How Google toolbar gets page ranking

Google Page Ranking is very helpful to know how Google has rated your page. If rating is around 4 to 7, it's good. Your page will appear in top of the search results. If your page is not yet ranked by Google or the ranking is the range of 1 to 3, you can alter edit page of the page and more importantly the structure of it, so that your page become SEO friendly and earns good ranking with Search Engines.
In a previous post explained on how to enable the Google PageRank button for IE browser. In this post let's learn more on how does the PageRanking button get's the page rank from the Google servers. Sounds interesting! Read on.
Yesterday I was interested in knowing how does Google page ranking button get's the page ranking for a page.

Here are the findings on how Google toolbar gets page rank:

  • Started the Fiddler.
  • Started the IE browser and browsed rangahc.blogspot.com.
  • Looked at the Web session in the fiddler. Selected the request to toolbarqueries.google.com and went to Fiddler composer. Google Page Ranking Request in Fiddler
    Observation below:
    1. HTTP GET request made to toolbarqueries.google.com from Google page ranking tool.
    2. Query string parameters in the HTTP request tells that, Page Ranking Tool has requested "Rank" feature for the page "http://rangahc.blogspot.in".
    3. Later looked the response for HTTP request. Selected the HTTP request and went to Response raw view.

      HTTP/1.1 200 OK
      Date: Sat, 16 Mar 2013 07:51:26 GMT
      Pragma: no-cache
      Expires: Fri, 01 Jan 1990 00:00:00 GMT
      Cache-Control: no-cache, must-revalidate
      Content-Type: text/html; charset=UTF-8
      Server: gws
      X-XSS-Protection: 1; mode=block
      X-Frame-Options: SAMEORIGIN
      Content-Length: 11

      Looking at the HTTP Response we can say that page rank for the page is 8.
      Note: http://rangahc.blogspot.com is not yet got any ranking. The response is for some other site.

That's about how the Google Page Rank button in the Google Toolbar get's the page ranking and displays to the user
