    Toolbar Page RankVs Real Page Rank:Real Page Rank Ranges from  0.15 to billions
  • 16.
    Toolbar Page RankRanges from  0 to 10
  • 17.
    Reason:- In orderto avoid using a very long number to represent the PageRank of web pages, therefore Google has divided the Total PageRank into 10 ranges or 10 scales. This is called Google Toolbar PageRankReal PR values are what Google actually uses in their algorithm, and these values are constantly changing.
  • 18.
    Toolbar PR valuesare only updated every 3 - 4 months
  • 19.
    When a pageis created, PR from 0-1 can be easily acquired. However to raise the PR from 6 to 7 it is required by significantly more inbound linksPAGE RANK CALCULATION:

    Initial PR fora page is 0.15Page Ranking Behavior:Fig (1) Fig(2)Fig -1, Web pages which are well-linked, meaning every page has at least one inbound link and one outbound link. This allows the PageRank to "flow" through all the pages and achieve the maximum total Page Rank.
  • 23.
    Fig-2, Webpages contains a dangling link, meaning it links to a page that doesn't link out to anything. A dangling link prevents the system from achieving its maximum total Page Rank because it stops the flow of Page Rank. Dangling Link (dead-end)

    Add links tothe important pages:However, most websites have several important pages that deserve high rankings for relevant terms--not just the home page.
  • 25.
    Page Rank valueof a single page can be increased by adding more links to it.
  • 26.
    A page accumulatesPage Rank from its inbound links and distributes Page Rank evenly across its outbound links.Subtract links from unimportant pages:Google wants to rank pages that are independently valuable to Google's users. In other words, when a user types in a query, they are searching for something specific and Google wants to satisfy that user after one click.
  • 27.
    If the importantpage is reached only after too many clicks the PR will be relatively lowered.For example, if a user searches for iphone, Google wants to deliver Apple's page about iphones--not the Apple home page or their sitemap or any other page that would require the user to click unnecessarily.Hierarchical structure:The more pages you have on your site, the higher the maximum total Page Rank. When we talk about "adding a page," it is assumed that the new page will be valuable and index able, according to Google.Page rank sculpting:To redistribute PageRank to important pages, a process called PageRank sculpting.
  • 28.
    The goal ofPageRank sculpting is to increase our current search engine rankings by simply altering the crawlable linking structure of our site.rel=“nofollow”Distributes PageRank:<a href="http://www.seomoz.org">SEOmoz</a>Does NOT distribute PageRank:<a href="http://www.seomoz.org" rel="nofollow">SEOmoz</a>

    Indexing - Processwhere Google "reads" the content of your webpage and transforms it into a representation of content and processed for search results.
  • 34.
    The process ofindexing a webpage includes things like removing HTML code, determining keyword frequencies and assigning weighted values to certain terms (depending on how the terms appeared in the content).
  • 35.
    If you includethe noindex attribute in your page's robots Meta tag, you are basically telling Google not to consider that page relevant to any query, and therefore, not to list it in any search results.Crawling - Process of a search engine identifying links in your content and recording them.
  • 36.
    Google uses thisinformation to discover new pages and to calculate PageRank.
  • 37.
    Adding the nofollowattribute to the robots Meta tag will tell Google to ignore all the links on the page.
  • 38.
    Caching- Google storesa local copy of your page on its own computers.
  • 39.
    This copy isessentially a snapshot of your page's code
  • 40.
    Webmasters whodon't want Google to cache their page can add the noarchiveattribute to the robots Meta tag. THANK YOUSubmitted BySudhahttp://sudhaseo.blogspot.com
