What does Google Trends mean?
A useful tool on the Google search engine that allows you to see how often a keyword or term is searched for. Results are relative, meaning that the tool is best used for comparing keywords and phrases. Google Trends also shows where the searches came from, and how the volume of searches for particular keywords changes over time.
In addition to Google Trends, Google launched Google hot trends. This extra tool displays the 20 hottest searches and searches terms of the past hour in America. This tool is useful for finding things that are experiencing a surge in popularity, the searches being displayed in a volume graph.
