@deepakgFeb 21.2012 — #You can use Google alerts if you have any query to be solved but instead of using Google alerts for checking keyword rank, I would personally suggest you to do a manual analyses of keywords.
@iPhoneappsFeb 21.2012 — #Yea, very well said.. The keyword's ranking should be checked manually as it will give you correct results.. On the other hand Google alerts will help you best in solving queries..
