I'm trying out a tool called SEO Profiler, and that tool has compiled a report on my website, www.mauitradewinds.com
To my surprise, it reports an "error" in the form of "duplicate page content", which could result in a ranking penalty by Google. A screenshot is attached. I don't know how to resolve this. There is no duplicate page on my server -- only index.htm -- which is the main page. Any suggestions?
