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.
- HTTP GET request made to toolbarqueries.google.com from Google page ranking tool.
- Query string parameters in the HTTP request tells that, Page Ranking Tool has requested "Rank" feature for the page "http://rangahc.blogspot.in".
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 Rank_1:1:8Looking 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.
