I have been receiving the discount offer to buy Longtail Pro Keywords Finder. Since I am new here and want to use something that can aid me with my research on finding keywords, should I buy Longtail Pro? Is it legit? Any advice on this?
And a bonus question ..
A bit of help on how to research the demands, traffic, and possibilities of money making niches. I have been trying but ended up nowhere most of the time. Please.
