I've stumbled upon a keyword with 450k exact monthly searches. All the results in google are for a related search term, but not the exact one. I am having a hard time figuring out what to write as there is no content elsewhere. The websites ranking on the first page are selling that similar product (big sellers such as amazon, walmart, thinkgeek etc). So what should I write? Is this a bad keyword because there is no niche or does that just mean more opportunity?
