Hi,

I have used keyword suggestion tool to analyze the competition of one specific keyword,

In Google Adwords Keyword Tool, It showed the Monthly search of around 3,68,000

In Seobook Keyword Tool - It showed the Monthly search for Google as 61,380.

Which data I should take it as the correct value to do my keyword research.

Please suggest any accurate tool to do keyword research.

Thanks
