Popularity of search terms in google

How can approximation of search terms popularity in google can be done?

Hi there experts .
I'm thinking of a method for search term popularity approximation (google).All I have is the basic assumption that web sites knnow what the 'people' want - so the above might be indicated by the number of indexed sites with these terms.
I need something better - in order to choose a better domain name.
Can this be done using the time of the search and the number of results google rettieves?
Thanks .

I'm not sure if this is what you're looking for but I would try the Overture search term suggestion tool or the Google Adwords keyword suggestion.

Thanks man .
I'm going to check these references ,though I think google Adwords is a comercial tool .
Do you find the Domain name of a site something crucial with it holding the Key-terms?

KingCrimson,
Adwords is commercial but, you can set up a "Campaign", search for keywords and then, not "activate" the campaign.

As far as keywords and domain names, there's been a lot written here. Try a search.
