If you have ever had problems identifying niches, or you build a site that you think will be profitable, and its not, then Gary Harvey might have the answer. He has opened up a new site (it's called a membership site, but it is a one-time payment only). Gary has done extensive research into niche markets, and found 37 ways to identify hot niches, and check them for profitability.
I have had a look around the site, and have to say, there is a huge amount of information in there. Not everything on the site is about finding hot niches, as Gary covers other areas on affiliate marketing as well (with lots of great resources), but for anyone who has troubles identifying niches, this site will certainly help you.
A lot of the information on the site is freely available on the web, but its conveniently packaged into one site - a niche resource site, if you like. However, having said that its freely available, there are a lot of resources I have never seen before (Gary has spent many hours researching and compiling). I will certainly get good value out of this site.
All in all, this site is a great resource, and one I'll be using myself. Gary is continuing to add new stuff all the time, and the price is due to go up soon, so if you're interested, get in now.
