Hi, I am searching for keyword tool which can show me hottest niches and keywords for my marketing campaigns and affiliate marketing in order to boost sales and traffic. I can show popular adwords keywords, popular searchings.. I have seen some tools like keyword elite, but still i cant be sure which one is the best. I am looking forward to hear your experiences and comments. Thanks.
Wordtracker has free tool: freekeywords.wordtracker.com/ Another approach could be this site: 43things.com 43things is a site where people list the things that they want to achieve, their objectives and desires. Its a good site for discovering what members of the site need or want. Guess this site is best if you start from scratch and you're looking for a specific niche.
