I've been using this method now for almost 4 months. It's a very good method and it does work. One thing to watch out for is if you intend to use adsense, do some research on your CPC. I chose a niche in dieting and weight loss. I'm ranked on the 1st page of Google and getting good traffic, in fact the traffic is better than my 5 yr old authority site. Adsense CPC however is around $0.05. Thankfully Amazon is working well which surprises me because Amazon don't use the language of my site.
So thanks to the OP for this great method and I can confirm that it's a worker. I'm planning to do it all again but choose another language.
I'll keep you all posted!
