Recently I have been informed that the PageRank provided by pagerankstatus , a Firefox extension is different from official Google Toolbar. Since, I have been slightly involved with the development of this extension, I have studied the reason behind it. Example Target site: http://benmccann.com/ Pagerankstatus's PR: 4 Official Google Toolbar's PR: 0 Reason: Google's bug Analysis Pagerankstatus What pagerankstatus requests: ...features=Rank:FVN... What Google returns: Rank_1:1: 4 Official Google Toolbar (IE) What Google Toolbar requests: ...features=Rank:... What Google returns: Rank_1:1: 0 Official Google Toolbar (FF) What Google Toolbar requests: ...features=Rank... What Google returns: Rank_1:1: 0 Google info XML file : ...info:... PR inside XML file: 4 ( This might be the right PR. Same as of pagerankstatus. ) Conclusion (Google bug) Official Google Toolbar has downgraded the category/directory option; that's why now not sending "FVN" as "FVN"...
