So I'm dabbling with adwords once again and was wondering what the best keyword-research tool is these days (other than using adwords keyword suggestion tool).
The main problem I'm having with the tool google provides is finding long-tail derivative keywords for a "seed" keyword.
For example, I want to find variations of the keyword "wet panties" that are long-tail (or longer-tail) in nature, such as "female wet-panties", "wet-panties for sale".
So far I've tried out Market Samurai's trial but I get NADA results.. never found that tool too useful for some reason.
Keyword Butler was able to help me out a little.
Keyword Elite by Brad Callen is $100 and I'm not sure it's going to do what it says, so I'll hold off.
Any suggestions here fellas?
Cheers
