Just a PSA for everyone wanting to try this method.
First Ill say, this method works. I have made amazon sites in the past and they have made good money. I just wanted to let you know that this isnt a sweat free method. You are going to have to put the hours in and generate GOOD QUALITY CONTENT! That goes for you backlinks too, I have put effort into my forum profiles and it shows. I just started promoting my site (after spending a month building it).
I made 3 high quality forum posts that linked to a highly relevant fresh piece of content and here are the results after about 8 hours. Prior to this, my site was getting about 5 hits a week.
In the past when I was younger, I would always half-ass this kind of stuff. If you want to make money in your particular niche, guess what? Your site needs to kick the competitions ass, make your site better! Better reviews, better layout, netter natural seo. Website growth is exponential, not linear. Today is the first day I saw any results, I dont expect to see any decent profit for 6 months.
Have faith in the method, get to work building something you can be proud of.
The results will come.
