Official Google Blog: Google Domestic Trends: tracking economic sectors
September 4th, 2009 Posted in Google
Google Domestic Trends tracks Google search traffic across specific sectors of the economy. The changes in the search volume of a given sector on google.com may provide useful economic insight. We’ve created 23 indexes that track the major economic sectors, such as retail, auto and unemployment.
For example, the Google Luxuries Index tracks queries like [jewelry], [rings], [diamond], [ring], [jewelers], [tiffany] and so forth. As you can see from the screenshot below, this index has seasonal spikes in December — however, in the last two years there has been a pronounced decrease as the recession made consumers wary of spending on luxury items.
