Hi buddy,
I am familiar with the word stream keyword suggestion tool.
WordStream eliminates the margin for error that other keyword suggestion tools have by helping you sculpt your keyword list instead of building from the ground up every time. Rather than guessing and entering 5-10 of what you think are important keywords and getting a list of 100-200 words that may or may not be related, with WordStream, you rely on your real data to create a continuously growing list of keywords that you know are bringing traffic to your site.
With the WordStream Keyword Suggestion Tool, you are presented with new keyword suggestions and you determine what's relevant and what isn't. If WordStream offers you a keyword that seems like it would relate to your site, but it doesn't, you can file it away as a "negative keyword," and WordStream will remember that and suggest related words as negatives in the future.
