Thank you for the suggestion, but did you ever tried it by yourself. I had tried their service and the research tool didn't show me any results. Moreover I am targeting Latin America(separately each country...) and they targets only a few country..... Thanks for the response, Anyone else, any option...

Well... With the new changed politic for the traffic estimator how is possible to do business plan for the specific niche... Anyone can suggest keyword traffic estimator alternative... Please
