Google Trends
Google Trends is an online tool that provides information on the relative popularity of search terms (actual search volumes for keywords are no longer provided). The results can be filtered based on country, time period, interest category, and search type (Google web, image, news, YouTube & Google Shopping). Users can compare the popularity of several search terms and the data is presented on two graphs (interest over time & interest by region). Google Trends also provides related queries for each search term queried.
