Google and MSN Search volume/Month? How?

[ramki]

Hi,
From where this keyword research tool is fetching Google & MSN search volume per month?. Google trends never talk about numbers, that only shows graph. From where this search volume are coming for Google & MSN?

Please click the link below & search for a keyword

Is that data is from Adwords click thru & ad center click thru?

Please Help :)

regards

From the Tool Limitations on that page...

Please note our tool currently assumes Google having double Yahoo!'s search traffic and Yahoo! having double MSN's search volume. Depending on your topic / vertical and your geographic location the search engines may have vastly different search volumes. The tool can only possibly offer approximations. Exact search volumes are hard to find due to vanity searches, click bots, rank checkers, and other forms of automated traffic. Exceptionally valuable search terms show far greater volume than they actually have due to various competitive commercial forces causing greater automated search traffic.
