The search volume corresponds to the monthly number of user queries made for a given keyword on a search engine.
This data is derived from Google Keyword Planner and collected each month with a delay of about 3 months, the time it takes Google to display this data.
Warning: Google displays by default the average search volume over 12 months while Myposeo collects the exact search volume each month to take into account seasonality.
In the interface, you can view in the Trend column, the last 12 values collected in Adwords. When the mouse moves over the bars, a bubble info appears with the volume and the corresponding month
