As with a lot of other Google Products this one is marked as "Beta", but delivers great results you won't find anywhere else.

Google Insights for Search lets you compare search patterns across different regions, categories and time. It provides search volume data and let's you narrow it down to specific categories like finance, sports, movies, etc.

It will let you know how the search terms that you enter are being used geographically. So for example if you'd like to know what are the top ten countries that search for "Wine", you could do this in about 3 seconds using Google Insights. Or if you wanted to see the search volume for "Hotels in new York" you would get this:



Also you will get a list of Search terms that are related to your query and related Rising searches. Overall it's a great tool and there is not a drop of waste in it.

One cool feature that Google could add is the ability to save your searches into your Google Account so that you wouldn't have to redo them every time you visit the site.
