Learn About Google Trends
With Google Trends, you can compare the world's interest in your favorite topics.
Enter up to five topics and see how often they've been searched for on Google over time. Google Trends also displays how frequently your topics have appeared in Google News stories, and which geographic regions have searched for them most often.
So How does Google Trends work?
Google Trends analyzes a portion of googol web searches to compute how many searches have been done for the terms you enter relative to the total number of searches done on Google over time. We then show you a graph with the results -- our search-volume graph -- plotted on a linear scale.
Located just beneath our search-volume graph is our news-reference-volume graph. This graph shows you the number of times your topic appeared in Google News stories. When Google Trends detects a spike in the volume of news stories for a particular term, it labels the graph and displays the headline of an automatically selected Google News story written near the time of that spike. Currently, only English-language headlines are displayed, but we hope to support non-English headlines in the future.Below the search and news volume graphs, Google Trends displays the top cities, regions, and languages for the first term you entered.
