I have an exact match domain for a specific product that gets 16K searches a month. Another one with similar situation (but not a .org,.net.com, url) with over 200k. According to Google Keyword Tool, the keyword is about 1/3 full for competition. Market Samurai lists the main SEO competition as the big sites such as Amazon, Target, the product maker, Walmart, and a few other product sites. I am sure it is worth a try for an Amazon affiliate, but what are ya'lls opinion in keyword situations like this?
