Google has a multitude of other tools that can be useful. This page introduces a sampling of the tools, which are available for free.
Google News pulls articles from a variety of news sources from all over the world. The settings can be customized to feature the type of news that you are interested in, as well as your preferred news sources. There is an option to change the language of the news, although this will affect the type of news that is featured.
Google Trends shows how often a term is searched for worldwide. This can be useful to find out interest in certain topics or cultural attitudes, in addition to tracking illnesses.
Example: Type "cold symptoms" and observe the months when people are more likely to look that up. We can assume that they are looking it up because either they or someone they know may be experiencing cold symptoms.
Google's Public Data Explorer allows access to public datasets from various organizations. The information is viewed through visualizations, and is a useful way to see a large amount of information at once.
Example: Type "unemployment" and then select a source from the list of results. If you select the U.S. Bureau of Labor Statistics, then you can see the unemployment rate of the US. Additionally, you can select specific states to see how the unemployment rate differs.
Using Google to search by using an image can be useful if you want to find similar images, or to find out the copyright of an image.
