Hi, I wanted to know whether there is a tool from where i can find the top searched keywords on google which have been separated into different categories such as sports, business etc etc or is there any way i can find them?
You can try the Google Adwords suggestion tool. Use your category name as the search and turn synonyms on. NArrow your criteria down from there Hope this helps
Know the most searched keywords thru Google Trends: http://www.google.com/trends or Google Zeitgeist: http://www.google.com/press/zeitgeist.html
