in providing authentic and quality
`information, but also made it very difficult for site owners and webmasters to cheat their way to a top rank.
`
`Google's PageRank is important because it is one of the primary off-page factors that influences your page's ranking in the search engine
`result pages.
`
`PageRank in Google's own Words
`
`Google explains PageRank as follows (http://www.google.com/technology/): PageRank relies on the uniquely democratic nature of the web
`by using its vast link structure as an indicator of an individual page's 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 more than 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 and help to make other pages "important."

`Important,
`(http://www.evancarmichael.com/Worksheets/#Section3) it conducts a search. Of course, important pages mean nothing to you if they
`don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important
`and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's
`content (and the content of the pages linking to it) to determine if it's a good match for your query.

`
`Relationship between Search Engine Ranking and PageRank
`
`While the exact algorithm of each search engine is a closely guarded secret, search engine analysts believe that the search engine results
`(ranking) is some form of a multiplier factor of 'Page Relevance'and 'PageRank' . Simply put, the formula would look something like -
`
`Ranking = (Page Relevance) x (PageRank)
`
`The PageRank logic made sense and the algorithm seemed impregnable at the hands of the webmasters. The search results of Google
`search have demonstrated high relevance and this is one of the main reasons for their resounding success. Most other major search
`
`

`

`engines have adopted this logic in their own algorithms in some form or the other, varying the importance they assign to this value in
`ranking sites in their search engine result pages.
`
`Since the early days of the web, search engines have constantly tried to evolve better algorithms to rank relevant web pages. Most search
`engines give significant importance to "link popularity" as a criterion for evaluating importance of web pages ranking and indexing
`purposes.
`
`The Google Toolbar
`
`You can download Google Toolbar (free) and install it in your Internet Explorer within minutes. Amongst other useful features, it displays the
`PageRank of each web page you visit. The Google toolbar appears just below your Internet Explorer browser and can be used for making a
`search on the web from any page. Google toolbar displays the PageRank of each web page on a scale of 1-10. If you have the Google
`toolbar installed in your browser, you would be used to seeing each page's PageRank as you browse the web. Google does not display the
`PageRank of web pages that it has not indexed. Please note that the Toolbar displays the PageRank of individual pages and not the site as
`a whole.
`
`Note: Ideally, a higher PR value means you can expect to take on (or expect to beat) more
`competition (number of existing web pages) for that search term to land a good ranking position.
`Therefore, we recommend making PR based selection of your keyword phrases.
`
`What is Link Popularity?
`
`"Link Popularity" system is based on the number and quality of links you get to your web site pages. This means, higher the number of links
`pointing to your page, the more important your page would be considered. The 'numbers' on stand-alone basis are not the only factor that
`determines your site's importance. The other related factors that determine your site's importance are the quality of sites that are linked to
`yours, quality of their content as well as their industry relevance to your site. A web page that links to your site passes on a portion of its own
`PageRank value to your site. The higher the PageRank of the linking page, the higher is the value passed on to your page.
`
`PageRank also gets divided over the total outgoing links of the linking page. For instance, you get a higher value from a link on PR5 web
`page that has only 15 outgoing links as against, from a PR5 web page that has 100 outgoing links.
`
`It is therefore important to pursue securing links from higher PR web pages that have lesser number of total outgoing links.
`
`Link Popularity Check
`
`There are simple ways you can use to check the link popularity of your web site. The simplest way is to type the following in Google Search.
`link:www.yoursite.com
`
`Other major search engines have different syntax to search for your link popularity. You can use the Link Popularity Analyzer tool on our site
`to check the link popularity of your site across various search engines in one shot.
`
`Building Link Popularity to Increase PageRank
`
`Building Link Popularity is one of the most critical aspects of search engine marketing. While manipulation of PageRank is not easy, it is not
`difficult to enhance it by improving your link popularity. By undertaking a long-term link building campaign, you can boost your site's
`PageRank and improve your site ranking significantly.
`
`In the recent past, Google and other Search Engines have deployed other components of algorithm similar to PageRank (like TSPR- Topic
`Sensitive PageRank and Hilltop- Links from expert documents ) and further, taken the ranking weight to off-page factors.
`
`As the off-page factors gain importance in ranking websites; it has become increasingly important to pro-actively boost such factors in your
`favor. As more and more webmasters now realize the importance of PageRank and Link Popularity, it is not difficult to exchange links with
`sites that fall in your industry segment.
