As I know, many people say that market samurai is an awesome tool which helps you to do keyword research and filter out potential keywords. Recently someone told me that buying market samurai is just wasting money, when I asked why, he said
- you can use TrafficTravis free version
- google adwords tool
- and about a firefox add-on called rankchecker addon !!
what do you think ? what are the advantages of market samurai than the other keyword researching tools ?
