I was looking through AWStats and seeing quite a few requests for https://www.webkeydesign.com/index.rdf which is resulting in 404 Page Not Found errors as I do not have this file and WordPress does not create the RSS feeds at this location. The solution is of course to either create the index.rdf file or simply redirect it.

In cPanel you simply use the Redirects panel to have any url for your site redirect to another page. In this case the redirect ends up going to www.webkeydesign.com/feed/, which is where I actually have RSS feeds for the site.

There is some debate as to why index.rdf is being searched in the first place, but the concensus is that GoogleBot may be defaulting to this location for various sites simply looking for RSS feeds.
