I will write six 100-word product descriptions for you using Raven Tools, the best SEO/SEM tool, period. If you want SEO that will actually get your website ranking, Raven Tools is the tool you've been looking for. I can provide screenshots (or other proof, if you'd like) to prove that I have an account and I'll be using it on your project.
I can add specifications to your product descriptions at no extra charge and they will not count toward the 100-word count. Let me know if you want them added in. Please note that you'll have to direct me to the OEM's product page or similar.
