We get existing volume data from Google Keyword Planner, and pair it with clickstream data to create a model that gives very accurate search volumes for almost any keyword. 

Note: Clickstream data is anonymized data from the apps and plugins that you add to your browser. 

As a result, we can show you certain data that Google Keyword Planner doesn't: 

Monthly Updates

We update our search volumes every month and catch all the trends. 

Un-grouping close variants

We un-group close variants that Google Keyword Planner groups together: 

Clicks

We use clickstream data to determine the CTR curve for every individual keyword (where we have enough data to be certain.) This allows us to check if people are clicking through to the search results, which we show as the "Clicks" metric.
