Curious tools: Google Correlate

Google Correlate is an experimental new tool on Google Labs which enables you to find queries with a similar pattern to a target data series. The target can either be a real-world trend that you provide (e.g., a data set of event counts over time) or a query that you enter. Google Correlate contains web search activity data from January 2003 to present. The data is updated weekly.

So this is pretty much a great tool to look at real World trends as it uses web search activity data to find queries with a similar pattern to a target data series. Some of the findings can be quite interesting.

Let’s look at this example searching for “losing weight”

And you can clearly see that between December and January is when new years’ resolutions kick in as well as the bikini sindrome in the summer months.

Now, let’s try something a bit more relevant to sport. Let’s try “doping”, as you can see, there are peaks of searches and the highest correlation coefficient is with “what is doping”.

with peaks in May 2010….when Landis admitted taking performance enhancing drugs and pointed the finger at Lance Armstrong.

New Picture (9)The word “Testosterone” has the highest correlation coefficient with “Natural Levels”. And there seems to be a growing interest in such search word, I hope only because people are interested in the science….

The search for “Strength training” really worried me. A part from the highest correlation coefficient with “Exercise” what worries me is the decline in its use for web search. Does it mean we should expected a reduction of interest towards this form of exercise?

So, to double check I looked at the search word “Bodybuilding”…and I got really worried as the highest correlation was with “death index”….whatever that means

Really an interesting tool. You can look at it yourself on:

Another tool is Google Trends. Even cooler, as it allows you to study search volumes and look at specific media-related events. Again, when searching for volumes of searches of the keyword “Doping” specific events where highlighted.


Brilliant stuff from Google Labs. Keep them coming!
