As far as I know sites and blogs having adequate number of pages with good keywords may get a decent organic traffic and thereby one could survive. My question is how one can get organic traffic for a one page review site that too box review sites with little content ? Whether link building works in such case? Or ad words is the only way out?
You could also try article marketing, submit articles to article directories or also you could try guest blogging. Write good posts and contact blogs in that niche that are willing to publish your article and place a link to your site.
Product review sites are perfect to earn lots of money on affiliates. But it's pretty hard to generate visitors on a single page site, so what I suggest you is to first target long-tailed keywords. Build links on other sites related to your niche, product, review, etc... Article and RSS directories could deliver you good number of back links.
I do agree that I need to learn many things on SEO. But the signature is not to mock at others. I found that forum traffic is useless, mischievous, and sometimes dangerous too for CPC sites. Organic traffic gets the money and genuine visitors, not the curious ones , who just want to peep through others windows! Thank you for the sincere advice.
