To know the position in top 1000 results of google

I got impressed by a tool named http://seoserp.com/ which tells the exact position of the website in the top 1000 results of the Google. simply we need to enter the site name and for the keyword we want to check the position in Google.

There is also an option available to check the Top 100 results in google.I hope this tool will be very helpful for my readers.
