MSN adCenter has released a cool keyword forecasting tool.
Type in one or more keywords and you’ll get a breakdown as to the number of searches over the past year, and the forecasted number of searches for the next few months. It’s a great way to do more accurate projections on your traffic and sales volume for the near future.
As well, MSN will provide you with data about the demographics of the people who are searching for that particular keyword, namely age and gender.
No MSN adCenter account is required to use the tool.
