I never use it. Overture combines lots of phrases into one phrase and they often don't show the phrases in the same order that people typed them in. It is very limited. There are several other ones out there you can use. Wordtracker, Keyworddiscovery, and wordz. They all cost money. Wordtracker does have a free version that is helpful. None of them show an accurate number of times the terms are typed in. You can only find out by actually ranking for the term using PPC or SEO.
