How Google Trends work

Google Trends computes a search volume in proportion to the total number of every other search on Google and then provides viewers with an index graph.

The result generated is then normalized with a certain variable so that they start at 0 January 1, 2004.  

Just below the X-axis of the Google index graph one can see the News reference volume which shows the number of times the subject appeared in Google News stories.
