Thanks so much Rufat, will do that for sure. But I may need to rephrase my question...could Google Adwords be used as a good guage of the popularity of a particular niche?

I'm sure after going through those lessons you'll get the answer to your question. But for now I can say yes. If you google a niche that you have interest in through google and find many paid ads at the top of Google's results and on right side that means the niche you want to step into is popular enough.

Rufat, thank you again for the help, that's exactly what I was looking for
