Some time in the last few months, the Google ranking for this site dropped dramatically, going from the first result for "Investigative Economics" to somwhere around the 30th or 40th.
While search rankings can change for a whole host of reasons, nothing has changed with respect to the site that would warrant such a large shift. No errors or warnings are listed in webmaster tools, and other search engines like Bing and DuckDuckGo still show the site as the first result.
Google has not responded to inquiries about the change. I'm still trying to garner a response, but please reach out if you have any insight as to what it might be related to.
