Definition: Hot Trends is a measurement of Google search trends. It is similar to Google Trends and Google Zeitgeist, except that it is updated multiple times per day.
The service does not measure the absolute popularity of search terms, as these don't tend to change much over time. Instead, Hot Trends looks for terms that have rapidly gained popularity relative to their previous rank.
Google launched the service in May of 2007, and it can be found on the Web at www.google.com/trends/hottrends.
