Google Correlate Google Correlate is an experimental new tool on Google Labs which lets you use the same methodology and data as Google Flu Trends. What is Google Correlate? Google Correlate is like Google Trends in reverse. With Google Trends, you type in a query and get back a series of its frequency (over time, or in each US state). With Google Correlate, you enter a data series (the target) and get back queries whose frequency follows a similar pattern.
