You recommend Traffic Travis for market research. I already own SEO Elite and Micro Niche Finder. Wouldn't one of these programs work just as well as Traffic Travis? I'd rather not purchase another software program if I don't have to.
With google sets, you type in a few of your targeted keywords, and it comes up with more suggestions related to the terms you entered. I use it mainly for LSI phrases or other ideas for keywords, which perhaps I left out in previous research.
