It's not a big trick, but i just found out that, people who build sites around buyer keywords, get a really nice click through rate. But they only fail, since seo is a major problem and lot of people are competing. So i just realized that we could use yahoo answers to drive traffic to our websites. Also creating product review videos for those terms on youtube would help a lot as people would come to our site looking for some more information, but we would not provide them the info they need and force them to click on our ads. just trying to help..... Happy new year.
