Google Trends, the service that compares the volume of searches, to see how popular certain search terms are across geographic regions, cities, and languages, has now been updated to show numbers on the vertical axis. You can now see numbers on the graph download to a spreadsheet.
Here's what vanilla searches looks like on its own:
You'll notice a number at the top of the graph as well as on the y-axis of the graph itself. These numbers don't refer to exact search-volume figures. Instead, in the same way that a map might “scale” to a certain size, Google Trends scales the first term you've entered so that its average search volume is 1.00 in the chosen time period. So in the example on the right, 1.00 is the average search volume of vanilla ice cream from 2004 to present. We can then see a spike in mid-2006 which crosses the 3.00 line, indicating that search traffic is approximately 3 times the average for all years. Read more about how we scale the data. [Google Blog]
