Hi Jacob and Lynn,
Thank you for the responses. The servers are based in the same country, and Lynn I think I agree with you that it might be a red herring. One thing I noticed just yesterday (while using MOZ's crawl results btw) is that each new property / product we launch has two pages. Our system creates a page using the identical content and identical page title under the root domain and under /investments. For example:
http://patchofland.com/investments/single-family-rehab-in-new-jersey.html
and
http://patchofland.com/single-family-rehab-in-new-jersey.html
Could it be that we are such a new site, with such few links, that a duplicate content penalty like that on a significant percentage of our pages could cause us to drop that far?
Thank you again!
Jason
