Yahoo! Clues

Yahoo! Clues lets you explore how people are using Yahoo! Search. When you enter a word or phrase in the "Search Term" field and click Discover, you’ll see information about that search term’s popularity over time, across demographic groups, and in different locations.

You can also enter a second search term in the "Compare With" field. This will show you information on both search terms, side by side.

This tool is similar to Google Insights  for Search
