Described as “Google Trends in reverse,” Correlate was developed to find queries with corresponding patterns that are based on real-world trends. You’re given the option to upload data or search for key terms, which Google examines and generates matching patterns for, then creates an interactive chart with the data set. If that’s not enough, the research tool lets you draw patterns on a graph and returns correlations based on web search activity. Ridiculous. Being that Google already has a handful of search data tools out there, we’re hoping something gets phased out in exchange for Correlate.
