I have a Wordpress site and would like to track the basic statistics for the site; visitor numbers, visitor numbers for specific pages on the site, download statistics etc. For that purpose, I have installed the "Google Analytics for Wordpress"-plugin (http://wordpress.org/extend/plugins/google-analytics-for-wordpress/), and this now tracks much of the information that I want via Google Analytics.
However, the download statistics don't work as I want it to: It only tracks files that have been uploaded via the Wordpress Dashboard and that go into the default upload folders (e.g. .../wp-content/uploads/2013/04). I have my files for download in custom folders (e.g. in .../documents), but these are not tracked by Google Analytics with the above plugin.
I have looked into setting this up manually in Google Analytics, but to be honest I don't quite understand how to do this. Alternatively, a Wordpress plugin that tracks the downloads of files from custom folders would work for me. There are a number of plugins for this purpose (e.g. http://wordpress.org/extend/plugins/simple-download-monitor/), but it is not clear to me if they are still maintained and are reliable.
So what simple and reliable solution would you recommend for download statistics from custom folders on a Wordpress site?
Thanks in advance for any help!
