I need some help with finding a good keyword to target when building a site and backlinking. My sites are basically product review pages and I will be trying to make money off of affiliate advertising. It seems that no matter what products my page is about any decent keyword is dominated by big websites that I have no chance in beating like amazon, walmart, kitchenaid, bed bath and beyond... For example lets say my page is all about slow cookers. No matter what variation I use of slow cooker for the keyword like oval slow cookers, programmable slow cookers, or even touch screen slow cookers those big sites dominate the results. So my question is how do you find good keywords (500-2000 exact searches/month) that will bring targeted traffic to your site when your site is a product review site? How do you avoid those big name sites?
