Plz any one can tell me what is the "Global Monthly Search Volume" in google Adword tool. As a example my key word is "weight loss". when i search that key word in Adword tool it shows "Global Monthly Search Volume" is 11,100,000. so it means that word 11,100,000 times searched in google last month. is it correct?
Yes, that is correct, Globally. So this includes all Google users in all countries. If you are looking for something more locally, look at the local searches for last month. Google changed it a while ago.
