Read my blog post on Keyword Research Pro, I listed down what you can do with this tool and what are the shortfall. Feel free to comment ; )
ya you can use keyword tracker .... as i always use because its have 7 days trial version and cheaper as well
Market Samurai uses the google tool. I would say learn keyword basics with the free tool then graduate yourself to the free trial of MS. Its important to understand how to interpret the data that is returned by this software.
Hello The brainstorming tool from SiteSell that's mentioned above is Brainstormer, which is part of Site Build It! This is not just a keyword research tool. Brainstormer actually helps you make better decisions about your site's niche, and then also offers realistic keyword numbers to enable you to build web pages that are in demand at the search engines. This tool enables you to build a solid foundation, and then as you progress with your site building - focusing on building your business - there is another module in SBI! that helps you monetize your site. Site Build It! is about building a successful online business, and no just about web design, or keywords, or all the other techie stuff. And yes, SBI is now available for $29.99 per month. You can see what you get here: http://tools.sitesell.com/ Hope that helps. Colin
